I want to purchase fastack goggles. I ve chosen one model and it looks cool for me. But i have number in my eyes. I wear specks with number -0.25 R and -0.75 L. I am affraid that if i buy goggles then i will get headach. But i do not get pain if i dnt wear specks for long time. If any of u guys are Eye specialist or optician then Please suggest something.. If i buy it and if i get pain in head after wearing it then it will be a waste right? so guys please help... thank you...
