Sunglasses Lenses and Function

When it comes to sun protection for your eyes, several types of sun lenses have different benefits to meet your specific needs.

Sunglasses with tinted lenses are a fashionable and effective way to shield your eyes from the sun. You can also have a graduated tint, which starts dark at the top and gradually lightens towards the bottom of the lens, making your lenses both practical and fashionable. Tinted lenses can assist restore natural color perception while also protecting your eyes from UV rays and boosting your eyesight.

Choose from a variety of colors, including brown, grey, grey/green, and burgundy, for a pair of sun lenses that provide comfortable, shielded vision while also appearing stylish. They function by dimming the sun’s brightness while preserving clarity and contrast.

Risks of Uv Light on Vision

UV exposure varies based on where you are, what you are doing, and what time of day or year it is. UV exposure, for example, increases as you get closer to the equator, and it also increases when the sun is high in the sky, which is normally between 10 a.m. and 2 p.m.

UV exposure is more common in open areas, especially near highly reflecting surfaces. Did you know that if UV rays are reflected off snow, your UV exposure might double?

If you are out in the bright light, even if the UV level is only 2 or less, you should still wear sunglasses. Overexposure can cause eye problems that could have been avoided if the proper precautions had been taken, just as if you went out in the sun without wearing sunscreen.
