Standard plastic CR39 lenses for trifocal vision distance viewing also include tinted Polarization technology, making them great for outdoor activities on the water where there is a lot of glare reduction needed.  "Trifocal" 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 standard CR39, flat top 28 trifocal has a reading area that is 28mm wide at the top.  This is a good choice for prescriptions up to +/-3.00 sphere; above that, we would recommend a higher index lens in order to reduce the thickness and weight of the lens.  This lens is available in the following range: -6.00 to +3.00 sphere, -4.00 to +3.00 cylinder, and up to +3.00 add (prism and slab off excluded).
