When is chromatism noticeable?

Spectacle lens chromatism

Chromatism is the name of the rainbow coloured fringes seen around high contrast borders. These become more noticeable when a person looks away from the centre of lens, especially in high powered lenses.

The website linked here has a worksheet you can use to calculate the distance from the lens centre where patients will notice chromatism in high powered lenses.

TIP: Print and photocopy these forms for making the Clinically Noticeable Chromatism in your eye-care practice.
