Contact lenses are wonderful because they provide a near-normal vision experience without corrective glasses. But they can be easily forgotten. When preparing to sleep, even for a nap, is not the time to forget about them.

To help contact lens wearers understand the implications of sleeping in their lenses, Lens.com published an informative guide.

Can you sleep in contact lenses?

Did you know that sleeping with regular contact lenses can result in severe infection and put you at risk for vision loss? Some contact lenses, like extended wear contacts, are meant to be worn overnight. However, many are not. You can only sleep in contact lenses designed for overnight wear, such as Acuvue Oasys with Hydraclear Plus, which is approved for up to six consecutive nights of wear. 

Contact lenses are medical devices that require proper care and handling to avoid severe side effects. Yet, as little as two percent of contact lens wearers report following their eye care provider’s instructions.

What happens if you sleep with contacts lenses in?

It’s important to know the implications of sleeping in contact lenses not designed for extended wear or if they are left in too long.

  • Eye Infections. Eye infections are the most significant risk of sleeping in contact lenses not approved for extended wear. When you sleep in your contact lenses, your risk of contracting eye infections increases six to eight times. The most common infection is called conjunctivitis or pink eye. This common eye infection is mainly caused by wearing contact lenses overnight, but it can also be caused by allergies or coming into contact with someone who has it. Sleeping with your contact lenses makes you more susceptible to pink eye because your contact lenses can leave microscopic tears on your cornea, thus increasing your odds of bacteria entering and getting trapped in your eye and leading to infection.
  • Hypoxia. Oxygen is essential for the healthy function of your eyes. There are no blood vessels in your corneas (the clear tissue at the front and center of your eye), which means they get their oxygen directly from the air. Contact lenses reduce the amount of oxygen that reaches your cornea. Now imagine sleeping with contact lenses in your eyes. With our eyes shut and contact lenses, the amount of oxygen is greatly restricted and can lead to hypoxia of the eye. This extreme oxygen deprivation can cause warping, scarring, pain, and vision loss.
  • Corneal Ulcers. If your contact lenses are not taken out and cared for properly, you may cause so much irritation that you cause corneal ulcers, or open sores on the cornea, to form. These ulcers can even become so severe that they require a corneal transplant using donor tissue. Those who sleep with contact lenses not approved for extended wear are five times more likely to develop corneal infections, permanently damaging their vision.
  • Contact Lens-induced Acute Red Eye (CLARE). Tight Lens Syndrome or Contact Lens Overwear Syndrome is usually marked by light sensitivity, redness, tearing, and decreased vision. When a contact lens fits too tightly, it will stick to the cornea like a suction cup, and this will cause the cornea to swell. If not treated, You could be at risk for a severe infection that can cause a corneal ulcer leading to permanent scarring and vision loss. Contact lenses are like tiny sponges; they expand when they are moist and shrink when they dry out.
  • Giant Papillary Conjunctivitis (GPC). Wearing your contact lenses for prolonged periods or overnight can cause bumps to form underneath your eyelids called GPCs. If you wear your contacts while you sleep, you have the greatest chance of experiencing this unpleasant condition. These bumps can result in your contact lenses no longer fitting properly. If this happens, your eye care provider may ask you to stop wearing your contact lenses for a week and see if your symptoms subside.

Why does sleeping with contact lenses increase your risk of an eye infection?

After wearing your lenses all day long, napping or falling asleep means your lenses have collected pollutants, bacteria, and dirt that could increase your risk of complications. As your eye and contact lens becomes dehydrated in your sleep, the lens starts to shrink and tear at your cornea, and these microscopic tears allow an entry point for bacteria to get into your eye. Sleeping in contact lenses increases your chance of getting an eye infection six to eight times.

What to do if you accidentally sleep with contact lenses in?

Attempt to remove your contact lenses as soon as you’ve discovered that you’ve fallen asleep with them in your eyes. Make sure you follow your standard hygiene practices. If you cannot remove them easily, stop! Tugging at a dehydrated lens attached to your eye can cause tearing. Instead, place several drops of sterile contact solution on your eyes or lubricating drops. Blink several times. And try again.

