These are retro-style reading glasses with clear lenses coated to filter blue light. The coating blocks over 99% of blue light near 400–410nm and about 36% in the 450–470nm range, while letting blue color through in online color tests and giving 100% UV protection with little color distortion. The frame is built for a comfortable, durable fit, with 52mm lenses and a 138mm frame width. They suit people who read or work on screens for long stretches and want mild blue light filtering without a strong tint.
