Rome,
Thanks for your suggestion. My prescription is also 150. I have some of those vinyl stick-on bifocals you buy at the drugstore mounted on my sunglasses and they work very well for me while driving say if I need to read something in the car. I tried them on my shooting glasses with a similar result as you had. I would raise and lower my head looking at the sights, then target etc.. I usually just got a blurry sight picture. Of course, without the reading glasses I see two front dots on my pistols.
The safety glasses sound like a good idea. I will look into getting a pair.
