I have been wearing Maui Jim's since 1994 when I was a lifeguard on the beach. I have very light blue eyes which are sensitive to light. These glasses have seven layers of composite lenses. They are polarized from the inside and outside. This was especially effective for when the sun was over my right shoulder in the afternoon. With my other glasses it reflected to my eye from the inside and caused me to squint and become sleepy. Also they have earpieces high enough to not block peripheral vision, so they are especially good for driving as well.
Lastly, they have a lens replacement policy.
My original pair flew off a table in a storm which scratched the lenses, I sent them back, paid for shipping ($69.00) and they were replaced for free.
My new pair have prescription lenses for distance and are a blessing when driving during the day.
The polarized lenses significantly cut down on glare which makes them very useful for people with light-colored eyes.
