OD stands for "oculus dexter" which is Latin for "right eye". OS stands for "oculus sinister" which is Latin for "left eye."
Sphere (SPH) aka Power (PWR)
If you’re nearsighted you’ll have a minus (-) before the number, and if you’re farsighted you’ll have a plus (+) sign.
Cylinder (CYL)
This is only for people with astigmatism. A nearsighted astigmatism will have a minus (-) before the number, and a farsighted astigmatism will have a plus (+) sign.
Axis
This is only for people with astigmatism. The axis is a number between 0 and 180 and determines the orientation of the Cylinder (CYL).
We need your Pupillary Distance (PD) to ensure that your glasses are customized to fit you perfectly. PD is the distance between the centers of each eye. Once we get your PD we can finish your glasses!
Kid PD Range: 35-65 mm.
Adult PD Range: 50-80 mm.
If your PD has 2 numbers, it is typically written 22/20 on your prescription. The first number is the right eye (OD), and the second is the left eye (OS).
1) ONLINE PD TOOL: Virtually measure your PD using our online tool! Click the "Measure My PD" button and follow the on screen instructions. Then enter your PD number in the form.
2) EMAIL A PHOTO: If your little squirmy wormy can't sit still long enough for the online tool (we totally get it!), you can just take a picture at home and we'll measure the PD for you. Follow these directions here.
Sometimes it can be hard with little ones, we totally get it! Take a picture following these directions and we'll measure the PD for you:

"Ludicrous Speed, Go!!!" - Rick Moranis, Spaceballs
Our youth size sports wrap sunglasses fit ages 5-15 years old (depending on head size).
They are silly looking at first but they turned out to look perfect on my husband and are perfect for what he’s been looking for. He does not like having his peripheral vision blocked by regular sunglasses, so these are great for the full view.
I got these for my nephew who plays baseball all year round. He was so excited!
BOUGHT THESE FOR MY GRANDAUGHTERS TO PLAY SOFTBALL AND FLAG FOOTBALL. THE ARE AWESOME! THEY NOT ONLY FIT UNDER THE FACE MASK FOR SOFTBALL BUT STAY ON DURING FLAG FOOTBALL! VERY PLEASED
My daughter loves these. She wanted something to match her dad's fishing glasses, super excited to find these.
My daughter (11) absolutely loves the look and feel of her Roshambo glasses. She uses them primarily when playing her fav sport, competitive softball

How do I know what size glasses I have?
If you have another pair of glasses that fit you well, you can look on the inside of the arms of your glasses for the measurement. You'll see a few numbers separated by squares or dashes, for example 41-16-100. Then you can pick your perfect Roshambo frame to fit!
