Suggestions on lens Purchase

 Good lens, the material is the key, a pair of High Index Lenses Meaning material, lens transmittance, durability and abbe number (lens surface rainbow pattern visual effect) and other properties play a decisive role. It can carry out in-depth research and development on materials, with controllable quality and excellent performance. Film layer, make the Transition Lenses easy to wear, good lens film layer, can give the lens more excellent performance, not only light transmittance and other optical properties have been greatly improved, its hardness, wear resistance, durability will be greatly improved.

Test the transparency and optical uniformity of the Eyeglasses Transition Lenses. Hold the lens and observe the distant scenery through the lens at a distance of about 30 cm from the front of the eye. If the scenery is clear without deformation and there is no scene jumping when the Transition Mirror Lenses is moved slowly, the transparency and optical uniformity of the lens are good.
