Eyeglasses and sunglasses are both used to protect your eyes from the sun. But there are a few differences between the two:
- Eyeglasses have lenses that sit in front of your eyeballs, while sunglasses have lenses that sit on top of them. This makes it easier for you to see through your glasses when you’re wearing them.
- Eyeglasses are designed to correct your vision. They are corrective lenses that help make your eyesight clearer or sharper. You wear them over your eyes and they rest on your ears.
Sunglasses are another type of corrective lens, designed to protect your eyes from harmful UV rays. They are usually made of plastic or polycarbonate, which is why some people call them “plastic glasses” or “plastic shades.” They protect the eyes from sun damage, windburn, snow glare, and other environmental factors that can cause damage to the retina or cornea of the eye.
Sunglasses will protect you from UVA and UVB rays, but only if they meet the ISO 12312-2 certification requirements. You can check this by looking for the sticker on the inside of the frame or case. Glasses can be made out of many different materials, including plastic, metal, and even wood!
Sunglasses can also be made out of these materials—but they are usually made out of plastic or glass instead, because they’re more durable and less likely to break than wood or metal frames would be under normal use conditions (like if you drop them).
You can buy your glasses from reputable merchants who deal with designer eyewear San Diego-made. Always do thorough research before settling for a pair.
