Crystal Vision Trifocal Trivex Lenses

Trivex Trifocal lenses are good for people with an active lifestyle and the most common prescriptions. Particularly good for rimless drill mounts and semi-rimless frames.  Trivex provides 100% UVA and UVB protection.  Trivex lenses for trifocal vision distance viewing means that the reading area has a half moon shape with a "flat top", in the bottom area of the lens.  The trifocal lens has three viewing areas, and the magnification area has two viewing areas, one for reading and one for intermediate distance.  The Trivex flat top 28 trifocal has a reading area that is 28mm wide at the top.  This is a good choice for prescriptions over to +/-6.00 sphere.  This lens is available in the following range: -6.00 to +4.00 sphere, -5.00 to +2.00 cylinder, and up to +3.00 add (prism and slab off excluded).

Trivex material has a higher ABBE value than polycarbonate, which offers similar strength as polycarbonate, but with less distortion ("chromatic aberration").
