No one should be staring at a partial eclipse.Īlong those same lines, wouldn't looking at the sun setting-when brightness is down-also be bad? Unfortunately, the level of infrared radiation is still enough to burn your retina and cause a solar retinopathy . A partial eclipse is more dangerous to view as the absence of the bright sunlight would allow one to stare at the sun. In Philadelphia, we will experience a partial eclipse of about 75 percent. We have also learned that macular degeneration may be influenced by UV exposure.Īnything to add? Is there anything people should know?Ī solar eclipse will be visible in the U.S. This was determined by following a group of fishermen on the Chesapeake Bay. The most important thing we learned in the last few decades is that UV light is associated with cataract development. What is some knowledge we now know about UV rays and shielding our eyes that we maybe didn't a decade ago? Though sometimes children develop cataracts and you can develop them at a younger age. That’s when cataracts start to show up in people.
Interestingly, almost all cataract implant lenses include UV light filters.Īt what age do cataracts typically develop?
No. Actually, as we develop cataracts, they tend to absorb more of the blue spectrum of light. People tend to spend more time outside in the summer and therefore it is a greater concern.Īre our eyes more susceptible to damage from the sun's rays as we get older? What's the difference between the sugar substitutes?Īre UV rays more of a concern during summer months? And how much should we still be paying attention to this sort of thing during winter months?īecause the angle of the sun and duration of sunlight is greater during the summer in the northern hemisphere, there is more UV light exposure during this season.Do I still need to drink eight glasses of water per day?.Do long-time couples start to look like each other as they age?.Polarized lenses decrease overall spectrum reduction by limiting light to a given polarization Sunglasses typically protect from UVA and UVB radiation by filtering these almost completely. How much protection does a pair of sunglasses typically offer? What should you look for when buying sunglasses, if you're concerned about UV rays?
Long-term UV exposure has been shown to promote cataract formation. The infrared waves, or heat waves, cause thermal damage to the retina acutely. What kind of damage can the sun's rays do to our eyes? If you look directly at the sun you experience pain.
We do, instinctively, start to close our eyelids when our eyes even get close to looking at sunlight - what's going on in the body that makes that happen so reflexively? The more exposure, the longer the exposure, the more potential damage there can be.

If you were forced to look at the sun, your eye acts like a magnifying glass and would focus the sun on your retina, creating a burn in the center of your vision . It causes free radicals to develop and they then injure the tissues. The meat of the question: Can you really go blind by looking directly at the sun? If so, how long would you have to be looking?
