Clarification - do you have extremely high strengths such as a +20 or -20?
Whether for unifocal, progressive or bifocal lenses, the 'Vision Specials range' can accommodate your extremely high strengths. To achieve the nicest results, a lenticular lens is often incorporated into the glass. A lenticular lens is generally recognisable by a 'dimple' in the glass. With our Specials range, this striking cavity in the glass is now a thing of the past. There will still be a height difference, however, it will be nicely adjusted to your chosen frame. We call it an "invisible" lenticular lens, as if it "fades away" into your frame. We are happy to tell you that we provide not only the best visual comfort, but also the most aesthetic solution.
