The success rate for donating contact lenses to the poor, especially in the developing countries, as you might imagine, is very small. I work with a ton of mission-trip-based applications. It's easy...
I would argue that most prescriptions for younger professionals with an add power are relieving and not replacing accommodation. Those are not SV prescriptions. But according to your definition, they...
I think Peepers used the wrong word. The field of view is the same, but the acceptance of the glasses can go down. For instance, certain reflections may be more noticeable with stronger thinnings.

It is a progressive lens. No question about it. Any lensometer will tell you that. When you ask Essilor for the specifics, they will give you the add powers. So, it's a progressive lens being sold as...
Essilor's slogan is literally: EYEZEN™+ FOR ENHANCED SINGLE VISION
It's "Single Vision" on their system: http://www.eyezenpro.com/images/Eyezen+_Eyefinity_Ordering_Guide.pdf
You don't insert...
Is it true that opticians can legally fulfill a single vision prescription with EyeZen's?
I mean, that looks like a change in the OD's prescription to me.
But, legally, it seems that the...
I am a little rusty on this one but don't Abbe's add each other in some way? If you have chromatic aberration in one lens, a space, and the same chromatic error in another, in the end, you will have...

I may not be the person you want to talk abou this, but here it goes.
Yes. Onliners will Online. And Costco will grab them by their chains (I drop by my Costco optical EVERY damn time I enter the...
While I agree with you, and not only with patients, sometimes I can't tell the difference between them myself, I also understand that people will not see the difference *until the appropriate...
Biases are reinforced by the small set of suppliers opticians and labs tend to work with in a recurring basis.
I like the simplicity of the table, but I am not sure how effective it is given the...
I worked 3 years in retail. Made many mistakes like these. I still do. I know exactly how hard this is. Not everyone can do. Very, very few can do it, effectively, all the time.

> But, if you want your clientele to become frustrated when their lenses chip and crack, please use poly. They will then become your former clientele.
Classic mistake of associating a product with...
Well, PPG created CR-39, Trivex, Transitions and Tribrid. So, among these options their marketing materials tell the whole story:...
My bad. You mentioned jobs, so I assumed it was during my the job execution.
Correct. But my comparison was related to your description of cracks during the lab work. Not after the patient has received it. At the lab, where you can control everything, it should never crack.
Well, it's sensitive because your are cutting, grinding and polishing. Exposing the raw compound. After you apply the protective coatings, it should not crack at all. Like what lensmanmd said: ~0.08%...

Device manufacturers don't control how customers use the equipment. We have our guidelines and our intended use. We love when they provide a good service and don't sell crap glasses. But after they...
Next drk will say that it is not ethical to buy ready-made clothes. Only tailored ones. It's not ethical to buy shoes yourself, you have to be seen by an orthopedist first. You can't eat, you have to...
51.2 million pairs of OTC readers WITHOUT prescriptions are sold EVERY year in the US alone and we don't see any public health problem rising.
