Polycarbonate is shatterproof and can withstand almost anything which is why they are used for children under 18 and anyone desiring maximum eye protection. As I last remember glass lenses only come from overseas because of the liability, domestic production ceased year ago.
Well one of the pairs I had a year or so ago I dropped, and the "glass" chipped off the bottom of the lens (half rim glasses). So whatever it is, it is indeed breakable.

We use pupilometers now which give monocular PDs, which are necessary for Progressive Lenses and high prescriptions.

If your prescription is not that high it won't make a huge difference. If your face is not symmetrical (eyes different distances from your nose) it can be an issue. There is also the issue of your current glasses may have been made incorrectly and if your new PD is accurate and your old one wasn't there can be problems. That is why I always checked the previous PD and had no makeovers because I spent a little extra time. If I didn't, the patient may have had incorrectly made glasses and if I made them correctly they wouldn't be able to see as well. They would think I made them wrong and was just making excuses. If the PD was off, I would explain to the patient that their old glasses were made incorrectly and I would be making them correctly and it would take them some time to adjust. Sometimes they were so far off you could only do a partial correction and finish them the next pair.

That happens all the time, that is why we recommended polycarbonate for those types of glasses.

I have had POLYCARBON one time (They accidently made them this) -- Gave me headaches like crazy!!

Im sorry I posted that in this thread Tallysmom,I was speaking GENERALLY about Glasses,perhaps I could have found a better thread...

The headaches are not caused by the lenses being polycarbonate. They're caused by the frame being fitted wrong and/or the lenses being the wrong prescription. Try ordering the same glasses online, from more than one website, and see if they all give you the same headache. In that case, the prescription itself might be wrong. The doctor who gives you the prescription is not guaranteed to never make mistakes.

Costco costs me about two glasses since transitions suck. I have vision insurance through work thankfully but it's still a LOT of money for my two pairs and I don't get glare resistance. It's just the RX and that. And I don't even have bi/tri focals or progressives. The frames I get are in the $60 range, give or take. It's honestly the cost of the lens going in them.

Congrats I guess?

I didnt say people should guess at their PD, im saying its not some special science.

I can't believe all the whining about how expensive a custom, prescription item costs when a person wears them every single day for years. They aren't like a $30 pair of jeans that you wear once a week or once a month, and if they don't fit, they can be returned and resold to someone else. They are prescription; a medical device for your eyes that is designed to correct a problem you have with your vision. (And one that comes with a warranty too).

People often buy phones that cost more than glasses. But glasses serve a more important purpose. If you find nice ones cheaper, great, but don't complain because a specialized medicine you wear daily for years is expensive. It should be.
Business Model | Luxottica Too bad I'm not a shareholder.

Re: expensive phones. The eyeglasses that I purchased 11 years ago cost about $1,000. The eyeglasses I purchased (but returned) this summer retailed for $1200 but cost about $850 after the "discount". The two sets were virtually the same. Similar Silhouette frames, hi-index, progressives, anti-reflective, blah blah blah.

I purchased my first Iphone in 2008. It was a 3g. Last year I purchased an Iphone 6+. Was there a major advance in smart phone technology from 2008 to 2015? Uh huh. I paid for that advanced technology. My glasses? Same glasses, same technology, same cost.

So why has the cost of eyeglasses NOT come down since 2005? Is it because there are fewer customers now than back in 2005? Or is it because the stores have a captive audience? Or?

It is a science to get it right and depending on the prescription it may or may not make a difference. Some people are hypersensitive to a PD and others not so much. It induces prism if its off and some people can tolerate it and others not.

Not everyone wears the same one daily for years. I have a couple of pairs I wear for different occasions. I have a progressive pair that I only wear to look at the computer. I have a transitions pair I wear outside. I have a few single vision pairs I bought online (I didn't get Zenni but went somewhere I could try the frames on and got my PD from an optician). As it is, insurance will only pay for one every 2 years and since I can't wear the progressives outside because I don't feel safe driving in them, it's really nice to have options to buy options outside of the 4-year timeframe.

I think I am going to try Warby Parker for Progressives since they may still be cheaper without insurance than the places my insurance is accepted since those are so limited and often expensive. I have access to a brick and mortar Warby Parker and it's apparently only $295 for a progressive pair.
