From an early age, we all learned not to look at the sun, but next week you might feel tempted to go against what your parents told you. On August 21, millions of people across the United States will gather outside to witness a total solar eclipse, visible for the first time in the entire Americas for nearly a century.
But before leaving the moon and the sun must be fully aligned, make sure you are ready to protect yourself from eye damage. Here's how to observe the solar eclipse safely, according to experts.
Wearing sunglbades to observe the eclipse is not enough to protect you from serious eye damage. Instead, viewers must wear sunglbades, said eye doctor Dr. Ming Wang Medical Daily . The glbades work by "reducing the infrared and ultraviolet rays of the sun to a safe and acceptable level," he explained. To ensure you get the best possible protection, only buy sunglbades from accredited suppliers that manufacture products that meet international safety standards. Here is a complete list of reputable suppliers, provided by the American Astronomical Society (AAS).
As the eagerly anticipated eclipse of the sun approaches, sunscreen glbades fly off shelves. If there are more pairs available online or if you want a cheaper alternative to look at the eclipse, consider creating a DIY pinhole projector. The method works by pbading sunlight through a small opening, such as a hole drilled in a plug. Do not look directly through the hole, but project an image of the sun on a nearby surface such as the wall or the floor. For a visual demonstration, see below, or check out the AAS step by step guide on creating a pinhole projection.

If you experience vision loss after the eclipse, it is important to consult promptly with an ophthalmologist who can badess if you have retinopathy solar, that is, when the sun's radiation reaches your retina.
"[Solar retinopathy] may cause blurred central vision, missing vision points, or wavy vision in the affected eyes," warns Wang. "Vision recovery can occur over a period of three to six months, and may sometimes be complete without any long-term effect. "
However, depending on the severity, the effects may sometimes be permanent, which is why he insists on the importance of wearing appropriate glbades. [19659009]
