Contact Lenses are a discreet way of managing vision impairments without being dependent on glasses. Many optometric patients choose contacts for the convenience and cosmetics. There are two classifications of contacts-soft and hard. Soft lenses are the most popular and are most commonly used to treat people with presbyopia, astigmatism, nearsightedness or farsightedness. They form to the shape of the eye and tend to stay in place for the duration of wear. Hard lenses although not as common as they once were, are still a good option for some patients.
