Optomologists - What is my pupillary distance?

Hello eye doctors!

I wear contacts, but wear glasses at night, in the mornings, and occasionally for several hours during a day over the weekend. It feels good to let my eyes breathe.

So I went to the eye doc to get my prescription updated and I got them for contacts. Thus, they gave me my powers, cylinder/axis/add figures. They didn't give me a pupillary distance though. I'm looking to buy a cheap pair of glasses from zennioptical.com and need that measurement.

Is this a key measurement or is there a general figure you can give me for me to fill in on the order form?

Thanks,
Matt

You just inspired me to put the end of tape measure below my eye and roll it out. The 5" mark was in focus. I have really bad myopia.

never heard of that one.

I am so nearsighted it sucks. And they tried making one eye see far and the other near and that was a freaking pain in the arse so I opted with seeing far and using reading glasses (dam-it - cute lil red ones that I think are either 1.75 or 2.75 just in order to read). L eye ball is a BC 8.4, -4.0 and the right is -4.75.

but I also have glasses - no not coke bottles but dam close ... when I want to take the contacts out, but I have found over the years that I cannot stand the glasses over a long period of time - even sunglasses or yellow glasses, etc - something about the resting on the bridge of my nose --- regular glasses - I can only wear for a few hours and then I get an annoying headache and I just want to rip them off. grrr.

sorry

Apparently pupillary distance is the distance between your pupils. I suppose I can eyeball it. pun absolutely intended....ba-dum-CHING

ahhhhhh - I guess that would be used for getting a good pair of fitting glasses versus giant eyeball glasses or a set of glasses a 3 yr old would wear.

gotcha!!

My glasses give other people headaches and dizziness. I'm short-sited but have severely mismatched eyes. The left is a mere -1.75 and the right is a -5.2. Luckily my dominant eye is my left one, but without glasses I have no depth perception. With my right eye even my hand on my outstretched arm is just a blur.

Pupils are typically 60-65 mm apart, but as usual, there are those who fall outside of the normal range.

Hold a transparent plastic ruler up to your eyes and take a picture of your eyes from the front. If you can get someone else to take it, that's better and the longest focal length possible should be used. That will allow you to quickly and easily find the distance between your eyes.

Please note that pupillary distance is measured from the center of one pupil to the center of the other pupil.

I suppose you could also get a rough estimate by holding a ruler in front of your eyes, with the end in front of one pupil, and holding a pencil in front of the other eye at about the 2 1/2" mark on the ruler. Focus your eyes on the horizon and slide the pencil slightly left or right until its image seen by one eye seems to be superimposed on the image of the end of the ruler seen by the other eye. Then check exactly where the pencil is on the ruler.

Remember not to poke yourself in the eye!

You mean reading glasses? I always thought that you just tried them on and took whichever matched up your vision best? I have astigmatism, so that never worked for me.

Can they have the glasses made by using visual acuity (the 20/x measurement)?

You can't use a contact prescription for eyeglasses. Different powers entirely. You need your eyeglass prescription, which your eye doctor should have as they typically create it, then lookup some formulas to convert it to contacts.

I found this on a quick google search. http://www.numericalexample.com/content/view/32/33

best bet is to still call your eye doctor.
