Hey, that's me in the picture of the story about how Curran started with the billiard glasses. I'm local to him, and had been going to him (and his father) since I got my first pair of glasses in the 4th grade (I'm 41 now). That picture is my second pair from him, probably around 2013 or so. My first pair of billiard glasses from him was about 2006 or so.
What Curran does is use a frame design that screws to the lenses on holes the optician makes on the lenses himself. And he cuts the lenses to any shape he wants. 99% of the places today don't do anything like this. Its old school, "Guild Certified Opticians". Curran's father started the business in the 1950's or 60's. Now they are on their third generation, as the grandson works there as well. In 2005 or so I had bought a normal pair of glasses from him using those frames that screw to the lenses. It was a new frame design at the time. He was doing some interesting things with the shapes of the lenses (since he cuts them himself), and made me a pair with sort of hexagon shaped lenses. A couple year later, I asked him if he could make me a pair of billiard glasses with the same style frame. I went in there with my pool stick, got in my stance, and we marked where my eye was looking through the lens. He then made a custom lens with the "optical center" of the lens at the place where my eye was looking through when in my stance. Because the frame and nose pads can be mounted anywhere on the lens to the holes he drills on the lens, means the lens can be positioned optimally on your face for your pool stance.
Over the years, he's refined his technique, and now can make pool glasses for a player that is not local. I think he has a way to measure the face of the player and the eyes that he discusses with the player.
If you ever go to Philly for the Expo, he is in the Philly burbs, about 30 min from the various locations the Expo has been held at over the years.
His price is higher than other places, but its a case of you get what you pay for. I moved away from Philly, and have tried a couple other lens-crafter type places for my regular glasses. I hated them all, and they never fit my face right. Now, when I go back to Philly to visit my family, I make it a point to stop in his shop whenever I need a new pair of regular glasses.
Both of my pool glasses are still working great. I only got the second one because he changed the frame slightly that I think looked better than the really old one I bought first in 2006 or so. Before Corona, I kept the old pair in my glove box, and my new pair at home for my home table.
Curran is not a pool nut like we are, so he doesn't know all the ins and outs of the pool world. He posts on here sometimes and people think he is spamming. But he's just an old school optician with a product that is really good. He also doesn't realize how cheap pool players are
I think he has lowered the cost of his glasses a bit over the years to help us cheap pool players
IMO, and I have no business affiliation with Curran, and don't receive any discounts from him. I'll keep getting both my regular and pool glasses from him as long as he is still around.
