Honestly, unless you put those cards right in front of your face and study them real hard for too long, nobodies going to see anything. The cards are way down on the table, and your head should be not even close to the table.
But if your really worried about it, you could always test it on someone else, say your gf. Just sit at a table with her, have her wear your glasses, deal her some cards. If you can catch her cards in the reflection, figure out a way that will work.
If I got glasses I will wear them at a table. But usually I dont. So I try to use my eyes for manipulation, and forcing pressure. Its wierd but sometimes staring down a person who just made a big bet, and them seeing you seeing them can be a usefull tool.
