MELASA2/4 Pairs Eye Glasses Side Shields, Flexible Slip on Side Shields for Prescription Glasses Fits Small to Medium Eyeglasses

Works well

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.

I was hoping these would add somw light protection as a chronic migraine haver. But these covers just dont have the coverage to be useful. It wiild be like haveing curtains that dont fit yiur window. Better than nothing but shoudlnt be settled for. Unfortunately a return. The shade was not very dark either. Tried to diuble up for sxtra shade but its too tight to get it on the frame if you double up.

Excelente

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.

Those job

I gave this side shield product two stars because your (sun)glasses lenses really need to be vertical or there is a gap between the shields and the (sun)glasses that renders them basically ineffective. Also, while testing them while running the weight of the shields made my sunglasses slide down my nose frequently to the point of being annoying. I wouldn't buy them again.

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.
