Contact lenses are worn by many individuals throughout the globe, particularly those who lead a lifestyle that is active and wants sharp, clear vision without having to wear specs. The majority of people can wear contact lenses and benefit from the independence of not needing glasses to see.

Types of Contact Lenses: 

Soft contact lenses and rigid gas permeable contact lenses are the two most important types of contact. Soft contact lenses are extremely thin and very comfortable to use. They are soft because they are completely composed of water. 

Spherical that are normal contact lenses, contact lenses that are used for astigmatism, contact lenses that are used for presbyopia, and coloured contact lenses that are used as cosmetic contacts are the four most primary types of soft contact lenses. 

Rigid gas permeable contact lenses are comprised of hard plastic and provide sharp, clear vision while correcting the majority of vision issues. They are more robust than soft contact lenses and last far longer.
