Does Abbe Value Matter?

The Abbe value determines to a large part the optical integrity of the lens. The higher the abbe value the better the optical clarity and less distortion.

Is higher Abbe value better?

The higher the Abbe value, the better the peripheral optics will be. The lower the Abbe value, the more chromatic aberration will be a characteristic of that lens. ... Many plastic materials have Abbe values of roughly 58. Most high index plastic type materials have a lower Abbe value, some as low as 30.

What is a good Abbe number?

Most commonly used ophthalmic plastic lens materials have Abbe values between 30 and 58, the higher the number the better optical performance. Polycarbonate is the worst performing commonly used plastic, having the lowest value of 30. As a general approximation, material index vs.
