I need to order a cheap pair of prescription sunglasses, and since they are very cheap on the net I was going to do it from there but I am having trouble working out my prescription.

The information on the prescription is:
BVD: 12mm

Right Eye:
Sphere: - 3.25
Cyl: -0.25
Axis: 90

Left Eye:
Sphere: - 3.25
Cyl: DS
Axis:

The thing that confuses me is the fact that the left eye doesn't have as much info for it as the right, and also it says DS for cyl, does this mean something? Since they haven't written any numerical values for Cyl and Axis does this mean its 0 or the same as the other eye?
 
Erm, dont quote me on this, but I think it means that in your Right Eye you have a slight Stigmatism, wheras in the left eye, you dont
 
exactly what shredgod says ( myopia and a little astigmatysm in the Right eye and only miopya in the Left eye)


I order some time ago two pair of eyeglasses from zennioptical

that BVD value i do not now what means:confused:

in your left eye you put DS in the cyl field and 0 on the axyx field ( you find that fields in the online prescripion)

but ,in order they make your glasses correctly, you need to give them the PD (pupilary distance) value in mm - you could ask a friend to help you to obtain it, by him holding a rule in front of your eyes and reading the value from pupil to pupil:)

most of the people have a PD of 62/63/64 mm

BVD means Back Vertex Distance. It's the measurement from the front of your cornea to the back of the spectacle lens:)

Don't worry about that though, think it only matters in strong prescriptions.
 
Cheers guys, looks like its a no go anyway as I'd need them by friday and most places say 14 days :(
