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! ## Features - CONTROL BLUE LIGHT EXPOSURE: Crystal Day Swannies come with modern translucent frames and provide the perfect balance of protection against the most harmful spectrum of blue light (400-450nm), while letting in some of the healthy blue light (450-500nm), which helps regular circadian rhythm and improves alertness and memory function. - ELIMINATE SYMPTOMS OF DIGITAL EYE STRAIN: Made to be worn all day, everyday, Crystal Day Swannies can help eliminate symptoms of digital eye strain such as dry, sore eyes, irritation and headaches, whenever using a computer, tablet or phone. - ADJUSTABLE FRAMES: The cellulose acetate frames can be heated up and molded for the perfect custom fit or adjusted if bent out of shape, and the spring hinges provide a wide range of movement for extra comfort and durability. - HIGH QUALITY LENSES: Our high quality, clear CR-39 lenses come with anti-reflective coatings to provide superior visual clarity while protecting your eyes against harmful blue light. - 100% SATISFACTION GUARANTEE: We provide a 100% satisfaction guarantee. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Q648WPC | | Best Sellers Rank | #1,316,464 in Health & Household ( See Top 100 in Health & Household ) #8,291 in Computer Blue Light Blocking Glasses | | Customer Reviews | 4.3 4.3 out of 5 stars (13) | | Date First Available | July 19, 2019 | | Department | unisex-adult | | Is Discontinued By Manufacturer | No | | Item model number | SW205-BLR | | Manufacturer | Swanwick | | Product Dimensions | 3.25 x 3.25 x 8 inches; 0.04 ounces | ## Images ![Swanwick Blue Light Blocking Glasses for Women, Men Anti Eyestrain Headache for Computer, Gaming, TV, Phone Screen.