After successfully removing your contact lenses, pay attention to how your eyes feel. Do not wear contact lenses for at least one full day to allow your eyes to heal. Contact your eye care provider immediately if you notice any symptoms of infection or discomfort. The signs of an eye infection are blurred vision, redness, excessive watering, and discharge from the eye. If you think you have an eye infection, your eye doctor may want to test your contact lenses, so be sure to take those with you when you visit.

Always practice safe habits following the guidelines your eye care professional provided and check with them whenever you’re in doubt.

If you are guilty of sleeping or taking naps in your contact lenses, it’s time to change your eye care routine. You may want to consider taking out your contact lenses after dinner and switching to eyeglasses so you don’t forget them before bedtime. If you are a fan of naps or have an unpredictable schedule, visit your eye care provider and ask if extended-wear contact lenses are for you.

Why are some contact lenses FDA-approved for overnight or extended wear while others aren’t?

The simplest reason why not all contact lenses are FDA-approved for overnight wear is that contact lens manufacturers have to apply for FDA approval. Applying for FDA approval is a lengthy process that requires submitting studies and research documents and passing clinical trials. If a manufacturer wants FDA approval, they’d have to spend considerable time and resources.

Another reason is that contact lenses designed for overnight wear are made of thinner material compared to daily wear contact lenses.

Many contact lens brands that are FDA-approved for overnight wear are made with silicone hydrogel, which is significantly more breathable than standard hydrogel. Silicone hydrogel allows for much better oxygen transmissibility, which is essential when wearing contact lenses for extended periods.

Which contact lenses can you sleep in?

You can only sleep in contact lenses that are designed for overnight wear. Popular contact lenses rated for overnight usage include:

  • Acuvue Oasys with Hydraclear Plus can be worn daily for two weeks or continuously for up to six nights and seven days, after which they must be removed, disposed of, and replaced with a new pair of lenses. These contact lenses feature Acuvue’s innovative Hydraclear Plus. Inspired by how the eye’s tear film works, this wetting agent keeps the contacts wet and smooth for all-day comfort. These contacts block more than 99 percent of UVB and 95 percent of UVA rays – some of the highest levels you’ll find on the market today.
  • AirOptix plus HydraGlyde combines two unique technologies into one lens: SmartShield Technology and HydraGlyde Moisture Matrix technology. SmartShield Technology creates an ultra-thin protective layer to help shield your lenses from deposits and provides long-lasting comfort. HydraGlyde Moisture Matrix, on the other hand, attracts and maintains surface moisture on the lens for up to 16 hours. SmartShield Technology and HydraGlyde Moisture Matrix technology make Air Optix plus HydraGlyde very comfortable.
  • Biofinity contact lenses bring a remarkable balance of comfort and breathability in a monthly disposable lens. They are FDA-approved for extended wear, meaning they can be worn continuously for up to six nights and seven days before they need to be replaced. These contacts feature CooperVision’s patented Aquaform® Technology, which locks in water so you can enjoy all-day comfort. They also have smooth, rounded edges, enhancing comfort by minimizing interaction between your contact lenses and eyelids.
  • PureVision 2 HD contact lenses are another popular brand rated for night and day wear. Featuring Bausch + Lomb’s innovative High Definition™ Optics, these contact lenses help you see enhanced contrast, sharper details, and reduced glare, even in low light conditions. They reduce halos and give a crisp, clear vision while using digital devices or in low-light conditions. They’re made of a silicone hydrogel lens material that allows plenty of oxygen to reach your eyes, which they need to stay white and healthy.

The lenses above have been approved by the FDA for use while asleep. If you already wear these contact lenses, ask your eye care provider before using contacts during sleep. Each individual’s eye health is different and your eye care provider needs to evaluate the overall health of your eye before approving overnight use.

Can you nap while wearing contact lenses?

