Solar viewing glasses are specially designed eyewear that allows people to safely observe the sun. They are made with a special filter that blocks harmful ultraviolet (UV) and infrared radiation, protecting the eyes from damage. These glasses are essential for viewing solar events, such as solar eclipses, without risking eye injury. It is important to use only certified solar viewing glasses that meet the ISO 12312-2 safety standard. Regular sunglasses, no matter how dark, do not provide adequate protection. Always check for proper certification before using them to ensure a safe and enjoyable solar viewing experience.
