Clear as it gets

Picked this up to use in a camera rig to take better welding shots for videos. I 3D printed an adapter and couldn't be more happy with the results.

These lenses aren't the greatest I've ever used, but they're ok. For the price and being a pack of 100, who cares? Even IF I have to change them out every few days, the pack will still probably last me a year. They fit as expected. Overall, good value for the money.

I've gone through a few of these lenses already, and they’ve held up well under regular use. They're 0.04" thick, as described, and that extra bit of sturdiness makes a difference when swapping them out frequently. They don’t feel flimsy or overly brittle, and I haven’t had any issues with cracking during installation.Sizing is accurate — they fit snugly into standard 2"x4.25" helmet slots without needing to be trimmed or forced. The clarity is good out of the packaging, and there’s a protective film on both sides that peels off cleanly.So far, quality has been consistent across the pack, and having 100 on hand is convenient for anyone doing a lot of welding. No warping or noticeable visual distortion either. They serve their purpose without any surprises.

This adds another degree of protection to your lenses if you are using the auto-darkening lens. It's worth it to be able to simply put a new screen off after a while and thus you will have good vision again, and still protecting the other lens. Overall, I think this is a great value and makes sense in my book.
