Contact lenses are thin, curved plastic discs placed directly on the tear film of your cornea to correct vision. Over 150 million people worldwide wear them as a safe, effective, and nearly invisible alternative to eyeglasses. Types of Contact Lenses
The type of contact lens an eye doctor prescribes depends entirely on your visual and medical needs.
Soft Contact Lenses: Made from flexible hydrogel plastics, these are the most popular lenses because they allow oxygen to pass through to the cornea and stay highly comfortable. Daily Disposables: Worn once and thrown away at night.
Daily Wear: Worn during the day, taken out at night to clean, and replaced every few weeks. Extended Wear: Specially made to be worn safely overnight.
Hard (Rigid Gas Permeable) Lenses: Made from firmer plastic, these offer sharper vision for specific conditions like severe astigmatism but take longer to get used to. Benefits of Wearing Contacts
Many people choose contacts over glasses to accommodate active lifestyles.
Natural Sight: They move with your eye, providing a wider field of view and better peripheral vision than glasses.
Sports Friendly: They will not slip, pinch, or break during physical activities.
Weather Proof: They never fog up in cold weather or collect raindrops. Proper Care and Safety
