My doctor has prescribed me differential glasses.
Distance: Sph: -6 and Cyl: -0.50
Near: Sph: -4.75 and Cyl: -0.50
Distance: Sph: -5 and Cyl: -0.75
Near: Sph -3.75 and Cyl: -0.75
Is this correct?
Jake says “Drop the astigmatism if it’s just 0.50 diopters, and instead of subtracting 1.5 diopters total, subtract only 1.25. If it’s a 0.25 astigmatism, just drop it, no other changes.”
I’m clueless about astigmatism, cylinder. If the doctor’s prescription is incorrect, please advise me on the correct one.
