OD: right eye
OS: left eye
If you are looking to get distance glasses, ignore the ADD power and input the prescription as is.
If you want reading glasses, add the ADD power to the spherical prescription which in this case will become:
OS: +2.25 , -0.50, x30 (axis at 30 degrees)
If you want progressive or bifocal glasses, type in the complete prescription, don't add anything.
-for progressives, you need to measure the seg height, usually I would suggest using a precise optical measurment tool but for most people, you can do it roughly by using a marker and dotting where the pupil on a set of glasses and measure from the bottom of the frame to the pupil (I usually suggest at least 17mm for maximum comfort)
-for bifocal, you also need the seg height but for measurement, you need to measure from the bottom of the frame to the lower eye lid (NOT the pupil)
For all glasses, you probably need to pupil distance (PD), you can roughly measure it by measuring the distance between your two eyes with a ruler or somehow obtain a pupillometer.
Btw, I have not ordered from this company before so I am not sure about the quality so buy at your own risk. Every lens company produce lenses with a slightly different index of refraction so clarity may vary. I usually deal with big brands like Essilor, Zeiss, Nikon etc.
What would I need to include in the script to order for Computer glasses. My monitor is about 24" from where I sit. Somewhere in the middle between reading books and distance.
