These are round, matte-finish acetate glasses from Dr. S Eyewear built around blue light filtering. The CR-39 lenses block up to 99% of blue light and absorb UVA, UVB and UVC, with anti-glare and anti-reflection coatings. Spring hinges hold the fit, and a case and cleaning cloth come in the box. They suit people who spend long days on screens and want a classic round shape rather than a sporty blue-light frame. Against typical budget blue-light glasses, the CR-39 lens material and full UV absorption are the main step up; the trade-off is a single round acetate style with no tinted or clear-lens options described.
