Let's Be Frank About on-line ordering
So you thought about ordering on line. It’s sure cheaper... and that’s what it is, cheaper. How is it cheaper, not less expensive, but cheaper.
That’s simple. The services are reduced. In reality they are non-extant.
That’s simple. The services are reduced. In reality they are non-extant.
In our office you are paying for the service, not the materials so much. As an example, single vision plastic lenses in our office cost $70.00. The laboratory cost for those lenses when they buy in bulk is $1.00. It is the services the lab and our office do to those $1.00 lenses that you pay. Thus, when the on-line company provides no services they can and do mark their prices down.
We provide 22 services for every pair of glasses. See below for each of those services. The on-line company only supplies one, and that is not done very well.

Wonder if I send the name and measurements of my current frame into the lab?
Most on-line labs use their own frames (they can’t afford to offer quality frames at their prices). Even if you use the measurements of your frame, the same measurements in another frame do not mean that frame will match your face.

But wonder if I send your prescription with the measurement between my eyes into the on-line company?
Yes, you could and is required by law (often ignored by on-line companies). That only covers the first three of 22 points. That’s hardly any service at all. The on-line company has to make the prescription correctly which is highly doubtful. Recently we provided a patient with that measurement, and the on-line company made the glasses wrong causing double vision.

Couldn’t you verify the glasses and customize them to my face?
Yes, you would pay a modest for the service that would last the life of your prescription. Yet:
1. We could not be sure we could bend the frame.
2. We could not be sure the frame would hold it’s adjustment.
3. The frame could break with an appropriate adjustment.
4. The frame may not even correctly fit your face.
5. The above four assume the prescription was made correctly. That is not likely.
If the on-line company made my glasses wrong, couldn’t I tell the difference?
No, you may not be able to tell, especially of the small discrepancies that cause your vision to change and worsen. The big difference you would obviously note and not even attempt to wear the glasses. Besides, we see very few people bring in on-line glasses for verification. Most that were brought in were wrong.

Adjust-ability of the frame.
It needs to be flexible to bend but not too loose so as not to hold its shape. We have sent some nonadjustable frames back to our vendors |

13. Correctness of the written prescription by the time it gets to a lab (Our lab is set to pick unusual trends in the Rx to guard for error, and does not rely on the quality (or lack thereof) of a fax.
14. The quality of the equipment at the laboratory and of the lenses supplied by the lab. Our lab is over a 10 million dollar facility. 15. The training and expertise of the technicians (or lack of) at the laboratory 16. The adherence to standards of manufacturing the glasses at the lab |
17. The verification by the laboratory before sending the glasses out (our lab has over a 95% correct rate).
18. It is not turn around time but quality. Just because it is delivered quickly doesn’t mean it is right. Although our lab delivers in a week and in emergency we can rush in 3 days.
19. Once the lab makes the glasses we verify them to be sure they are made correctly before we deliver them to you.
20. We then customize the glasses to your face for ideal optical use and comfort.
Glasses touch at only three points:
1. on the nose
2. in the mastoid hollow behind the right ear
3. in the mastoid hollow behind the left ear

The temples do not touch the ears. That hurts.
The temples do not touch the side of the head. That makes them slide down your nose.
The glasses need a pantoscopic tilt (tipped so the bottom of the lens is closer to your face than the top) or your field of view is narrower and you can have distortion.
The front of the frame needs to be level on your face. This is especially important in a bifocal.
