I wouldn't be without them, except when driving at night - there is a background loss of about 10% of transmitted light, even when they look clear. I don't know whether there are different quality photochromics, but the ones I buy have a quick response and go surprisingly dark when needed.

Certainly most shooters seem to aim with the right eye.

It's an addition so for reading yours would be R 1.00+1.75 = 2.75 and L
0.75+1.75 = 2.5
Ok, so do I need two pairs of glasses then. One pair with R1 & L.75 for 'looking' and another pair R2.75 & L2.5 for 'reading' (confused) ;-(
All the best ..
