Mate as has been said don't worry about it. Get your glasses and if you can soft contacts. All will be good.
Nomorecatring, if you are -.075 in each eye that is not too bad at all. Before laser surgery I was -5.75 in the left and -6.25 in the right.
Now I have perfect vision, well actually better than perfect. In the left eye I am now 9/6 and in the right 6/6. I have had this since 2003. I would recommend it to anyone. At 16 though wwejosh, you are too young for laser surgery, you need to have stopped growing and your eyes to be stable for at least 12 months. All the best.
