One of the ways you can protect your eyes is to selectively filter the blue light around you so your eyes receive good light, while at the same time reducing your exposure to bad blue light. Some lenses can include a specialized filter to help reduce exposure to harmful blue light.

Light enters the eye through the cornea. This is the clear, dome-shaped surface that covers the front of the eye. From the cornea, the light passes through the pupil. The iris, or the colored part of your eye, controls the amount of light passing through.

The visible part of the eye is protected by the eyelids and the eyelashes, which help keep dirt, dust, and even harmful bright light out of the eye. Eyes are also protected by tears, which moisten them and clean out dirt, dust, and other irritants that get past the defenses of the eyelashes and eyelids.

Protect your eyes against the sun

1. Wear sunglasses year-round whenever you are out in the sun.
2. Choose shades that block 99 to 100 percent of both UVA and UVB light.
3. Wear a hat with at least a three-inch brim and tightly woven fabric (no holes) to protect your face and the top of your head.

The sun’s damage to the eyes does not stop with cataracts. Exposure to both visible light and UV radiation is also a factor in the gradual degeneration of the retina, damage to the cornea, and pterygium (an overgrowth of the conjunctiva).

Mirrored Sunglasses The lenses look shiny on the outside, kind of like you’re looking at a mirror (hence the name). Mirrored eyewear also keeps too much light from getting into your lenses, improves how well you see colors, and protects your eyes against ultraviolet (UV) light.

Wearing sunglasses can protect a person’s eyes from all these concerns. But not all shades are created equal. “It doesn’t matter how dark they are or the color of the lenses,” Taylor says. “The most important thing is that the sunglasses block 99 to 100% of UVA and UVB rays.”

Most sunglasses today have UV protection embedded in the lens rather than coated over it, and most reputable brands list UV protection on their label. Polarization has nothing to do with UV light absorption, but many polarized lenses are now combined with a UV-blocking substance.

Scaring people off wearing sunglasses will not protect their skin any more or any less.” Prolonged exposure to UV can cause a number of serious eye conditions, including the premature formation of cataracts, macular degeneration, pterygium (a growth on the eye) and photokeratitis (sunburned eyes).

If you have sunglasses on constantly, your eyes will miss some of the 1,500-some wavelengths that contribute to your eye health. Blocking too much sun impacts the entire body: Not only does constantly shielding the sun from your eyes impact your eye health negatively, but it also negatively affects the entire body.

Is it bad to wear your sunglasses all the time? Sure, most of us probably should wear sunglasses more often than we do — especially outdoors when we need to protect our eyes against damaging ultraviolet (UV) rays. However, wearing shades when you don’t need UV protection can damage your eyesight in the long run.
