There’s more to eyewear than just looking stylish this summer! You also need to consider the importance of protecting your eyes from harmful UV radiation. So, let’s dive into the world of UV rays and learn about potential UV damage to eyes if you don’t protect them.
What types of UV rays affect your eyes?
Did you know that UV radiation comes in three forms? UVA, UVB, and UVC. Fortunately, UVC doesn’t reach our eyes as the earth’s atmosphere absorbs it, but UVA and UVB can harm our eyes if we continually expose our eyes to them over the years.
UVA can permanently damage our eyes in the long term by passing through the cornea to the retina at the back of the eye, while UVB is absorbed by the cornea on the surface, and can cause short-term damage like photokeratitis, which is essentially like having painful, sunburnt eyes.
Now, let’s get to the nitty-gritty. UV radiation doesn’t just cause our skin to age, because of its ability to penetrate your eyes, it can also increase your risk of developing serious eye conditions like macular degeneration and cataracts in later years, cause corneal damage, and even trigger eyelid skin cancer.
That’s why you must invest in top-quality eyewear with UV protection to protect your eyes against these conditions.
Sunglasses – UV protection
But not all sunglass lenses are created equal. Cheap knock-offs, especially those bought from market stalls or even ordered online, may look good with dark lenses but this doesn’t mean they offer UV protection. In fact, darker lenses without a UV filter cause our pupils to dilate, allowing more sunlight in, which is ultimately more damaging than helpful. That’s why you should always go for eyewear with sunglass lenses from authorised retailers like our Canning Town and Barking Opticians, as these are subject to strict regulations and offer 99-100% UV protection against UVA and UVB rays.
Polarised sunglasses with UV protection
Now, here’s something cool: if you opt for polarised lenses, you’ll also benefit from glare reduction. Glare reflects off horizontal surfaces like the road or water into our eyes, which can cause eye strain, make you squint, and even obscure your vision temporarily because it’s so bright.
So, getting sunglasses made up with polarised lenses is perfect for anyone who plays sports, drives a lot, or spends plenty of time outdoors. Coupled with a UV coating, polarised lenses offer greater comfort, clearer, high contrast vision, and improved depth perception, so you can enjoy the great outdoors to the max.
Photochromic glasses for UV protection
Did you know that there are glasses that react to light? Photochromic lenses are designed to safeguard your eyes from harmful UV rays when they darken to a sunglasses tint and are amazing for outdoor activities such as golfing, cycling, fishing, skiing, running and tennis.
When you go outside, the lenses automatically get darker, and fade back to clear quickly when you go back inside. The lenses can also react to darken to a slight tint even if it’s not super sunny, so your eyes can still receive that all important UV protection.
The change in tint is caused by photochromic molecules in the glasses. They react to UV light when exposed to it and turn the lenses dark. Photochromic glasses also stay clear indoors, which means you don’t have to switch between prescription glasses and sunglasses if you move indoors and outdoors a lot everyday.
Sunglass tints explained
Last but not least, let’s talk tints! These can be incorporated into your UV protection sunglasses to improve your clarity of vision in different light conditions. For cloudy days, yellow lenses provide increased contrast while brown and grey lenses give you more accurate colour perception, making them a great choice for driving.
