how much is transition lenses cost
Transitions are a trade marked brand of photochromatic optical glasses lenses. Transitions Lenses UK - Photochromic Eyeglass Lenses & Sunglasses. In my practice (large multiple) they typically are Â£100 more than the standard lens alternative. Two reasons for the cost: 1  There is an additional step in the lens manufacturing process, where photochromatic material is absorbed into the surface of the lens - not throughout the whole lens but just under the surface. 2  The main reason for the large additional cost is the fact that Transitions is a premium brand. Other photochromatic lenses are on the market and are much cheaper, but you are paying for the brand and arguably the science and research the brand offers.
