I highly recommend IQ Laser Vision.
" Nothing is more important to a sportscaster than getting the score right. But when I looked at the scoreboard at Dodger Stadium, I could never see the score. It was too blurry. All the numbers looked the same. It was a hassle and embarrassing, and I was always worried I'd get the score wrong on the radio. They eased my fears, and made me feel comfortable throughout the procedure. I highly recommend IQ Laser Vision. "
