How Do I Know If Sunglasses Have UV Protection?
Sunglasses are an essential summertime accessory. They protect your eyes from the sun’s harmful rays and can help you see better in bright light. But how do you know if sunglasses have UV protection? Not all sunglasses are created equal, and some pairs don’t offer any UV protection at all.
Here are a few ways to tell if your sunglasses have UV protection:
The Label
The easiest way to tell if your sunglasses have UV protection is to check the label. The label should say “100% UV protection” or “UV400 protection.” This means that the sunglasses will block 100% of the sun’s harmful UV rays.
The Tint
The tint of the sunglasses can also give you a clue about whether or not they have UV protection. Darker lenses tend to offer more UV protection than lighter lenses. However, it’s important to note that the darkness of the lenses is not always an indication of UV protection.
The Price
The price of the sunglasses can also be a factor in UV protection. Generally speaking, more expensive sunglasses will offer better UV protection than cheaper sunglasses. However, there are some affordable sunglasses that offer excellent UV protection, so don’t be afraid to shop around.

Consequences of Wearing Sunglasses without UV Protection
Wearing sunglasses without UV protection can have a number of negative consequences for your eyes. These include:
- Sunburn on the eyes
- Cataracts
- Macular degeneration
- Pinguecula and Pterygium
- Eye cancer
Sunburn on the eyes, also known as photokeratitis, is a painful condition that occurs when the cornea, the clear outer layer of the eye, is damaged by UV rays. Symptoms of photokeratitis include pain, redness, tearing, and difficulty seeing.
Cataracts are a clouding of the lens of the eye. They can cause blurred vision, glare, and difficulty seeing at night. Cataracts are a common cause of blindness in older adults.
Macular degeneration is a condition that affects the macula, the part of the retina that is responsible for central vision. Macular degeneration can cause blurred vision, blind spots, and difficulty reading and driving.
Pinguecula and pterygium are non-cancerous growths on the conjunctiva, the clear membrane that covers the white of the eye. They can cause irritation and redness.
Eye cancer, including melanoma, is a rare but serious condition. It can occur in any part of the eye, including the eyelids, conjunctiva, iris, and retina.
Protecting Your Eyes from UV Rays
The best way to protect your eyes from UV rays is to wear sunglasses that offer 100% UV protection. When choosing sunglasses, look for a label that says “100% UV protection” or “UV400 protection.” You should also consider the tint of the lenses and the price.
In addition to wearing sunglasses, you can also protect your eyes from UV rays by:
- Wearing a hat with a brim
