Glare from both the sun and reflected light forces your eyes to work harder as they try to interpret information. Your pupils can also chase reflected light which causes the constant expansion and contraction of the eye as it adjusts to the angle and intensity of light.
As a result, you can suffer from eye strain and fatigue with your eyes feeling tired and sore.
Polarized sunglass lenses help reduce eye strain and fatigue by blocking glare and alleviating discomfort. Polarized sunglass lenses are the only lenses that block blinding reflected glare that can severely compromise vision and cause great discomfort and strain.
Therefore, wearing quality polarized sunglasses helps your eyes to feel more rested, relaxed and protected in bright sunlight and around reflected light.
