High Index

Does High Index material really make a difference in my prescription?

If your Rx is + or -4.00 or higher in the sphere power, it does make a difference. High index glass makes the lens thinner and lighter. This is for single vision only in your dive mask.

It does this by bending light waves in a slightly different angle than crown glass.

When mounting into a mask, the thickness can be an issue in higher prescriptions. We can make it work by applying a heavier bevel on the edges of the lens. Our motto is any prescription, any mask, but sometimes with a strong Rx is better to get a mid -volume mask.
