Contact lenses can correct vision, offering convenience and clear vision without glasses. However, improper use can harm your eyes. Potential complications include infections, corneal ulcers, and vision loss. To protect their eyesight, individuals should consult an ophthalmologist, maintain hygiene, and replace lenses as recommended. Avoiding these contact lens mistakes is also crucial.

Overwearing lenses is a common mistake. Whether daily disposables, bi-weekly, or monthly lenses, each type has a specified lifespan. Wearing old or worn-out lenses not only causes discomfort but also increases the risk of bacterial buildup, scratches, and infections.

Wearing contact lenses in excessively dry environments, such as high altitudes or heated indoor spaces, can cause discomfort and reduce oxygen flow to the eyes. Similarly, wearing lenses while swimming increases the risk of infection due to potentially harmful microorganisms in pool water.

Sleeping in contact lenses is not recommended. It reduces oxygen supply to the eyes and disrupts tear exchange, creating a breeding ground for bacteria. This habit can lead to bacterial keratitis (corneal inflammation).

Neglecting lens hygiene or using tap water, unclean water, or expired solutions to rinse lenses can introduce harmful microorganisms like acanthamoeba. This single-celled parasite can cause severe keratitis, blindness, and even amoebic encephalitis (brain inflammation).

Touching lenses with dirty or wet hands can transfer germs directly to the eyes, increasing the risk of infections, irritation, or serious eye conditions like keratitis. Washing and thoroughly drying hands and using only recommended lens cleaning solutions are essential for maintaining healthy vision and preventing complications.

Clean lenses can still become contaminated if stored in a dirty case. Old solution, dirt, and a humid environment create a breeding ground for bacteria. Replace your lens case every 3 months, even with regular cleaning.
