## Description

desertcart.com: Swanwick Blue Light Blocking Glasses for Women, Men Anti Eyestrain Headache for Computer, Gaming, TV, Phone Screen. Sleep Aid. Crystal Day Swannies (Regular, Sapphire) : Health & Household

Review: NOT lightweight; smudges easily - I really like this blue color. The plastic lenses are of high quality, and the vision is not distorted. My almost-daily headaches and dry eyes have been so much better since using these. HOWEVER, they smudge very, very easily. The included "microfiber" cloth doesn't clean it well. It's strange, Swannies being mid-tier glasses (around $80). I also bought the Night Swannies, and I'm satisfied, but they also have the same issue. For the price tag, I was expecting them to be more comfortable. They are NOT lightweight, in my opinion, so this is a big con. 2-Month Update: It's been a while, but I am not satisfied because they are still too tight on me. Ended up returning them and buying another (cheaper, but amazing quality) brand, at a discount. The new ones are lightweight and comfortable.
Review: Thumbs up! - Glasses deliver promised benefits when worn consistently. Also love the look!
