The Trivex bifocal lenses for reading and distance vision viewing means that the reading area has a half moon shape with a "flat top", in the bottow area of the lens.  The standard polycarbonate, flat top 28 bifocal has a reading area that is 28mm wide at the top.  The Trivex material is a good alternative to polycarbonate lenses in certain circumstances.  Trivex material has a higher ABBE value than polycarbonate, which offers similar strength as polycarbonate, but with less distortion ("chromatic aberration").  This lens is available in the following range: -8.00 to +4.00 sphere, - 3.00 to +3.00 cylinder, and up to +3.00 add (prism and slab off excluded).

This lens is also available in the Flat Top 35 style.  For the Flat Top 35 stye, the reading section is 35mm across thte top. After you have selected this lens, you will see the Flat Top 35 Upgrade option and the Executive Bifocal Upgrade option that you can then select.
