There are 4 different types of coloured contact lenses:
opaque colour tints, light-filtering tints, visibility tints and enhancement tints.
They work just like ordinary ones including correcting astigmatism where rays of light could not converge into a single focal point onto the retina.
Visibility Tints
Visibility tints are usually blue or green in colour and you can easily distinguish them from gravels once on the ground. It is a very light tint and does not affect eye colour.
Enhancement Tint
As the name implies, enhancement tints can change the colour of your eyes. They are meant for people who have light coloured eyes. They are solid and a bit darker than visibility tints.
Coloured Tints
Colured contact lenses come in a variety of colours: hazel, green, blue, violet, amethyst and grey. Due to the popularity of naturalness, coloured tints manufacturers have replicated the coloured portion of the eye. Since this area is made up of a series of colourful shapes and lines, the tiny coloured dots ont he lens blends in with the eye. The center of the lens, the part over your pupil, is clear so you can see.
Light-Filtering Tint
Seeing your target is absolutely crucial in sports. Quick reflexes are needed to manipulate a tennis ball with your racquet or dodging a jab from a boxer, and they all start from having good eyesight. To help you focus so that your target stands out from the background colour, light-filtering tints are used. They enhance certain colours (such as optic yellow, the colour of tennis balls, softballs and golf balls), while muting other colours.
