These Contact Lenses Get Darker In The Sun
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.To get more news about colored contacts cheap, you can visit beauon.com official website.
The contact lenses are similar to "transition" glasses that get darker in strong sunlight but fade back to clear when inside. Those type of glasses, which rely on photochromic technology, have been around since the 1990s.
“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.To get more news about colored contacts for dark eyes, you can visit beauon.com official website.
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. "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.To get more news about Blue Contacts, you can visit beauon.com official website.
There’s not going to be any creepy alien eyes," said Donna Lorenson, a vice president in communications at Johnson Johnson Vision in New Brunswick, New Jersey.
Johnson Johnson makes the contact lenses, called the Acuvue Oasys contact lenses with Transitions Light Intelligent Technology. They are soft contacts made for daily wear up to 14 days. "We spent years figuring out how to do this," she told BuzzFeed News.
The company was unable to share any images of what the contact lenses actually look like on the human eye. But Lorenson said they did try to make sure they did not have a large impact on the eye's color.The lenses will be available in early 2019, according to the company, and the cost is not yet available. They shouldn't interfere with your ability to view blue light–emitting devices, like phones and computers.
"These contact lenses respond primarily to UV light and do not absorb substantial blue light in the non-activated (clear) state," said Lorenson. "In clinical studies, we have not received any feedback that the lenses interfere with viewing screens."
But it's also unclear if they can protect your eyes from ultraviolet light, so you'll still need to wear sunglasses with UV protection. 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.
