Abstract
A motorcycle goggle includes a supply magazine and a take-up magazine mounted to opposite sides of a goggle frame and contain a transparent film which moves across the outer surface of a main lens to protect the main lens from mud or external matter. The main lens includes a plurality of projections attached to the lens to raise the transparent film off the main lens surface. The projections can be formed by transparent ink droplets which are printed by a silk screen process onto the outer surface of the main lens, and consist in one form of two types of ink forming each raised ink droplet.
