Run 'em all day, all night....
Or my personal favorite...
I wear a pair of Smiths. Very comfortable, and really cut down on the glare when on the water.
Anything labeled UV400 will block pretty much all damaging UV rays out.

I dont understand the term too low!If glare from the water is bothering you you may be flying too low.
