Do not use while driving or walking. It is recommended to take a short break every 30-60 minutes. ╳ These glasses feature a coated blue light blocking lens, which will have a slight yellowish tint. This is because the coating works by counteracting blue light, helping to reduce eye fatigue, aging, and potential retinal damage. ╳ To prevent scratches, avoid wiping the lens surface directly with rough fabrics. Rinse with mild detergent and clean water. ╳ For selecting your presbyopia strength, the chart below is for a simple self-test.
