These are simply the best sunglasses I've found! After cataract surgery, I had great distance vision for the first time in my life, but needed reading glasses for near vision. I homeschool my granddaughter and with spring weather starting to make an appearance she asked me if we could read outside. I told her the sun on white pages was too bright for me. Then I had an inspiration to look for sunglasses with bifocal reading lenses. Yes! Such a thing existed! Amazon had it! These are absolutely perfect. We can now read outside, and I am thrilled. The bifocal part is perfect, the clear sunglass part above is perfect, and the glasses are comfortable.
