Colored contact lenses are available in toric, bifocal and disposable types. Actually, colored contacts use three types of tints: visibility tint, enhancement tint and color tint. Light blue or green visibility tints are used to make contacts more apparent while you putting them on or removing them off. Unlike a visibility tint, an enhancement tint intensifies your eye color slightly using darker colors. They are solid and meet the need for some people. Color tints are favored by people with dark eyes but want to change their eye color. These deep colors used include hazel, green, blue, violet and grey. Costume or theatrical contacts belong to this type, which always create special effects in novelties and movies by changing the people’s natural eye color. For all these three tint types, natural appearance is the most important code. Some manufacturers even make tiny colored dots on lens without affecting the lens center.
