MIAMI, Fla.--BCD (Bristol Consulting & Development), based here is introducing Poly-B a series of semi-finished flat-top polycarbonate aspheric lens blanks.

“In the past, patients with high prescriptions that needed a high-index or poly lens were told they could not use a FT-28 or a light material, but instead had to go to a FT-22 or Round 22 in CR-39 [monomer from PPG] or even a lenticular design,” said Alex Bristol, Jr., president of BCD. “Now we are introducing polycarbonate aspheric flat top 28 SF 6-base, 10.50 base and 12.75 base lenses. The 6-base is available in 1.50-3.00D additions and the 10.50 and 12.75 are available in 2.00-3.50 and 4.00D additions. Together with our aspheric polycarbonate single-vision, which was introduced in early 2007 in 4, 6, 8, 10, and 12 bases, this gives your laboratory a prescription range up to +12.75 RX in SV and FT poly with a much thinner, flatter and lighter lens with hard coating and UV protection,” Bristol said.
