The objective isn't to make a wooded course look artificially bright or dramatically different. It's to provide a clearer, more balanced view so you can better interpret what is already there.
Whether you are golfing, playing pickleball, disc golfing, skiing, cycling, or simply spending time outdoors, glare can hide critical details that your eyes rely on to interpret the world around you.
Terrain is defined by contrast. The difference between grass, dirt, roots, rocks, and elevation changes creates the visual cues your brain uses to understand the course.
