Seventy years ago, polarization was developed to reduce glare from reflective surfaces. Polarization did a good job until the arrival of the "Digital Age" . Now, it is difficult, even impossible to read smart phones, GPS units, digital gas pumps, chart plotters, fish finders
and other digital screens, or instruments. Polarization will probably be used less with the advent of more digital electronics, and devices.
"Extreme Glare" lens technology outperforms polarized lenses in most reflected light conditions. They provide a optically clear vision of digital instruments on boats and planes—not to mention car rear-view camera displays, and modern dashboard instrumentation.
Extreme Glare Sunglasses' lenses were originally created to block blinding glare in direct sunlight as well as all reflective surfaces. They provide welcome, and soothing relief, as well as comfort and eye protection.
Migraine headaches, medications, surgery, trauma, illnesses, diseases and a host of other medical conditions often result in eyes that are very sensitive to most light. Those with "photophobic" sensitive eyes will find these sunglasses invaluable as part of their daily wear and will no longer need to suffer in bright light.
