"You’re not going to get this with contact lenses, whether or not they have transitions." They "block vertical rays of light and only allow horizontal rays of light to come in that is what enhances the quality of vision with sunglasses," Goel told BuzzFeed News. Polarized sunglasses block the reflected light from flat surfaces (like water), which can be too intense for the eyes. UV 400 glasses block both UVA and UVB radiation, or about 99.9% of UV rays. Ravi Goel, an ophthalmologist and clinical spokesperson for the American Academy of Ophthalmology. The best way to protect the eye from UV radiation is to wear wraparound sunglasses that are polarized and have UV 400 protection, said Dr. "As a reminder, we recommend patients continue to wear sunglasses for the highest possible protection from UV light." "We have not yet studied whether they would have an impact on the onset and severity of cataracts or macular degeneration," Lorenson said. UV rays can cause: cataracts, which is a clouding of the eye lens macular degeneration, which is a loss of central vision that is the leading cause of blindness and growths on the conjunctiva, which is the membrane that covers the surface of the eye and lines the eyelids. "In clinical studies, we have not received any feedback that the lenses interfere with viewing screens."īut it's also unclear if they can protect your eyes from ultraviolet light, so you'll still need to wear sunglasses with UV protection. "These contact lenses respond primarily to UV light and do not absorb substantial blue light in the non-activated (clear) state," said Lorenson. They shouldn't interfere with your ability to view blue light–emitting devices, like phones and computers. The lenses will be available in early 2019, according to the company, and the cost is not yet available.
“These should fade back pretty quickly," she said. If you have lighter-colored eyes, however, you might notice a slight gray tint.Īnd although glasses can take some time to fade back to clear, that shouldn't happen with these contact lenses, Lorenson said. Lorenson said that on brown eyes, the contact lenses should be almost imperceptible. However, you may notice them if you have lighter-colored eyes. "The results of the study demonstrated there was no evidence of concerns with either driving performance or vision while wearing the lenses," according to the FDA.
BLACK LIGHT COLOR CONTACTS TRIAL
The approval was based in part on a clinical trial of 24 people, which showed that the contacts didn't interfere with driving either at night or during the day. “This contact lens is the first of its kind to incorporate the same technology that is used in eyeglasses that automatically darken in the sun,” said Malvina Eydelman, director of the Division of Ophthalmic and Ear, Nose and Throat Devices at the FDA's Center for Devices and Radiological Health, in a statement. Those type of glasses, which rely on photochromic technology, have been around since the 1990s. The contact lenses are similar to "transition" glasses that get darker in strong sunlight but fade back to clear when inside. The Food and Drug Administration just approved contact lenses that contain a "photochromic additive," which gets slightly darker when you are out in the sun, and then becomes clear again.
