Well now, I don't know about the rest, but the cheapo's that have distortion also give me a headache. In fact, any eye protection that has the least amount of distortion would give me a headache after about 20 minutes. Before I wore glasses I would spend days looking for a pair of SG that did not have distortion.

Now that I wear glasses full time, bi-focals so I can see to read , I went to the wear overs. Have 2 pair, one for fishing and semi-bright in brown and the other for full sun in black. Pick them up in Walgreen's for about $25 and can wear them all day fishing, playing golf, driving, whatever.

If you wear glasses, check out the wear overs.
