Good afternoon!

I have a customer who has been receiving conflicting information on what type of lenses would be best for his prescription. Hes not the best-off financially, and trying to make the most of what he can afford, but his prescription is strong which doesn't allow for certain options.

SPH OD: -17.50 OS: -16.00CYL OD: + 4.00 OS: + 2.50
Axis: OD: 100 OS: 85
ADD: +1.50

If you have any suggestions I'd love to hear them because I'm torn between extremely thick to keep costs down, or thinner, but risking quality due to price restrictions.

Thanks!
