<p>OK…so I want to try Zenni. I mean why not. But my prescription seems to be missing some field values (I just ordered a pair of glasses with them from an optician)</p>
<p>I have sph for both eyes. Cyl value is 0.0. My RX says “add” axis 2.75 in both eyes. Zenni has only whole numbers in that field. PD is blank. </p>
<p>Zenni had another field as well…but it’s not even noted on my RX.</p>
<p>These are progressive lenses…both eyes.</p>
<p>Anyone able to help??</p>
<p>I supplied SPH, CYL (one is 0, one -.5), axis & NV-ADD 1.75</p>
<p>PD is easy to measure <a href=“http://www.39dollarglasses.com/help/How-to-order/Pupillary-Distance-(PD)-help/32-How-do-I-measure-my-Pupillary-Distance-(PD).html”>http://www.39dollarglasses.com/help/How-to-order/Pupillary-Distance-(PD)-help/32-How-do-I-measure-my-Pupillary-Distance-(PD).html</a></p>
<p>They have an online chat that is very helpful - try it!</p>
<p>Where does that axis 2.75 go? The axis values on the site are in whole numbers.</p>
<p>I’ll try their live chat!</p>
<p>I’m looking at one of my past orders, so not sure what was calculated and what I actually entered,. My Axis for Right=66, but Left=0. My PD=60. Hope that helps!</p>
<p>I would try the chat. There is more than one way to list certain measurements, so they can help you with that. Once you get the hang of it, it’s pretty simple. I have been very happy with Zenni. I have several pair from them, though not progressive.</p>
<p>This looks to be a good value. I would like to have multiple pairs of driving glasses and at these prices why not? So what do the lenses add to the cost of the frames? It is not clear to me.</p>
<p>My frames where $35, progressive HD lenses $73, Teflon coating, non glare…total about $110. It’s a great price…if you knew for sure it was going to work. BUT I’m not trying a $100 experiment.</p>
<p>So did you order the glasses and were u satisfied?</p>
<p>DH got progressives from Zenni and has been completely satisfied. Just as good as his much more expensive pair ordered from his optometrist. Had to measure his own PD using instructions on the website. All other measurements were on his prescription.</p>
<p>My kids use Zenni every time they get new prescriptions, and have their glasses checked by their ophthalmologists yearly. Absolutely no problems. Yes, you do have to measure your own PD. </p>
<p>When getting an eye exam, ask eye doctor to measure PD and to write it on your prescription. I’d rather use a doctor’s measurement than use my measurement done with yardstick at my kitchen table. Might help avoid headaches from inaccurate DIY PD measurement. </p>
<p>Op,
What are Zennis?
I can help you with your glasses prescription.
You need
sph
cyl
axis
add</p>
<p>The axis applies to the cyl, thus if cyl is 0 (or blank), then axis will be blank.
Add is usually measured in .25 increments. The fact that Zenni takes only whole numbers is very odd and makes alarm bells sound in my head. But maybe it’s how they keep their costs so low (what I’m inferring from this thread).
So if your add is +2.75, and there is no way to enter +2.75 into the website, then just put in an add of +3.00. You may end up holding books a little closer to your face to keep it in focus.</p>
<p>PD measurement is pretty important with progressives. You have more of a margin of error for PD measurement if you are getting bifocals.</p>
<p>"Regular’ lenses don’t add to the cost. I have only single lenses, no progressive, no bifocals. I don’t add any of the coatings that cost extra, except for the dark tinting for sunglasses. I measured my own PD with no ill affect. I have driving glasses for each car and a pair of tinted ones for days when the sun is out. I have 5 pair total right now but have bought many others. Progessives DO cost more but the quality has been good enough so far that even if it cost me $100 it would still be loads cheaper than my insurance would pay for my funky prescription.</p>
<p>I got satellite radio in my car and for the first time needed bifocal sunglasses (so I can see what’s playing.) I went to Zenni and ordered polarized sunglasses with progressive lenses. I put in 2 as the add and zeros for everything else. I picked out a $12.95 frame and the lenses were $57 (either because of the progressive or the polarization or both–if I had just gotten tinting without the polarization it would have been $4.95 I think.) I measured my PD in the mirror with their printable scale. They arrived in about a week and they are fantastic. </p>
<p>Toyo, the “add” is 2.75 on my RX . It’s the axis on zenni that is wholenumbers. </p>
<p>Cyl is blank.</p>
<p>But where would I put the “add” value of 2.75? That is the question!</p>
<p>Enter the 2.75 in the box labeled NV-ADD. NV=near vision.</p>
<p>Op,
Ok that makes sense. Axis is in whole numbers. Follow what wellspring wrote for your add (near vision).</p>
<p>So 0.0 in the axis box, and 0.0 in the CYL box…and then 2.75 in the NV box? </p>
<p>Thank you.</p>
<p>Yes. Or u can leave cyl and axis blank</p>
<p>Thank you! Now I just have to decide if I need two pairs if glasses…for an additional $110! But at least I know how to fill it out!</p>
