Despite the beauty of Spring flowers, Oregon Covid cases are again increasing, so I'm back to online shopping only. I get my second dose of Pfizer on Saturday. The weather prediction is for sunshine all week ... a low last night of 32 and the high going to low 80's by the end of the week. Hopefully I will be motivated into walking!
I've been using Zenni to get new glasses and decided I'd like to try prescription readers rather than the one strength fits all. My face is aimed at my computer most of the day. I could NOT figure out how to get reading glasses without buying a regular pair ... with the same frames! I need reading glasses, driving glasses and computer glasses to be easily identified
After investing too much time, I used the little help chat. Here's what he told me:
Reading Glasses
In order to get reading glasses, take the ADD number and add it to the SPH number. Enter the new total in the SPH and do this for both eyes. Remember that the CYL and AXIS don't change so enter them exactly as they are written. And reduce the PD by 3mm. If you have dual PD, reduce 1.5mm by each eye.
Computer Glasses
In order to get single vision computer glasses, take the ADD number and divide it in half. Then add the 1/2 ADD to the SPH number. Enter the new total in the SPH and do this for both eyes. Remember that the CYL and AXIS don't change so enter them exactly as they are written.
???????? I must be getting OLD.
I got my PD measurements from Costco where I used to buy my specs in person. Covid that "in person" right out of my choices. Zenni suggests you measure yourself in the mirror, pupil to bridge of nose or have someone measure you .... but would that be as exact as a professional with the right equipment? I think not. After several tries to Costco, I finally got a sympathetic ear who looked up my prescription to get the measurement.
Can you imagine when Zenni gave me these two formulas??? First I had to learn which was left and which was right on the prescription ... they are Latin abbreviations: OS (oculus sinister) means the left eye and OD (oculus dextrus) means the right eye. (Note to self ... use the left eye to give someone the stink eye!)
I did the calculations but didn't trust myself, so did them again. And then once again. And finally ordered a pair. Let's hope I got it right. I did take the time to email Zenni to put give the calculation to us (like they do IF you order two pair). Wouldn't cost them a thing and would be great customer service. Stay tuned.
Silver frames .... I'm tired of my glasses being the main focus of my face on Zoom!