Generally, no, you should not nap or sleep with contact lenses. This applies to all contact lens brands and types, unless specified. Falling asleep with your contact lenses could lead to infection and irritation. While modern soft contact lenses have incredible technology to ensure enough oxygen passes through the lenses in daily wear, having your eyes closed while you sleep reduces available oxygen and prevents tears from washing your eye under the contact lenses. This can potentially cause problems to your eyes through hypoxia of the eyes unless you use specific lenses designed for extended wear, as directed by your eye care professional.

Everyone faces different challenges when getting through each day, but some days are occasionally a tad more exhausting than others. Whether you are a new parent, finishing up work for a deadline, studying for an important exam, or going through health issues that keep you lethargic all day long, there’s one thing we can all agree on, and that is a nap. Studies have shown that naps boost productivity by improving alertness, performance, and mood.

Rather than avoid taking naps, consider talking to your doctor about changing your prescription to an extended-wear contact lens.

What if I fall asleep with the contact lenses for just 10 minutes?

The duration does make a difference, but it is not the only factor to consider. In general, the more time spent sleeping in contact lenses, the greater the risk that you will develop symptoms of infection or inflammation and suffer from the more severe consequences. For example, if you sometimes fall asleep during your work transit or take naps between 10 and 40 minutes long, you are likely not exposing yourself to any long-term health-related risks. You might, however, still experience blurred vision and dry eyes for a short period. If you’re asleep for an extended period of one or more hours, then your contact lenses can dry up in your eyes, which can lead to discomfort or a scratching sensation in your eyes when you open them.

The type of contact lenses you wear matters, too. Silicone hydrogel lenses allow more oxygen to the cornea, so your eyes won’t get sore. On the other hand, hydrogel lenses might cause some redness, irritation, and burning when you wake up– which could even damage your cornea. With shorter naps, these issues are less likely to occur.

The state your eyes are in before falling asleep also matters. If you have been using your contacts only for a few hours before going to bed, then there is a lower risk of your eyes getting irritated than if you have been wearing them all day. This is because contact lenses accumulate dirt and dust, such as when worn for extended periods or throughout the day. However, if you fall asleep with your contacts in the evening and stay in your eyes all night, this is more problematic.

How do you wear contact lenses safely?

Your eye health is just too important to take a chance. Consider speaking with your eye care professional about switching to contact lenses approved for extended wear when in doubt.

If you’ve accidentally slept in your contact lenses for brief periods or rarely, here are tips to help:

  • Attempt to remove your contact lenses as soon as you realize you’ve slept in them. But do not sidestep your regular hygiene process, such as washing your hands.
  • Always have a backup plan. Carry a spare set of lenses or a pair of eyeglasses. It’s also a good idea to keep contact solution or eye drops in your purse, backpack, or office.
  • If you’ve fallen asleep on an overnight trip and realize you didn’t bring your contact lenses or cleaning supplies, find a pharmacy as soon as possible so that you can remove and clean your lenses. At the very least, put in eye drops so your lens can rehydrate and reduce the pressure on your cornea, and it is imperative to remove your lens as soon as possible.
  • Never put your contact lenses in your mouth to moisten or clean them. Saliva is not sterile and will increase the risk of an eye infection.
  • Before wearing your contact lenses again, ensure they are thoroughly cleaned and inspect them for small tears or other imperfections. If you notice any irregularities, throw them away. And start with a fresh pair. It’s always a good idea to go at least one day without contact lenses if you’ve slept in them; this will give your eyes a chance to recover.
  • If you experience any symptoms of an eye infection or discomfort, seek care from your eye care professional.

Always practice safe habits and check with your eye care professional whenever you doubt.

Young people who vape more likely to report chronic stress

Young people who use e-cigarettes had poorer quality of life but lower risks of some signs of ill health, such as high blood pressure, although these findings did not reach statistical significance.

Published

on

Young people who have used e-cigarettes are more than twice as likely to report experiencing chronic stress, according to a study by Dr Teresa To, a senior scientist at The Hospital for Sick Children (SickKids) in Toronto, Canada.

She said: “Research is starting to show how vaping affects young people’s physical and mental health. For example, our previous research has shown that those who vape are more likely to suffer an asthma attack. In this study we were particularly interested in the relationship between vaping, mental health and quality of life among young people.”

