Glare is a distracting and sometimes dangerous excess of bright light and can happen day or night. Glare can cause squinting, eye fatigue, and in extreme cases, even temporary blindness.
Did you know…
In daylight, glare can occur when walking indoors to outdoors, moving from shade to sunlight, even from reflected light off of surfaces like cars or sidewalks
At night, glare can occur from oncoming headlights while driving, or from bright reflections off of wet roads, even signs
Glare can impair visual comfort and visual quality, which can diminish healthy sight
Anti-reflective (AR) treatments are available for many lens products to help protect your eyes. AR treatments are proven to significantly reduce glare while increasing visual comfort. Best of all? These types of lens treatments and materials, plus others like photochromics and polarized lenses, can often be bundled into one lens product for maximum versatility, as well as eye protection.
Quality sunglasses are also very important for reducing eyestrain, headaches, and fatigue. The opening at the front of the eye, called the pupil, controls the amount of light that enters your eye. In conditions in which a great deal of light is present, such as when you walk outside on a very sunny day, the pupil may be unable to constrict enough to keep light to a comfortable level, causing you to squint in order to further limit the amount of incoming light. Muscle fatigue associated with constant squinting and the continued construction of the pupil can cause headaches, fatigue, and eyestrain.
Tip: When you step outside, you should wear sunglasses to protect your eyes from glare.
Sunglasses are an absolute must for proper eye health. This is also true if you've just had any kind of surgery or are taking medicine that makes your eyes extra sensitive to light.
