Many different types of coloured lenses are available – everything from lenses which emphasise the natural eye colour to lenses which change the eye colour completely. Coloured lenses are available as daily disposables and monthly disposables, and just like traditional lenses, coloured lenses should also be tested at an optician’s. The colour result will vary from person to person depending on the eye colour. In order to achieve the desired effect, zero-prescription lenses should therefore also be tested at an optician’s.