The researchers used data from the Canadian Health Measures Surveys, a national survey designed to represent the Canadian population. It included 905 people aged between 15 and 30 years, of which 115 (12.7%) said they had used e-cigarettes.

The data showed that although young people who vaped were more likely to be physically active, they were also more likely to report experiencing extreme chronic stress in their lives.

Dr To said: “Chronic stress can lead to mental health conditions such as anxiety and depression. It’s important for young people experiencing chronic stress to be given support early on to help them avoid resorting to unhealthy coping mechanisms like vaping or smoking. Vaping is not an effective way to cope with stress, but stress and anxiety can trigger vape cravings, and make it harder for a user to quit.”

The researchers point out that while their study shows a link between vaping and stress in young people, it does not show whether stress caused an increase in vaping, or whether vaping increased experiences of stress, or if another factor led to an increase in both. However, their research did take into account other factors that are known to influence stress, such as income, alcohol consumption and health conditions like asthma and diabetes.

Dr To added: “We do not know why young people using e-cigarettes tend to be more physically active, but it could be that they are trying to control their weight with exercise and believe vaping could help.”

The results also indicated that young people who use e-cigarettes had poorer quality of life but lower risks of some signs of ill health, such as high blood pressure, although these findings did not reach statistical significance.

“At the time of the study, this group of young people had good physical health overall; however, we need to study the effects of e-cigarettes in the longer term to understand their impact on young people’s health. We know that stress induces oxidative stress and inflammation in the body and these play an important role in the risk of developing chronic conditions such as asthma, diabetes and cardiovascular disease,” Dr To added.

Professor Elif Dağlı, who is chair of the European Respiratory Society’s group on Tobacco, smoking control and health education, and was not involved in the research, said: “This study suggests a link between vaping and stress among young people, and it adds to what we already know about the effects of vaping on young people’s health. Vaping is still relatively new, but the numbers of children and young people using e-cigarettes are rising rapidly. We need more research on the impacts of vaping, but we also need to raise awareness of the harms of using e-cigarettes and provide support to help young people avoid or quit vaping.

“This is one of several studies about the effects of vaping that are being presented at the European Respiratory Society International Congress. In particular, we will be examining the influence of favoured e-cigarettes and looking for ways to end the epidemic of vaping among children and adolescents.”

Blackbough leads environmental awareness campaign with locals

Published

on

In the picturesque paradise of Siargao Island, Jemina Ty, the creative force behind the globally celebrated swimwear brand Blackbough, takes the helm as the leader spearheading a sustainability campaign, hand in hand with the local community.

With its pristine islands, stunning white sand beaches, and sprawling coconut fields, Siargao Island has captivated beach-lovers and adventure-seekers from all over the world. However, this idyllic destination in the southeastern region of the Philippines is facing threats due to plastic pollution and environmental degradation. In response, Blackbough recently organized a beach cleanup campaign to protect Siargao Island and raise awareness among locals and tourists alike.

Ty pointed out, “By 2050, there’s a good chance that we’ll see more plastic in the ocean than fish. That’s why through this initiative, we hope to create a chain reaction and encourage people to be more mindful of their actions and to make choices that nurture the environment.”

The Blackbough Swim Team led by Chief Executive Officer and Founder Jemina Ty accumulated a total of 100 sacks of plastic waste and debris during their coastal clean-up activity at Malinao Beach, General Luna, Siargao.

Under Ty’s leadership, Blackbough became a widely followed international swimwear brand with a heart for sustainability. The company is committed to reducing its environmental footprint by using recycled nylon, investing in ethical factories, repurposing scrap fabrics to accessories, and incorporating recyclable and reusable packaging options. By offering stylish and eco-friendly swimwear, Blackbough encourages customers to make more sustainable choices.

“At Blackbough, we believe that every journey towards sustainability begins with a single step. Leveraging Blackbough’s global presence, we aim to showcase the beauty of our Philippine islands and the importance of taking care of them.” 

