Blue light emitted from the sun is essential to your body. However, exposing your eyes to the artificial blue light from computers, fluorescent lighting, smartphones and other digital devices may cause eye strain and interfere with sleeping. Blocking UV and HEV (high-energy visible) light can help protect against cataract and age-related macular degeneration. Ask your trusted eye care professional about blue light blocking lenses available to you. Our tip: If you are working on your laptop, tablet or smartphone long hours, we recommend giving your eyes frequent breaks by looking into the distance often.
