eyes- seeing the sights
We were talking about eyes and vision, and I talked to a few people at CSA about it. I had overheard a conversation where someone said that a gremlin snuck in and made their sights fuzzy.
I had just bought a pair of low-power safety reading glasses as an experiment and let some other people try them. For people that have trouble seeing the sights, especially the front sight, these low-powered reading glasses might be helpful. These are the ones that I had to try out- Elvex RX-500C in 0.5 power. They are available in stronger powers too. You can't find weak reading glasses in normal retail stores, much less safety glasses that you could use for shooting.
For other than shooting, Elvex makes safety glasses that have bifocal lenses made into them. These might be useful for some people for working in their shop.
