Contact lenses are thin, curved discs made of a breathable material that is placed directly on the surface of the eye. They are used to correct vision problems, providing an alternative to eyeglasses. Contact lenses can help correct refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and presbyopia.

Contact lenses work by refracting light as it enters the eye, helping to focus it properly on the retina for clearer vision. They offer several advantages, including a wider field of view, freedom from glasses, and compatibility with various physical activities.

Contact lenses come in different types, including soft lenses, rigid gas permeable lenses, toric lenses for astigmatism, multifocal lenses for presbyopia, and specialty lenses for specific eye conditions. They require proper cleaning, disinfection, and regular replacement to maintain eye health and optimal vision correction.

It is essential to consult with an eye care professional to determine the most suitable type of contact lenses for your specific needs, undergo a fitting process, and receive guidance on proper usage, care, and follow-up appointments to ensure the best comfort, safety, and visual outcomes.
