Review on ✈️ Enhancing Aviation Safety: ASA-OVC View Limiting Device for Clearer Vision in Overcast Conditions by Jared Allred

They fit me very well. I like being able to flip them quickly on the DA and not having to fiddle with Francis' hood. Expect to have to buy a hard case to store them so they don't get damaged. You can't throw them in your flight bag. They also work great with my rounded sunglasses, but with my regular glasses I have to wear a baseball cap for the visor to block the light from above. My glasses have 53 x 33mm lenses with a 20mm bridge (size 53-20). This is perfect for a 20mm bridge.
