Contact Lenses
Contact lenses (also known simply as "contacts") are corrective, cosmetic, or therapeutic lenses usually placed on the cornea of the eye. Modern contact lenses were invented by the Czech chemist Otto Wichterle, who also invented the first gel used for their production.
Contact lenses usually serve the same corrective purpose as conventional glasses, but are lightweight and virtually invisible--many commercial lenses are tinted a faint blue to make them more visible when immersed in cleaning and storage solutions. Cosmetic lenses are deliberately colored for altering the appearance of the eye.
It has been estimated that about 125 million people use contact lenses worldwide.
People choose to wear contact lenses for various reasons. Many consider their appearance to be more attractive with contact lenses than with glasses. Contact lenses are less affected by wet weather, do not steam up, and provide a wider field of vision. They are more suitable for a number of sporting activities. Additionally, ophthalmological conditions such as keratoconus and aniseikonia may not be accurately corrected with glasses.
