Contacts are a common and convenient way to correct vision problems such as nearsightedness, farsightedness, and astigmatism. They are small, thin lenses that are worn directly on the surface of the eye. Contacts are made from a variety of materials, such as soft plastics, silicone hydrogels, and rigid gas permeable (RGP) materials.

The first step in getting contacts is to visit an eye doctor. During the visit, the doctor will examine your eyes and determine the type and degree of your vision problem. They will also measure the curvature of your eye and the size of your cornea. This information is used to determine the type and size of contacts that are best for your eyes.

Once the doctor has determined the right contacts for you, they will teach you how to insert, remove, and care for your contacts. It is important to follow the instructions carefully to avoid infection and other complications.

When wearing contacts, it is important to practice good hygiene. This includes washing your hands before handling your contacts and cleaning the lenses daily with a contact lens solution. You should also avoid wearing your contacts for too long and replace them as recommended by your doctor.

Contacts can be a great way to correct vision problems and improve your quality of life. With proper care and maintenance, they can be a safe and effective way to improve your vision.
