Contact lenses are small, transparent lenses placed directly on the eye to correct vision defects or for cosmetic purposes. Because they are positioned on the eye’s front surface, contact lenses offer a more direct vision correction than glasses. There are essentially two main types of contact lenses:
The main uses of contact lenses are as follows:
Used to correct vision defects such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
Toric (astigmatism correcting) lenses, in particular, can help correct astigmatism.
Multifocal or bifocal lenses can be used to correct age-related farsightedness.
Lenses with colors or different patterns can be used for cosmetic purposes.
Since wearing glasses during sports and other physical activities can be uncomfortable, many athletes and active individuals may prefer contact lenses.
Using contact lenses requires adherence to proper hygiene and care routines. Cleaning the lenses, following the recommended frequency of replacement, and regular eye exams are important. Your eye doctor can help you choose the appropriate type of lens, use your lenses correctly, and maintain your eye health.
