The harm of ultraviolet light to the eye cannot be ignored. Scientific research has confirmed that intense sunlight is one of the major causes of cataract. A study by the Johns Hopkins University showed that 1 more hour of exposure to the sun per day will increase the risk of cataracts by 10% in one year, and that outdoor workers were 3 times more likely to develop cataracts. In addition, solar corneal endothelial damage is also one kind of eye diseases caused by UV light. Prevention of UV damage to humans and most importantly, to avoid long time activities in the strong sunlight. In addition, you can also use light colored umbrellas and cheap Oakley sunglasses to weaken the intensity of ultraviolet light. Ultraviolet light in the sun can cause damage to the lens of the eye, which can lead to degeneration of the lens and cataract. Prolonged exposure to intense light results in cataracts to form early. Apart from that, , the cornea tends to absorb most of the UV light which, as a result, will easier to lead to keratitis and conjunctivitis after exposure to intense sunlight. The best way to reduce UV damage to your eyes is to wear UV – resistant sunglasses. Best buy cheap real Oakley sunglasses from the regular glasses shop, on one hand, sunglasses with poor quality cannot effectively prevent ultraviolet radiation. On the other hand, due to the incorrect refractive power, it cannot be well adjusted and relax the eyes, which can cause visual fatigue, astigmatism, myopia and so on. In addition, the sunshade hat can, to some extent, play a role in shielding the strong sunlight. Those who wear contact lenses should be prepared with a pair of frames, glasses, spare parts, the required care solution and eye drops to ensure hygiene. For people who wear frame glasses, it is best to choose anti ultraviolet frame glasses.
(2) Recognition of ultraviolet light (UV);
Among the lights that reach the surface of the earth, the ray of light that the human eye can distinguish is 380nm-760nm, with the wavelength is ranges from 10nm to 380nm. Ultraviolet light is divided into UV-A, UV-B and UV-C according to different wavelengths.
Note: 1. due to the high concentration tinted lenses have lower transmittance than the average concentration, people’s pupil increased, if not added anti UV agent, ultraviolet light will get into easily the eye, and cause harm.
2. anti-UV special processed lenses cannot be used as welding glasses, laser and X-ray protective glasses.
Anti-ultraviolet lenses have been added with UV protection materials to prevent UV-B from entering the eye. A good UV isolation layer of fake Oakleys helps prevent UV-A from entering the eye and even transparent lenses has the function to protect against UV rays.
General resin lenses or knockoff Oakley sunglasses can not block out harmful ultraviolet rays completely, lenses processed by anti-UV material can isolate UV-A, UV-B and reduce cataract and keratitis.
The skin around the eye is delicate and easy to be damaged by the external stimulus. The use of anti UV TAG lens can reduce spots and wrinkles around it.
