Protect your eyes from harmful blue light with blue light blocking glasses. Designed to reduce eye strain and improve focus during long hours of screen use, these glasses are perfect for working on computers, using smartphones, or watching TV. Features: The deep red tinted lenses help your eyes focus more easily and promote relaxation, reducing eye fatigue caused by prolonged screen exposure. These glasses help filter out harmful blue light emitted from digital screens, such as computers, smartphones, tablets, and LED lights. They can help relieve symptoms like eye strain, headaches, and fatigue caused by extended screen time. The lenses effectively block a broad range of blue light wavelengths (190-590nm), including high-energy visible (HEV) blue light, which is known to disrupt sleep patterns. Wearing these glasses before bedtime helps reduce blue light exposure, supporting the natural production of melatonin and improving sleep quality. The lightweight PC frame in black and transparent color combines durability with modern style, making them suitable for both work and casual wear.
