Blue light blocking glasses may help when spending long periods of time in front of the computer or on your phone.

Blue light glasses are largely marketed as a solution to eye strain and as a protectant for the retina. Their effectiveness is not backed up by the science, however. While they are successful in blocking blue light, blue light is not necessarily something that needs to be filtered out for ocular health.

Blue light lenses can effectively regulate our sleep-wake cycle and indirectly support mental health. These lenses promote healthier sleep patterns and overall well-being. Blue light lenses may contribute to improved hormone regulation and alertness and provide benefits for managing depression and anxiety.
