Q: I'm trying to order +2.50 readers but having trouble figuring out how to do this on your site. Can you please assist?
Thank you, Clair
A: Dear Clair Berry, We would like to tell you that you can choose single vision reading lenses and fill the strength+2.50 in the SPH value.
We would like to tell you that if you don\'t know the PD,
you have rights to contact your doctor/optometrist to get your accurate PD value, or you can download this APP to measure it: https://www.glassifyme.com/pd-meter-app/ .
