corneallens

Corneal lenses, also known as contact lenses, are thin, curved lenses worn directly on the surface of the eye, the cornea. They are primarily used to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. In addition to vision correction, some corneal lenses are used for therapeutic purposes, to protect the eye, or to improve its appearance.

There are two main types of corneal lenses: soft lenses and rigid gas-permeable (RGP) lenses. Soft lenses are made from flexible plastics containing water and are generally more comfortable to wear. RGP lenses are more rigid, allowing for better oxygen permeability and sharper vision for some individuals, particularly those with significant astigmatism. Both types require proper fitting by an eye care professional to ensure optimal vision and eye health.

Corneal lenses are typically worn daily and removed for cleaning and disinfection, or they can be designed for extended wear for a specified period. Proper hygiene practices are crucial to prevent eye infections and complications. Regular eye examinations are also necessary for contact lens wearers to monitor eye health and ensure the continued suitability of the lenses. Advancements in materials and design continue to improve the comfort, safety, and effectiveness of corneal lenses.
