Looking for advice on selecting some new eye glasses. I've been told of the benefits of digital lenses but don't fully understand what they are, how they work or if two digital lens from different sources are of the same quality.
Hi. I'm Dr. Rick and I have two decades of ophthalmology experience. I'm online and happy to answer your question today.
Are you talking about actual digital glasses, something like these:
or regular lenses that somehow are made using "digital" technology or digital measurements?

I'm referring to the Zeiss Progressive Individual 2 for example.

From this URL

Sometimes, a proprietary measuring device is used for fitting and fabricating a specific brand of free-form, high-definition lenses.

One example is the Zeiss i.Terminal 2, a photo-capture system that automatically measures several fitting parameters — including the distance between the wearer's pupils (PD), fitting height, tilt of the frame (pantoscopic angle) and distance between the back of the lenses and the front of the eyes (back vertex distance) — to optimize the performance of Carl Zeiss Vision's Individual brand of customized high-definition lenses.

So it seems, these lenses involve more measurements of your eye, face, the glasses themselves, and the lens type in order to produce a lens as close to optimal as possible for you as an individual.

But what I don't know is if every vendor goes about the process of evaluating the patient in the same manner or if there are some proprietary products that are better than others.

Thanks for that extra information. I just wanted to make sure that we were both talking about the same thing.
In my opinion, this is an advertising gimmick. The glasses made with these measurements and/or fabrication processes are identical to glasses made the "old fashioned" way.
As far as I am concerned, what they are saying on the website you gave me is just a bunch of BS to sell you glasses. They are no better or no worse than any other glasses.
I recommend you purchase glasses from someone you trust at the best price you can find and ignore this advertising hype.
Does this make sense to you?

I get what you're saying, it's hard to know if it's worth it since I've never experienced the supposed improved vision they tout.

And if you purchase a set of glasses from your regular eye doctor, then purchase a set of these digital glasses and quickly switch back and forth between the two sets, you will not experience the improved vision they tout either....they will be the same in every way that you can tell or an expert can test. Making glasses is not LASIK surgery.....
