The 415-KSP Pinhole Glasses combine sporty, modern design with a highly effective square grid insert.
The black plastic frame not only offers a stylish look but also provides optimal side protection for a focused visual experience.
The square grid, with uniformly arranged openings, directs incoming light precisely, helping to naturally focus the eyes. Many users report a noticeable reduction in visual fatigue - especially those with prescriptions under ±3.0 diopters and non-glasses wearers successfully use this grid type for prevention.
