Don’t Endanger Your Eyes During Monday’s Eclipse

With the coming of the eclipse on August 21, our office in La Grange has received many calls regarding “can I use X, Y, or Z to protect my eyes during the eclipse?” Unless the caller is talking about approved “solar glasses” the answer is almost always an emphatic “No!” Let me explain why, with information on both sunlight and eye anatomy. If you just want to know what sort of glasses you need, and trust me when I say intense sunlight is bad for your eyes, feel free to skip to part two of my letter.

The sun is 92 million miles away. Despite this, it manages to illuminate an entire planet. That’s pretty strong. I know it seems obvious, but how many light sources do you know that can be seen, in the daylight, even a mile away? And that’s just visible light. Fifty percent of what comes off the sun (solar radiation) is visible light. A small percentage is UV light, enough to give us sunburns, or even corneal burns, much like welders can get, if there is enough reflection from snow or water.
