Attending a function or a party but do not want to wear spectacles which can spoil your entire look? What about your smokey eye makeup? It will not be visible if you wear your glasses. At this hour, contact lenses become your biggest saviour and save you from your fashion compromise. However, it is important to be cautious when wearing the contact lenses that you DO NOT sleep wearing them. Late night parties can be tiring but forgetting to remove your lenses can be dangerous for your eyes. 

Another caution while using contacts is checking its expiry date. Using expired contact lenses can gravely harm your eyes. To understand why you should not sleep with your contact lenses and why you shouldn’t ignore the expiry date, OnlyMyHealth integrated with Dr Rashmi Mittal, Consultant Ophthalmology, Amrita Hospital, Faridabad.

Dr Rashmi Mittal emphasises, “The eye is a delicate organ, and contact lenses, though beneficial, can pose risks if not used correctly. Proper lens hygiene and adherence to wear schedules are crucial to prevent infections and other complications.”

The Risks of Sleeping with Contact Lenses

One of the most dangerous habits among contact lens users is sleeping with their lenses still in. Unless specifically designed for overnight wear, contacts should be removed before bed. “Sleeping with contact lenses restricts the amount of oxygen that reaches the cornea, the clear front surface of the eye,” explains Dr Mittal. “This oxygen deprivation due to contact lenses can lead to corneal hypoxia, a condition that can cause blurred vision, discomfort, and in severe cases, permanent damage,” she further added.

According to studies, when contact lenses are worn overnight, they can also trap bacteria against the surface of the eye. This environment is ripe for infections, such as microbial keratitis, a serious condition that can cause pain, redness, and even permanent vision loss if not treated promptly. Dr Mittal warns, “Corneal ulcers are a common consequence of prolonged lens wear, particularly when sleeping with contacts. These ulcers can be extremely painful and require immediate medical attention.”

Furthermore, sleeping in contact lenses can exacerbate dry eye syndrome. Contact lenses absorb moisture from your eyes, and extended wear can lead to a significant decrease in tear production. This results in discomfort, irritation, and an increased risk of infection.

The Importance of Adhering to Expiry Dates

Ignoring the expiry dates on contact lenses is another common yet hazardous practice. Over time, expired lenses can accumulate deposits of proteins and lipids from your tears. These deposits can cause irritation, increase the risk of infection, and lead to allergic reactions. “Expired contact lenses are more than just outdated—they become a breeding ground for bacteria and other pathogens, putting your eye health at serious risk,” says Dr Mittal.

The optical quality of contact lenses also deteriorates after their expiration date. This can result in blurry vision or other visual disturbances, which can be dangerous, especially when driving or performing tasks that require clear vision. Dr Mittal adds, “Using expired lenses can compromise your vision and overall eye health. It’s vital to follow the manufacturer’s guidelines and replace lenses as recommended.”

Best Practices for Contact Lens Care

To protect your eyes, it’s essential to follow proper contact lens care routines. Start by always washing and drying your hands before handling your lenses. Regularly clean and disinfect your lenses with the appropriate solution, and never use water or saliva as substitutes. Adhere to the recommended wearing schedule and dispose of disposable lenses as instructed by the manufacturer.

“Your eyes are irreplaceable,” Dr Mittal reminds us. “By following these simple steps and being mindful of your contact lens habits, you can enjoy clear, comfortable vision without compromising your eye health.”
