Answer 1

NO LESS than 8 dioptres doesn't make any sense...you have misunderstood something somewhere along the line.

At any rate...your prescription, although not written right ( decimals are in the wrong places ), is definately a long ways from 8 dioptres of anything....and they can't be added together to make it so either.

Your left eye has to be .75...NOT 7.5...that doesn't exist.

8 dioptres would be very bad vision...much much worse than what you have.

Answer 2

Do you mean you must have less than 8 Diopters? I'm not sure what you mean by "how" either.
