  Wenzhou Wanrun Glasses Co., Ltd. is here to let you know! Here we would like to mention a parameter used to measure the Abbe number sharpness of the lens. The higher the Abbe number, the clearer the imaging. The lower the Abbe number, the more blurred the image. The higher the refractive index of the lens, the lower the Abbe number. Abbe number is mainly determined by the lens material itself. Some brands will use auxiliary additives to optimize Abbe number when making lenses.


  At present, there are also a few lenses on the market that can almost give consideration to Abbe number and refractive index. The Abbe number of ophthalmic optical lenses is usually between 30-60. The Abbe number of a common brand lens with a refractive index of 1.50 is about 58, and the Abbe number of a lens with a refractive index of 1.74 is about 32. The difference between Abbe number 58 and 32 is obvious, but the difference between Abbe number 40 and Abbe number 50 is small


  If your degree is high: you can give priority to thin and light effects, and choose lenses with high refractive index, but not too much. If the myopia degree is low: you can match a higher ampere multiple. After all, good visual effect is the king. The article comes from the network.
