A contact lens is a thin, curved lens inserted directly onto the tear film, which covers the anterior surface of our eye. Patients wear them for a variety of reasons, including: visual correction, therapeutic or cosmetic reasons. Contacts are either hard, soft or a hybrid.
Aside from the obvious improved visual activities, or cosmetic enhancement, here are some the benefits of wearing contact lenses:
- Certain eye conditions such as keratoconus usually see increased visual correction with contacts, as compared to spectacles.
- They generally provide improved peripheral vision, as compared to glasses.
- They don’t “fog up” or collect moisture, as a pair of glasses would over a hot stove, or on a rainy day.
- Glasses can fall off or possibly become damaged during exercise or active lifestyles.
Patient education, hand washing, compliance with care and wearing schedule are some of the challenges that providers face in the care of CL patients even today. Many common care mistakes, including failing to clean and store lenses as directed by a doctor and sleeping while wearing contacts, can increase the chance of infection. So regular eye checkups are advised for all contact lens wearers.
