Our skin gets more attention during this season than protecting one of the most precious parts of our body—the eyes. It’s better for us to discuss why we should take care of our eyes too. Just as how UVA and UVB destroys our skin, it also has an effect on our sight. Style matters less, but protection does. What’s more, UV damage is cumulative, so every time you step out in shades, you’re doing your eyes a favor — and staving off potential sunburn of the cornea (the eye’s outer layer) or conjunctiva (the layer that lines the eyelids), as well as preventing cataracts (clouding of your eye’s lenses) and macular degeneration (retinal damage that leads to vision loss). Here’s a brief friendly reminder for all.
What is the difference between UVA and UVB rays?
The sunlight that reaches us is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB). Basically, UVA rays can age us and UVB rays can burn us. Overexposure to either can damage the skin. There’s also a third type of ray, UVC – these are the shortest and strongest, but thankfully they’re absorbed by the ozone layer and don’t typically reach the Earth.
UVA rays penetrate deep into the dermis, the skin’s thickest layer. Unprotected exposure can lead to premature skin aging and suppression of the immune system. And when your skin’s defenses are down, you’re at risk for skin cancer.
The intensity of UVB rays vary by season, location and time of day, with 10AM to 4PM being the peak hours. Sunburned skin doesn’t just feel awful, it can cause permanent damage over time.
Is eye protection more important in summer than at other times of the year?
Just as how important SPF to us, wearing sunglasses should be worn all year long.
Are any sunglasses shapes better than others?
If you opt bigger frames like those of the Kardashians, you are doing yourself a good favor. Others wear sporty wraparound frames. Those are designed to allow the least amount of light to come through.
Can I get cheap $5 glasses from the sidewalk?
Would you believe some of those offer solid protection from UV? The downside of it is that cheap glasses have low quality lenses. You don’t want to distort your vision, don’t you? Additionally, the frames are usually made of cheap materials that they don’t hold up to normal wear and tear.
Is lens color important when it comes to blocking UV rays?
Color lens are actually just for personal preferences.Lens color doesn’t affect the ability to block UV. You can even wear a clear lens that has UV-absorbing properties.
What do “polarized” lenses do?
I use polarized lenses when I work on the computer because ‘Polarized Lenses’ are designed to reduce 100% of reflected glare. the kind of glare that comes off water, snow, road surface when driving or walking, and computer screens. Polarizing filters operate like venetian blinds — only allowing one direction of wavelength to pass through. You can now decide whether to choose between tinted lens or polarized ones.
Are darker lenses more protective?
Not always but darker lenses allow little light to pass through. There are people with certain eye disorders that may not need darker lenses.
