Jorgen, Germany.
I have a congenital visual impairment (achromatopsia) and have been wearing square-cut glasses for many years. However, due to stigmatization, it was always a problem for me to wear sunglasses in bright rooms. I looked around for contact lenses with edge filters and realized that there are very few suppliers with very high prices. By chance I became aware of Achrolenses and they tried very hard to find the right lenses together with me, sometimes even to develop them. Now I have a pair of indoor contact lenses with a custom made filter 527 and one outdoor with a custom made filter 550, for less money than a pair at the optician’s. In addition, the material of the lenses is ideal for dry eyes (I have often broken normal lenses). You can contact Achrolenses with any questions and they will try to find a solution.
