Hi gaRCield,
Im with you on this one. I have sensitive eyes and blocked tear ducts which cause me problems. Since I took up this hobby a year and a half ago I noticed after a weekend flying my eyes got sore even if they were fine before.
I had anappointment with my eye specialist and told him about the hobby and asked his advice on the best protection for my eyes, he advised me to buy polarized sunglasses.

I then bought a pair of Wiley X Blink Polarized copper sunglasses with the eye gaskets to enclose the eye from the out side elements {wind/sun}.They have helped alot but not totally solved the problem.
I am interested in this topic as I would be concerned about my eyes and have enough problems without causing more.

P.S I would not mind trying the Zurich.

Thanks Damien
