I gotta comment
I'm a migraine sufferer and as such suffer in bright light and conditions where there is a lot of glare. Despite taking a daily migraine medication, I find one of the best things is to avoid these situations. Now that is impossible. I love my pool, heading up north fishing, riding, kayaking, 4wding, camping...all these things are outside and in bright light conditions.
Over the years I have had many sunglasses in a search for the best ones for me to reduce light/glare. These have included Bolle, Oakley, no-names, chemist's recommended...anything!! I have had my latest set for 3 years - they are Maui Jim's - grey polarised lenses. I find them excellent. I haven't had a light related migraine since I got them.
Now I wear them a lot. Every day - in sun, cloud, rain conditions. If I'm not wearing them, they are with me just in case I need to. I wear them riding, fishing, playing at the beach or in the pool, kayaking, driving, etc. I'm a pretty hard-core sunglasses wearer
The model I have aren't completely wrap around, but they have a coating on the inside of the lense that "absorbs" light so when some gets in the sides, it doesn't bounce off and hit me in the eye. They were as wrap as I could get for MJs.
Anyway, with all the experience I have in this field as a consumer, I have learnt that there is a big difference between cheap sunnies and expensive ones - in the "sport/utility" range. Don't even get me started on those expensive "fashion" glasses that are only designed for low light conditions (but the fashion conscious don't bother to read the UV ratings
).
I will never compromise on the quality of my sunglasses again. If it means spending $200-$500 or whatever every 3 years, I will do it. When I have a migraine, I spend 2 days in bed and that costs me more. Having "lost" 6 days in 2 weeks due to migraine, you certainly think about the cost to you in both $ (sick leave only goes so far), and time. My glasses have paid for themselves over and over.
For those lucky enough to not suffer from any eye or head related issues - you are lucky, and if cheaper glasses work for you then great. I'm limited I'm afraid.
