What lenses do you use?

Our standard single vision lenses are a plastic material called CR39.  Our thinner lenses are also plastic but a denser material with an index of 1.56.  Our thinnest possible lenses are 1.67 index.

All lenses come with a scratch resistant coating free of charge.

We do not use glass lenses as plastic lenses are lighter, safer and with less risk of breakage.
