How Long Can You Wear Contact Lenses: The Complete Guide to Eye Health

This is the first and most common sign of over-wearing. When you wear lenses for too long, the lens absorbs natural moisture from the eye, leading to dryness, burning, itching, and the sensation of "sand" in the eye. In some cases, this can develop into chronic dry eye syndrome, which requires special treatment.

Oxygen deprivation and debris buildup on the lens can cause noticeable eye redness. Your eyes look tired, irritated, and may even tear excessively in an attempt to compensate for the dryness. This is your eye's way of signaling that it's in distress.

One of the most dangerous risks is eye infection. Contact lenses, especially when worn too long or not cared for properly, can become a breeding ground for bacteria, viruses, and fungi. These infections can range from mild inflammation (like conjunctivitis) to corneal ulcers, a serious condition that can cause irreversible vision damage and even blindness in extreme cases.

When the cornea doesn't receive enough oxygen, it can swell – a condition called corneal edema. This can cause blurred vision, light sensitivity, and pain. In severe cases, chronic edema can lead to the growth of new blood vessels in the cornea, a phenomenon that can interfere with vision and prevent lens wearing in the future.

• Sudden pain or severe discomfort. Acute or persistent redness. Blurred vision. Light sensitivity. Eye discharge.

If you experience any of these signs, remove the lenses immediately and see an optometrist or ophthalmologist.

This is the most important rule. Always, and we mean always, wash your hands thoroughly with soap and water and dry them with a clean towel before touching your lenses or eyes. Bacteria on your hands are the number one cause of infections.

Only quality multipurpose solution designed specifically for contact lenses can clean, disinfect, and store your lenses. Never use water, saliva, or solutions not intended for this purpose. Pay attention to the expiration date of the solution and replace the bottle regularly.

Even if you feel comfortable, try to remove your lenses for at least a few hours a day, preferably in the evening before bed. If you work long hours at a computer or are in a dry environment (air conditioning, heating), consider removing the lenses for an hour or two during the day, or wearing glasses instead.

If you suffer from mild dryness, special eye drops designed for contact lens wearers can greatly ease the feeling. Make sure to choose drops that are suitable for use with lenses.

Even if you feel great, regular visits to an optometrist are essential. They can ensure that the lenses fit your eyes properly, check corneal health, and identify potential problems early on.

Never expose your contact lenses to water – not in the shower, not in a pool, not in the sea, and not at the tap. Water, especially tap water, contains microorganisms that can cause very serious infections. If you must swim, use a completely sealed swim goggle.

Each and every one of us has different eyes with unique characteristics. What works for a friend may not work for you. Therefore, individualized contact lens fitting is critical. An optometrist will perform a comprehensive examination and recommend the type of lens, curve, and material that best suits you.

Also, if you're unsure which shade of color lenses would suit you perfectly – one that will highlight your eyes' natural beauty and complement your skin tone – we invite you to take advantage of our personal consultation services. You can also try our special questionnaire to find the perfect shade: FANCY LOOK Color Lens Fitting Questionnaire.

Following these tips will allow you to enjoy a safe, comfortable, and pleasant contact lens wearing experience and maintain healthy eyes for years to come.

In short, generally not. Most contact lenses are not designed for sleeping. Sleeping with contact lenses dramatically increases the risk of serious infections and other eye problems, as it significantly reduces oxygen supply to the cornea and prevents the eye from cleansing itself. There are specific types of contact lenses approved for extended sleep (Extended Wear), but these require approval and fitting by an optometrist and are not sold at FANCY LOOK. The general recommendation is to remove your lenses before sleeping.

If you feel dryness, irritation, or discomfort, remove your lenses immediately. If the feeling doesn't go away after a few minutes, clean your lenses thoroughly and put them back on, or switch to glasses temporarily. You can also use special eye drops designed for contact lens wearers, called "artificial tears." If the irritation persists or worsens, see an eye doctor immediately.

You should replace the cleaning and storage solution in your lens case every day, even if you didn't wear the lenses that day. Never top up fresh solution over old solution; instead, empty the old solution, rinse the case with fresh solution (not water!), and refill it with new solution. It's also recommended to replace your lens case every one to three months.

It's not recommended. Exposing contact lenses to water (pools, ocean, shower) can expose your eyes to dangerous bacteria, including Acanthamoeba, which can cause very serious corneal infection. If you must swim with lenses, use a completely sealed swim goggle and remove your lenses immediately afterward, clean them thoroughly, or discard them (if you're using daily lenses). For annual lenses, the recommendation is to avoid exposure entirely or to clean and disinfect very thoroughly in case of water exposure.
