In order to provide you with a natural vision at any distance, all of your personal data, consisting of information on your eyes, your glasses and your spatial perception, will be compiled and adapted to the chosen frame. Data on prescription values, the best lens progression to suit your needs, your vision habits and your priorities are calculated, blended with the unique features of the Ysis design. All personal data, taken together, add up to your personal vision profile - the Ysis profile. The result: Ysis - your personal, natural vision, lenses. Following you can see two possible examples of an Ysis profile:
Example 1:
A woman in her late 20s is slightly near-sighted. Her PD (pupillary distance) measures 58 mm. The back vertex distance (BVD) is 13 mm.
Example 2:
A young woman tells her optician about her problems seeing at night. She has a PD of 65 mm and a BVD of 11 mm. The examination of her eyes in the dark refraction room shows an improvement of her visual acuity of -0,5 dpt. She also takes a further feature for her Ysis-lenses to improve her long-distance vision.
