My doctor asked that I try and get pictures while playing. Wanted to be able to see where my eyes hit my regular glasses while aiming.
I played a bit on my home table and determined the shots when I’m usually down the lowest. I finalized that to 2 positions.
Then, I got the camera, tripod and remote out. It took a while of trial and error, looking at test shots on the large monitor on my desktop, etc. Finally discovered that the camera height has to be very low, about rail height. The lens needs to be focusing on a slightly upward angle to get the proper focus on pupil and eyeglasses. I set up on the shots and took the pictures with the remote.
I processed in Photoshop, getting a clear, full scene shot for each setup, plus a crop of just the face. I took those in, and they reviewed them and had me emulate lining up a shot using a desk in the shop. They discussed it for a while.
They finally recommended a regular, round shaped frame with adjustable nose pads. They said they were thinking of making a minor adjustment to the optical center, but since some shots require a more upright position, they didn’t want to adjust the optical center more than a fraction. I think they may have decided to use my normal measurements for the location of the optical center.
I ordered what they recommended. When they arrived, they adjusted the nose pads such that the frame sits a bit higher on my face. I love it. I can get in position for a table length shot with chin close to the cue, and I can see clearly. I can stand almost upright for a jump shot with perfect focus.
I only wear these when playing, but I could wear them out and about just fine.
These guys cost a fortune, but they must have spent 4 hours all said and done getting regular distance, computer & desk distance, reading and speciality for pool. Worth it to me.
