I usually shoot outside and I'm sensitive to direct sunlight. I'm always wearing my shades out so the times I have shot a bow without some eye cover were few and far between but it's something to consider as I will probably start shooting indoors a bit more now that I will joining a local archery club. CDN winters aren't very archery friendly.
Oakley shades are well known for shatter resistance and mine cover the eye well. I will have to look for an indoor alternative.
