Stop wearing them, and take them back tomorrow. Sometimes problems happen with them. I used to have 2 stigmatisms and sometimes it was a matter of being tweaked the wrong way. That's all it takes to have them make you feel that way. The BEST pair (and I work glass for almost 50 yrs) I got at Walmart!!! But there is definately something wrong with them. And I don't buy the "they'll take a while for you to adjust" comments either. I had a specialist that told me that that isn't true and to NOT accept them when you're in the office if they're off. You'll sometimes notice a SLIGHT difference....but should NEVER make you nauseous or dizzy!
