SETO 1.60 Photochromic blue block Lens HMC/SHMC

Index 1.60 lenses are thinner than Index 1.499,1.56 lenses. Compared to Index 1.67 and 1.74, 1.60 lenses have higher abbe value and more tintability.blue cut lens effectively blocks 100% UV and 40% of the blue light, reduces the incidence of retinopathy and provides improved visual performance and eye protection, allowing wearers to enjoy the added benefit of clearer and shaper vision, without altering or distorting color percepyion.An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun's harmful UVA and UVB rays.

1.Characteristics of index 1.60 lens ①Higher impact resistance to scratches and impact ②1.60 lenses are about 29% thinner than the normal middle index lens and are about 24% lighter than 1.56 index lenses. ③High index lenses are much thinner due to their ability to bend light. ④As they bend light more than an ordinary lens they can be made much thinner but offer the same prescription power lenses.2.What blue cut lens to protect our eyes? The blue cut lenses cut down the harmful UV rays completely along with a major portion of HEV blue light, protecting our eyes and the body from potential danger. These lenses offer sharper vision and reduce the symptoms of eyestrain that are caused by a prolonged computer exposure. Also, the contrast is improved when this special blue coating reduces screen brightness so that our eyes face minimum stress when exposed to blue light. normal lens is good at blocking out harmful UV light from reaching the retina. However, they can’t block blue light. Damage to the retina can increase the risk of developing macular degeneration, which is a leading cause of blindness. Blue light can penetrate the retina and possibly lead to macular degeneration-like symptoms and may increase the risk of developing cataracts. Blue cut lens can help prevent this.3.The color change of the photochromic lens ① sunny day: in the morning, the air clouds are thin and the ultraviolet light is less blocked so the lens color changes darker. In the evening, ultraviolet light is weak because the sun is far away from the ground with the addition of the accumulation of fog blocking most of the ultraviolet light so the discoloration is very shallow at this point. ②cloudy day: ultraviolet light is sometimes not weak, but also can reach the ground, so the photochromic lens can still change color. The photochromic lens can provide UV and anti-glare protection in any environment, adjust the lens color according to the light in time while protecting the vision and providing health protection for the eyes anytime and anywhere. ③Temperature: under the same conditions, as the temperature increases, the photochromic lens will gradually become lighter; Conversely, as the temperature drops, the photochromic lens slowly becomes darker.4. What is the difference between HC, HMC and SHC？
       Hard coating     AR coating/Hard multi coating        Super hydrophobic coating
makes the uncoated lens hard and increases the abrasion resistance increases the transmittance of the lens and reduces surface reflections makes the lens waterproof, antistatic, anti slip and oil resistance
