Hi,
I have the following prescription (glasses)
Right : -4.00/-0.50 x 3
Left : -4.75/-1.50 x 154
after i did the vertex conversion, it become
Right: -4.00/-0.25 x 3
Left : -4.50/-1.25 x 154
The customer request that he wanted without any toric (price issue)
May someone help how to do a calculation so that the contact lens is just plain sphere and no cylinder involve?
Thanks in advance.
