Try this...
Specialty frames are all fine and dandy, but may or may not really help based on your particular prescription, so...
IF, and I do mean IF, you are, as I am, slightly aging in the eyes and/or slightly to significantly presbyopic, you must try this. I predict that it will be worth it, and at least worth the cost of one prescription as an experiment, even if it is with the various frames recommended here.
Ingredients:
1 - camera tripod, telescoping, any brand
1 - new to slightly used solid, preferably a 5-ball
1 - new to slightly used stripe, preferably a 11-ball or a 12-ball
1 - piece masking tape, preferably wide, about 6-8 inches long
1 - cooperative optometrist/opthamologist, preferably your regular provider
1. Read the entire procedure before proceeding to step #2.
2. Book an appointment with your provider.
3. Take the first four ingredients to the appointment with you.
4. After discussing your desires and the procedure with your provider, set up the tripod so the mounting platform is six feet from the provider's apparatus (for play on 7 foot tables) or 7-8 feet from the provider's apparatus (for play on 8-9 foot tables). The level of the platform sould be about a foot below the lenses of the provider's apparatus.
5. Loop the masking tape to form a double-sided sticky loop. Place the loop on the tripod platform.
6. Place the solid and stripe on the tape on the platform, with about a half an inch of space between them. Number of the solid towards the provider's apparatus, and a point about halfway between the number and the edge of the stripe likewise.
6a. (Most providers offices will have overhead flourescent lights, which should be left on and will adequately simulate table lighting. If you do advance research and discover this is not the case, you need to bring a second tripod, portable bright flouescent desk lamp, extension cord and more tape.)
7. Have your provider dial you on the balls for SINGLE VISION lenses.
8. IMPORTANT!!! When measuring for placement of the center of focus, have the provider/provider's assistant measure you while in a typical shooting stance. THAT is what makes the specialty frames not so necessary.
9. Fill the presecription. If not using a source listed here (which may be helpful, but not totally necessary,), get the BIGGEST frames you can.
10. Pick up prescription. Go to pool hall.
11. Attempt to rack the balls. Work on getting over the vertigo/nausea while racking the first few times. (Especially if you normally wear multi-vision. It's freeeeeeeaky, but I assure you the table is really not moving.)
12. Practice a little with the new frames.
13. Kick ass.
14. Take names.
15. Come back here and tell me if you wasted money or if you owe me one. I'll bet on the latter.
