Why Opticians Are Concerned About Eclipse Glasses
With a solar eclipse cutting across the nation on August 21st, so-called “solar eclipse sunglasses” are flying off shelves of convenience stores, gas stations, and supermarkets. However, opticians advise against relying on these products to protect your eyesight. It may be tempting to look at the sky when the eclipse occurs, but it’s not worth the risk to your eye health.
Why Is Looking at the Sun So Dangerous?
You may have heard the myth that staring at the sun can cook your eyes, but the reality is just as dangerous. Overabsorption of solar energy causes the eye to overproduce a chemical called all-trans-retinal, which, when exposed to light, begins reacting with oxygen. This reaction releases volatile oxidants into the eye, the biochemical equivalent of lighting a powder keg. Take it from an optician: Looking at the sun is very dangerous.
What’s the Problem With Eclipse Sunglasses?
These glasses consist of a dark plastic film attached to a cardboard frame and typically sell for less than $4, making them an easy way for questionable manufacturers to turn a quick profit. On August 17th, Vanderbilt University recalled 8,000 pairs of eclipse sunglasses they distributed at a recent festival because the original distributor couldn’t be verified. According to opticians, these products do not meet safe-viewing standards. In some cases, the quality assurance markings may be forgeries. Even major vendors like Amazon® are taking steps to make sure their products are safe and contact customers who may have purchased duds.
How Can I Watch the Eclipse Safely?
A pinhole projector is the safest way to watch the moon pass in front of the sun. All you need are two pieces of cardboard and something to make a hole with, like a pin or needle. Poke a hole in one piece of cardboard and place it in the sun’s path. Leave the second piece intact and put it in a shaded area. Make sure the two pieces are aligned properly, so the image is displayed on the second one. You can track the moon’s progress by watching the shadows on the cardboard.
Take advantage of this rare occurrence—but remember, one day’s marvel isn’t worth damaging your eyesight.
