The best of PlanetGlasses Corrected Visual Acuity Cva Glass Pinhole Microhole Hole Men's Sunglasses (TBOP 0S2, Black)

Useful

A good product at reasonable price

Good to use but Center of Curvature is not defined so is the axle.

Finishing of holes, not good. Not serving the purpose

this product is based on the concept of pinhole (from our school days). i brought this as a screening device for refractive errors in my patients (i'm a general practitioner). But this device does exactly the opposite of what is mentioned in the product description. You can't see anything after you wear it. The return policy is also very irritating and so ppl will generally not bother. I urge ppl not to buy this product ....its fake.One person found this helpful

Glasses are good...frame has a nice shape but it is not strong, we have to use them carefully!
