For many years, I have concetrated soley on the bottom yellow when racing. I am nearly 60 now, and can no longer see the bulb until it flashes. After dark, once I pre-stage, all I can see is a dark hole where the bulbs are. Is there any glasses that would improve my vision after dark? Or am I now limited to daytime racing? I don't think that I am the only one that has had to face this day. Thanks for any replies.
