Using new lenses can help reduce the incidence of eye diseases

Khalifa University researchers have produced a new type of lenses for eye protection, which change color according to changes in temperature and ultraviolet radiation, and also prevent the occurrence of eye diseases.

According to Tekna technology and technology news service, new lenses change their color in response to environmental changes and prevent the occurrence of eye diseases. Cataracts with clouding of the lens of the eye are one of the prominent eye diseases that bring 10 million people to the surgery room every year. One of the main causes of this type of eye disease, in addition to age and snow blindness, is exposure to ultraviolet rays. Researchers at Khalifa University in Abu Dhabi have developed advanced lenses to protect the eyes from UV rays. Photochromic and thermochromic powders are used in making this type of lenses.

Active or inactive modes of these lenses can provide unique optical features. According to researchers, in normal mode, this lens can remove about 45% of ultraviolet rays and block 20% of blue light in the environment. If this lens is exposed to ultraviolet rays, it will become darker and will absorb some visible light. According to the photochromic material used, the speed and intensity of the process of these lenses are also different. Therefore, users can custom-make their own lenses according to the amount of thermochromic and photochromic powders. These lenses are sensitive to temperature and with multi-purpose use, they can determine the conditions of disease in light changes.
