VisionAid H. L. Bouton Slip-on Clear Flexible Side Shields for Safety Glasses -1 Pair

Good product. It is very useful to use for shield in power glass.Without safety glass some company's not allowed there we need to use safety glass over power glass.Here this shied is enough. No need to use another safety glass.

It may fit to most of the frames and looks just ok. If you are looking for a permanent use better to make one prescription safety glasses or look for other options...

these are a great addition to glasses with protective lenses. these protect the sides of the eye, where regular glasses do not.this is my second order and we have used these H.L. Bouton slide-on sidesheilds from the seller VisionAid since november 2016. the person who wears them works in a blacksmith shop and their main function is to run the grinder wheel most of the day sharpening tools. he wears a face shield, but we had 2 scares where he got metal in his eye. then we found THESE. no issues since. he takes them off and puts them on every day, and we ordered 3 pair last time. he just wore through his last pair and we had to order more. theoretically, if you left them on your work glasses, they could stay fine forever. but he removes his daily. eventually the little holder piece wears out. its also important to note that he is not gentle on ANYTHING. so that also is a factor.TL:DRgreat product. 2nd order. after 3rd pair of original order from 11/2016 wore out.

They fit over my glasses which are Versace plastic glasses with thick sides. They fit on great... I can use these at work instead of having to wear safety glasses over my regular glasses. I can't wear contacts at work.cant beat the price.

Great for anyone who wears prescription glasses avoids having to wear goggles over glasses which can put unnecessary weight on bridge of nose

Easy to put on and take off, lightweight, and quick to get used to.

Great for work. Would buy again.
