I use the putting glasses in my indoor putting setup in my home . I was surprised at how far off my eyes were off the ball.
These are excellent to help you keep you head still. Had no idea how much it moves around, or how varied is my head motion on the aimline.

These glasses are well worth the cost. I have spent years tinkering with my stroke to cure a frequent slight pull due to closing the club face, and a lot of missed putts. Helped with eye alignment first, and that forced me to adjust my stance. Once there, I instantly discovered that I was moving my head, consistently. Took a lot of will power, but then sank 10 straight in the small hole, 2 to 8 feet!
Really helpful for 3 to 8 foot par saves
