You should choose sunglasses that offer 100 percent protection from UVA and UVB rays.
Polycarbonate lenses and other high-refractive plastics such as Trivex offer 100% UV protection.
Sunglasses are essential for summer outings. Not only do they add style to any look, but they also protect your eyes. Since their invention in 1752 by English optician James Ayscough, sunglasses have evolved significantly in both technology and design. Despite their wide availability, it is important to choose sunglasses that effectively protect your eyes from harmful UVA and UVB rays. Sunglasses without this protection are not only useless, but can also be harmful to your eyes.
Dr. Mahyar “Max” Maddahali recently posted a video on Instagram explaining the potential dangers of wearing sunglasses that do not have UVA and UVB protection. He stressed that “cheap” sunglasses that do not block these rays can damage the retina and sclera. According to the doctor, wearing low-quality sunglasses can lead to problems such as blurred vision, reduced vision, and even pinguecula, which is characterized by yellowish spots on the whites of the eyes. He also mentioned that it is important to choose sunglasses that provide adequate UVA and UVB protection to effectively protect eye health.
In the caption of the video, the doctor wrote: “Solar retinopathy is a condition that occurs when the retina is damaged by staring at the sun or other bright lights for too long without protection. This can lead to blurred vision, blind spots, or even permanent vision loss.”
Dr. Inna Ozerov, an ophthalmologist, told the Miami Eye Institute that in addition to choosing glasses that block radiation, you should also choose glasses with a larger frame. She explains, “When someone wears sunglasses, the pupils naturally dilate to let more light into the eyes. If the frame is not large enough, the UV light gets past the edges of the lens and can enter the eye more easily when the pupil is dilated.” Interestingly, the color of the lenses, whether red, gray or black, does not matter when it comes to blocking radiation.
