Looking directly at a solar eclipse without proper eye protection can cause "eclipse blindness" or retinal burns, which can damage or even destroy cells in the retina that transmit what you see to the brain. This exposure to the suns rays can cause permanent damage to the eyes, leading to a condition known as solar retinopathy. The light from the sun is so strong that if concentrated on the retina, it can cause burns and destroy cells, leading to temporary or even permanent damage to vision. Therefore, it is crucial to use special-purpose solar filters, such as eclipse glasses, to safely view a solar eclipse. If you or your child experience any changes in vision after viewing a solar eclipse, it is important to seek treatment from an eye care professional.
