For people like me who are getting older and even for some of you younger people, eyeglasses can be a problem. Here is the link to a previous article I wrote on this subject Be Sure You have Extra Glasses. It lists all the normal solutions, have an extra pair, buy the cheap magnifying eyeglasses that are for sale in the Dollars store, etc.
This morning I was thinking about this problems and I remembered that when my granddaughter played soccer, she was always breaking glasses. Her parents solved this problem by buying her a pair of sports glasses. She never was able to break them. She used them for several years and they got them inexpensively from a local optometrist.
So I did a bit of research on the internet and found that there are many places selling sports glasses for all different types of activities. For simple prescriptions, these are available at surprisingly reasonable prices.
I also found prescription ballistic safety glasses that are designed to provide impact protection beyond that of typical industrial safety glasses. They are designed for members of the Armed Forces and Law Enforcement that may encounter projectiles that travel at speeds far greater than your typical industrial debris
The United States Military has implemented a series of tests that ballistic safety glasses, sunglasses and goggles worn by the military have to pass. These tests subject eyewear to projectile impacts over four times the velocity (650 fps +/- 10 fps) of normal ANSI testing standards (150 fps). Ballistic safety glasses, ballistic sunglasses and ballistic goggles sold to the military should meet the requirements of ANSI Z87.1-2010 for high impact, and also meet or exceed one or more of the following ballistic standards: MIL-PRF-31013, MIL-V-43511C, and CE EN166B. If you buy a pair check to make sure they meet these standards.
I have not recommended a company because I have had no personal dealings with any of them. My suggestion is that you research both sports eyeglasses and ballistic safety glasses and see what is available that fits your requirements. You may also talk to your own optometrist for suggestions. If anyone has experience good or bad with any of these companies please share it in the comments section.
Depending on how bad your sight is you may be able to get by relatively inexpensively. If you have poor eyesight this may be your most valuable piece of equipment. Get the best you can afford.
