Contact lenses are medical devices. This means that when using them, you must follow all doctor’s prescriptions and instructions. Otherwise, the harm from wearing contact lenses may be more than good. Unfortunately, over time, many patients make mistakes that lead to the development of complications.
The most common mistakes are…
Mistake No. 1 Violation of the mode of wearing lenses
Most types of contact lenses cannot be worn all the time, let alone sleep in them. Wear time depends on various factors, including the degree of oxygen penetration and moisture content. Read the instructions carefully or ask your ophthalmologist about it. With a lack of oxygen, corneal hypoxia can develop. Hypoxia can lead to the formation of new vessels and their ingrowth into the cornea. If you ignore this condition and continue to wear lenses, it can cause serious visual impairment.

Follow the rules of hygiene, change the solution for disinfecting lenses in a timely manner, do not touch the lenses with dirty hands and do not wear them during SARS. Failure to comply with these rules provokes the development of inflammatory diseases, infections. Remember: if the infection becomes chronic, the lenses will no longer be worn at all. To correct your vision, you will have to use glasses again.
Mistake No. 3 Inaccurate putting on and taking off lenses
If the lens is damaged or you don’t put it on properly, you can damage the cornea of your eye. As a rule, this happens when using hard lenses. In the most unfavorable case, this will lead to the appearance of ulcers on the cornea.

The components of the solution can cause an individual allergic reaction, lead to keratitis or conjunctivitis. If you experience any discomfort, you should stop using lenses and contact an ophthalmologist.
