Now on the Axis I'm not sure the numbers are correct. The lady's hand writing is as bad as my own. I will confirm once I go pick up my remade pair. The first prescription they gave the Axis numbers were 009/005 so the big change on the left eye actually looks like 175 but I think it's actually 115 but the ink smeared to make it look like a 7.
I was told for computer/immediate pair it would be put as half the strength which is close to my old pair's strength. For near? I have no clue. I tried what google said to do but came up with a negative number. Math is not my strong suit. So no clue what my reading glasses would be.  |
175 is a lot closer to 005 than 115. This is because 175 could also be written as -005 (but never is - the cylinder axis is always between 0 and 179).
For near, you'd probably want +2 or +3 to the main number (e.g. -2.75 and -3.00) . +2 would give sharp vision out to 0.5m (about 19 inches). +3 would give sharp vision out to 0.33m (about 13 inches). The numbers for cylinder and axis shouldn't be changed.
It is very important to get the cylinder numbers right. if you got glasses made up with 115 when it should be 175, it would be worse than useless - instead of decreasing your astigmatism, it would increase it.
