kontaktlencsére

Kontaktlencse, often referred to as contact lenses, are thin, curved lenses worn directly on the surface of the eye to correct vision problems. They are a popular alternative to eyeglasses for many individuals. Kontaktlencse can correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia.

The primary function of a kontaktlencse is to bend light rays so they focus properly on the retina, producing a clear image. They achieve this by altering the eye's overall refractive power. Materials used in kontaktlencse vary, with soft lenses made from hydrogel or silicone hydrogel being the most common due to their comfort and oxygen permeability. Rigid gas-permeable (RGP) lenses are also available, offering excellent clarity and durability, though they may require an adaptation period.

Proper hygiene and care are crucial for the safe use of kontaktlencse to prevent eye infections and irritation. This typically involves daily cleaning and disinfection with specific solutions, and following prescribed wearing schedules. Daily disposable lenses offer a convenient option, eliminating the need for cleaning. Regular eye examinations by an eye care professional are essential to ensure the continued suitability of the chosen kontaktlencse and the health of the eyes.
