Colored lenses. Many of the types of lenses described above also come in colors that can enhance the natural color of your eyes – that is, make your green eyes even greener, for example. Other colored lenses can totally change the color of your eyes, as in from brown to blue.
Contact lenses are placed directly on the surface of your eye to correct your vision.
They can correct short-sightedness (myopia) and long-sightedness (hyperopia). They can also correct astigmatism and age-related long-sightedness (presbyopia).
