So I'm at the point where the optometrist is suggesting that I get lenses that are in between regular glasses and bifocals. I tried it and oh my goodness no thank you. I got such bad motion sickness that I've had to put myself back in bed for at least an hour for the last two days. I've gone back to my previous pair of glasses and plan to call the optometrist on Monday to see (ha) what we can do to rectify the situation.
