I have a prescription that requires progressive lenses for everyday wear. My long time OD, also a golfer, explained I just need single vision lenses (or contacts - he said just wear one lense in one eye). This was after I complained the progressives on the course were causing problems with solid striking of the ball. What an improvement!
Fast forward...I buy inexpensive frames and lenses from 39dollarglasses.com in a choice of frames I can wear in the office, casually, or on the golf course. With the sunglass tinting, I'm getting a very functional set of glasses for usually around $60-70 including priority mail 2-3 day delivery. And their customer service is off the charts good when there was a problem with only one order I've placed.
