Your typical prescription eyeglasses don’t provide sufficient protection from the harmful effects of the sun. However, just wearing sunglasses won’t give you sharp vision. Fortunately, there are glasses that can protect your eyes from ultraviolet rays while giving you clear eyesight.
Vision therapy specialist, Institute for Control of Eye Myopia in Children, discusses the difference between photochromic lenses and prescription sunglasses.
Photochromic lenses are clear indoors and darkened when hit by the sun. The lenses are activated by ultraviolet radiation from the sun and turn clear again after moving indoors. They are offered in various materials, lens colors and lens treatments. Transitions lenses can be used in prescription progressive and bifocal glasses.
What Makes it Different From Prescription Sunglasses?
Transitions lenses and prescription sunglasses eliminate the hassle of switching between sunglasses and eyeglasses. Children who wear eyeglasses will also benefit from glass that automatically adapts to different environments. Consult your vision correction specialist for lenses that are suitable for your child.
Both eyewear can block 100% of UVA and UVB rays. They can be used in most frames including ones from designer brands.
Photochromic lenses are great for short trips while prescription sunglasses are better for activities in the water or snow. Adaptive lenses may not react to glare from snow or water and can take longer to darken in colder temperatures. Prescription sports sunglasses may provide better impact resistance and comfort than prescription glasses with photochromic lenses.
While photochromic lenses adapt to changing light conditions, most don’t work in the car. This is because windshields already have filters that block UV rays. There are adaptive lenses designed for driving but aren’t recommended for nighttime use.
Protecting your eyes from the sun is important because UV rays can damage your retina and even cause cataracts. Visit your optometrist for an eye exam to determine the best eyewear for you. Contact a myopia control specialist near you today for more information on prescription eyewear.
