Review on Eyekepper Blue Light Shield Computer Reading Glasses: Yellow Tinted Lens Eyeglasses (Tortoise) - Protect Your Eyes from Harmful Light by Demetrio Lowe

These glasses block blue light very well. I use them at night when I'm reading something on my Kindle or smartphone. The only initial issue I had was that they were very smeared when they arrived. It took me a while to clean up the dirt. Rating updated and rating downgraded from 4 to 1 star. The frame holding one of the lenses is cracked. I have a pair from another company that I previously purchased. They are still in excellent condition. I will not buy this brand again.
