A total solar eclipse is set to occur on Monday, providing parts of the United States with a rare view of “totality.” States within the viewing area include parts of Texas, Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine, as well as smaller parts of Michigan and Tennessee. This type of eclipse occurs when the moon blocks the sun’s face, resulting in a momentary darkness. Safety precautions are necessary when viewing an eclipse, particularly in terms of eye protection, to prevent solar retinopathy, a type of retinal damage caused by exposure to ultraviolet radiation. Proper eye protection, like eclipse glasses, is essential to avoid damage to the macular tissue in the retina and ensure safe viewing.
To witness a total solar eclipse, it is important to obtain proper eclipse glasses that meet safety standards. Sunglasses are not sufficient, as they are not dark enough to protect the eyes during an eclipse. The American Optometric Association and the American Academy of Ophthalmology recommend looking for glasses approved by the American Astronomical Society, which meet the ISO 12312-2 standard. Counterfeit glasses may claim to meet safety standards, so it is best to refer to the AAS’ list of approved suppliers. Several manufacturers, such as Soluna, Helioclipse, and Eclipseglasses.com, offer eclipse glasses that can be shipped quickly in time for the eclipse.
It is crucial to check the authenticity of eclipse glasses before using them to view the solar eclipse. Putting them on and verifying that no light passes through, except for sunlight reflected in a mirror, ensures that the glasses are safe for use. Solar retinopathy, a condition that causes damage to the retina due to sun exposure, can occur when proper eye protection is not worn during an eclipse. Symptoms of solar retinopathy include blurry vision, blind spots, and distorted color vision. While some patients may recover normal vision acuity within a few months, others may experience long-term effects. Children should be closely monitored when viewing the eclipse with glasses to prevent eye damage.
Even during the brief period of totality when it may be safe to view the eclipse without glasses, it is important to wear eye protection during other phases of the event. Solar retinopathy can occur from exposure to the sun, resulting in damage to the delicate retinal tissue. While recovery from the condition may vary, prevention is key as there is no specific treatment for solar retinopathy. Individuals of all ages are at risk of eye damage from solar retinopathy, and there is no safe duration of sun exposure that guarantees immunity from the condition. Parents should take extra precautions to ensure that children wear proper eye protection or opt for safer viewing options indoors.
As the last total solar eclipse for the next 20 years approaches, it is essential to prioritize eye safety when viewing the event. Obtaining genuine eclipse glasses from approved suppliers is crucial to prevent retinal damage and ensure a safe viewing experience. By following the guidelines set by the American Astronomical Society and conducting tests to confirm the authenticity of the glasses, individuals can protect their eyes from the harmful effects of solar retinopathy. It is important to educate oneself and others about the risks associated with viewing solar eclipses without adequate eye protection, emphasizing the importance of safety during celestial events.
