Leica 723777 Laser Glasses for Distance Meters

At least doubles the distance you can see the laser beam. Also makes the beam more visible in sunlight. Only drawback cuts down light drastically, but that's not a big problem in sunlight, which is the main problem with viewing a laser beam at target.

product was as described and seems to do the job as needed in different weather conditions. Have had no problems yet seeing laser with glasses on.
