2/4 Pairs Eye Glasses Side Shields, Flexible Slip on Side Shields for Prescription Glasses Fits Small to Medium Eyeglasses

They're flexible but stiff, so they will stay on your glass earpieces solidly. I like that they're smoked translucent so I don't get glare from my peripheral vision, but they also work well to provide side safety that doesn't fog up my existing prescription glasses like wearing an oversize pair of safety glasses or goggles would do. If you want to add some side protection to existing glasses, this is the way to go.

I love that these can fit my sunglasses that I use when I work out. Wish they worked on my everyday sunglasses. Besides that I would highly recommend these for metal or thinner side arms. Excellent sun blockage.

They came with smears and markings all on them. Not at all impressed. Wasn’t Ted all this damn time just to have to send back. Very Disappointed !!!

When I drive during the daylight hours, I usually wear sunglasses. Many times, the sun hits me from the side causing a distracting glare. These helo reduce that glare and make my driving safer and more enjoyable. I highly recommend these for anyone who needs to reduce the sun's glare.

With quite extreme rays of the sun angled into the plastic, it can the light to somewhat glow uncomfortably in your peripheral vision. So full-on sun is still too much glow for my eyes in the worst conditions.

I bought two pairs of the tinted shields for my wife and I to use during our assent of Mt Kilimanjaro. These helped shield my eyes from crosswind, sunlight, and glare from the sides. Worth the very inexpensive cost to add these onto our prescription sunglasses. The photo is showing Mt Meru in the background while we're above the cloudlayer.

Well, look for yourself. Does it look cool?

Arrived on time and as ordered. I Used them to convert old prescription glasses to light safety glasses to work in the shop and yard. The shields were easy to put on and fit well enough for my purposes. You still look kind of dorky with them on but for me that wasn't the point. I haven't tried taking them off but should be easy. I also thought I could use a hair dryer to get them to fit tighter against the top of the frame around the lenses but decided they fit close enough. In all, a perfect off the shelf product for me.

Yo los compré para evitar que se filtre la luz por un costado del lente y me funcionarion bien, se colocan fácil y se quitan fácil, no son molestos y cumplen su función.
