I have seen some nice offerings in glass and wondered why my store does not sell any! We are supposed to offer the clients what they want but we neglect that choice; time to see who offers still and why it is a success.

We do glass lenses upon request (which is rare). While we don't promote glass lenses, we certainly won't deny them either. I personally am not a fan for a few reasons. Weight is one and flaking is another. Also, we do a lot of drill and groove mounts (which we will refuse to do in a glass lens)
We do quite a few! In our small town we have a large Amish population. They love glass photo gray and we love that they are private pay! In 15 years I have only had 2 break...both were dropped from significant heights.
Whenever any new product is introduced to a marketplace you must show the consumer how it is "new" and "improved" and "state of the art" or else they wont buy it. But first you must convince the retailers who will sell the product why it is in their economic interest to switch from the "old" product that they have been successfully using for generations.
In the late sixties when plastic lenses were first introduced in the US the big marketing push was their lighter weight and impact resistance. This "lighter" and "safer" mantra was incessantly hammered into the heads of the optician until today the word "glass" conjures up images of little blind children running around bumping into walls and savage lawyers beating you over the head with lawsuits. Of course, the issue of the reduced optical characteristics and decreased abrasion resistance was not mentioned.
I too wonder why it is so difficult to get a pair of glass lenses today. A glass lens sure makes sense in a pair of half eyes or reading glasses. While wearing a pair of glasses that don't "weigh a ton" (an oft used phrase) most folks are not troubled by the weight of their eyewear and the improved visual acuity and durability might be a welcomed feature to their new glasses.
Each lens material that is available to us today has its own unique characteristics and when the proper lens is used we usually end up with a happy customer. It is , therefore, incumbent on the eye care professional to learn the physical characteristics of ophthalmic lenses and avoid "marketing" jargon and "advertising."
As an aside, this phenomenon was accompanied by the elimination of frame sizes. Remember when you could get a given frame with a 16, 18, 20, 22 or 24 bridge?
We do upon patient request. Glass labs, however, are getting harder and harder to find.

That is part of the major issue; when LenSync becomes available we will offer a complete glass offering while showing the weight difference. I have not sold a glass lens in 10 years and probably should put it on my website and see if there are any requests or inquiries.

Used to be, back in the day, we told the supply chain what we wanted and the provided it. Today, the supply chain tells us what they will supply and we are expected to sell it.
It's supply and demand bass ackwards !
Glass lenses can not be made in stock lenses or semi finished blanks by pouring the monomer into a mold and heating them up for while and they are done.
They have to be surfaced all the way and will become a luxury item..
However they are hard to scratch and will not go dull with normal use and cleaning. So far I have not seen any glass lenses advertised and sold by our online optical's at el cheapo prices.
In the seventies plastic was more expensive than glass..............today it can be the other way around.
Why not go for a deja vue higher class luxury.
We sell glass lenses on occasion here, usually by patient request.

An often overlooked product is Thin & Dark glass PGX, surfaced to about 1.5mm, for a weight reduction of 25% to 30% for the lower powers, and a thickness reduction of .5mm to .7mm, compared to standard PGX. Available in SV, ST 28 and ST 7x28, gray only. PGX is activated somewhat by visible light hence some darkening behind windshields.

We offer glass lenses to those that request it. I have seen some beautiful glass lenses that are made using high-index. I am not well versed on the availability of high index glass and as a result feel unconfident using it. Can someone enlighten me?
I have no problem selling glass lenses as long as the patient really wants them. I would like to see through a pair of my own one day, but they are so durn heavy I don't think I'd enjoy it.
We do. It's rare when someone asks for it though.
It's funny how we don't use glass for rx's, but the very best sunglasses are all glass.
As Ralph Drew said...real glasses are made of glass.
