Since I work from home now, I’m online most of the day, so I need glasses like these to block out the UV and blue light from my monitor. You can see a slight change of color when you put them on, but not much. It’s likely they’re doing their job and are comfortable to wear most of the time. Overall, a very good product.I'll be returning these to Amazon. The glasses are listed as "computer glasses" in the product information, but they're just reading glasses. It even says "reading glasses" on the box. If all you need is some simple full lens reading glasses, these are fine. But if you're really looking for "computer glasses"... keep searching. Misleading product information.Glasses arrived in a sturdy box! The frame has just the right flexibility to fit my slightly large head. The frame is comfortable on my ears and nose. The lenses do their job perfectly. I noticed the first late night that I was on my phone, my eyes didn’t feel stressed or tired anymore.Great glasses for the price. Comfortable.I got this glasses for my husband and he really liked ,he's not getting tired when reading a lot the blue light it's excellent .We highly recommended for seniors like us and we getting more just in case.These look great but are loose fitting. I am afraid they will fall off if I look down.These glasses are flexible comfortable and it's perfect for any screen good value for the money....Excellent product.I have tried quiet a few reading glasses to reduce my PC glare & consequent tired eyes.Tint is just right, not too heavy. They are light weight on the nose. Reasonable hard case supplied.Would rate them as a 8/10 after 6 months of use.