The beach cleanup event took place at Malinao Beach, General Luna drawing over a hundred volunteers from diverse backgrounds, including tourists, locals, and stakeholders. Their collective effort resulted in the removal of 100 sacks of plastic waste and debris, offering participants a firsthand perspective on the detrimental effects of pollution on the island.

The Blackbough team, composed of young, creative, and passionate individuals who champion various causes such as marine life conservation and environmental preservation, includes team members based on Siargao Island. Ty acknowledged their commitment, saying, “Siargao is not just a location for us; it’s also home to many of our amazing team members. I recognize that it’s my responsibility to contribute positively to the communities and societies where we operate.”

Beyond cleaning up the beach, Blackbough’s campaign is a call to arms for travelers, environmental enthusiasts, and conscious consumers to begin their sustainability journey. Siargao Island is just the starting point for Blackbough’s beach cleanup initiatives, marking the launch of their Clean Beach Campaign, a series of beach cleanup activities in collaboration with various local communities across the Philippine islands as part of Blackbough’s advocacy for sustainability and environmental protection.

Ty believes in being proactive when it comes to addressing environmental issues. Ty emphasized, “I think that we should not wait for our beaches to reach a critical level of degradation before we act. We hope for everyone’s support as we pursue our mission to protect the country’s beaches. Together, we can make a lasting impact and inspire others to join us on this journey.”

As part of its journey towards sustainability, Blackbough has launched a fundraising drive dubbed “Donate to Clean our Coasts” on its website’s checkout page, running until mid-October. One hundred percent of the proceeds raised through this campaign will be dedicated to supporting the International Coastal Cleanup Philippines, a non-profit volunteer organization dedicated to cleaning up marine debris and promoting ocean conservation. Blackbough has also pledged to match the cumulative donations made during the month of September.

All work and no play will really make a dull life – research

‘Achievement’ and ‘conformity’ values had no impact on happiness whatsoever. However, the researchers believe achievement could impact on happiness when linked to job satisfaction or the amount of days worked.

Published

on

A study across three countries led by the Department of Psychology’s Dr Paul Hanel discovered people who prioritised achievement over enjoyment were less happy on the next day. Whereas those who aimed for freedom said they had a 13% increase in well-being, recording better sleep quality and life satisfaction. And participants who tried to relax and follow their hobbies recorded an average well-being boost of 8% and a 10% drop in stress and anxiety.

Dr Hanel worked with colleagues at the University of Bath on the Journal of Personality-published study. For the first time, it explored how following various values impacts our happiness.

Dr Hanel said: “We all know the old saying ‘All work and no play makes Jack a dull boy’ and this study shows it might actually be true. There is no benefit to well-being in prioritising achievement over fun and autonomy. This research shows that there are real benefits to having a balanced life and taking time to focus on enjoying ourselves and following individual goals. Ironically by doing this, people could in fact be more successful as they will be more relaxed, happier and satisfied.”

The study –Value Fulfilment and Well-being: Clarifying Directions Over Time – examined more than 180 people in India, Turkey and the UK. They filled in a diary across nine days and recorded how following different values affected them.

Interestingly all nationalities reported the same results with the following of ‘hedonism’ and ‘self-direction’ values leading to increased happiness. ‘Achievement’ and ‘conformity’ values had no impact on happiness whatsoever. However, the researchers believe achievement could impact on happiness when linked to job satisfaction or the amount of days worked.

Professor Greg Maio, University of Bath, said: “This multination project was an exciting foray into questions about how values affect well-being in day-to-day life. People often spend most of their days working hard for their daily income, studies, and careers. Against this backdrop, where achievement-oriented values have ring-fenced a great portion of our time, we found that it helps to value freedom and other values just enough to bring in balance and recovery.”

In the future, it will be interesting to consider how this pattern interacts with relevant traits, such as conscientiousness, and situational contexts, such as type of employment, Maio added.

It is hoped the research will now influence mental health provision and influence therapeutic give to clients.

Dr Hanel added: “Our research further shows that it might be more important to focus on increasing happiness rather than reducing anxiety and stress, which is of course also important, just not as much.”

The study was published in collaboration with Hamdullah Tunç, Divija Bhasin, and Dr Lukas Litzellachner.
