Bifocal lenses made with the glass lenses material for bi-focal vision distance viewing means that the reading area has a half moon shape with a "flat top", in the bottow area of the lens.  The standard glass, flat top 28 bifocal 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: -5.00 to +3.00 sphere, -4.00 to +3.00 cylinder, and up to +3.00 add (prism and slab off excluded).  Crystal Vision Lenses are top quality lenses at a reasonable price point, and come with our Perfect Lenses Guarantee.
