Anti-glare, also known as non-glare, is a lens treatment that reduces the amount of excess light that comes through the lens causing unwanted glare. With an anti-glare treatment, the amount of excess light can be reduced by up to 99% resulting in clearer and more relaxed vision.
Anti-glare lenses also have additional features based on the quality of the lens treatment. These features include enhanced scratch and smudge resistance, the ability to repel water and dust, and premium UV protection. Some non-glare lenses also include additional blue light protection.
In recent years it has been discovered that there is a portion of the blue light spectrum that is believed to be unhealthy for our eyes. Blue light lenses afford the wearer with protection against the portion of the blue light spectrum that is believed to be the most harmful.
While the largest producer of blue light is the sun, we also encounter it in large parts thanks to our electronics. Exposure to blue light has been known to cause eye strain and fatigue, headaches, and even disrupt our sleeping schedule.
In today's market there are lots of ways to get blue light protection in glasses, including certain anti-reflective coatings, Transitions lenses, and special blue light blocking materials that reduce our exposure. As a result, many wearers see a reduction in their eye strain and fatigue, headaches and improve sleep schedules.
Transitions, generically known as photochromic lenses, are lenses that change color when exposed to UV light. Transitions lenses can help add comfort to the wearer when exposed to bright lights. These lenses adapt to the light creating a variable response based on exposure. Translation: the lenses are as dark as they need to be when they need to be giving the wearer a comfortable experience.
When choosing sunglasses, it is not only important ensure that the lenses protect against UV exposure but that they also protect against the sun's glare. When light rays hit surfaces all around us, those rays often reflect right back into our eyes. Polarization helps reduce the amount of light that is reflected back at us and into our eyes by filtering out those rays.
In addition to reducing the glare, polarized lenses also increase visual clarity, reduce eye strain, and in some situations may help reduce the likelihood of headaches due to light sensitivity.
