| Abstract: |
Compact eye goggles for protection against laser and other high intensity light radiation or energy and having a pair of eye cups which are worn without discomfort over the respective eye balls, lids and lashes of the eyes of the wearer. Should the user wear spectacles, the goggles are worn under the glasses. The cups introduce no distortion of the optical path and can be worn by people with various eye corrections. The cups are each partially hemispherical with rounded corners to snugly fit the user's face without interfering with vision, forward or peripheral.

Show all 5 claims |
I claim:
1. An eye goggle for protection against laser and other optical radiation, comprising
- a pair of individual optical material segmental portions of a spherical surface, each of said segmental portions having a major chordal length in excess of a respective minor chordal length orthogonal thereto, said major chordal length approaching substantially twice the radius of curvature of said spherical surface, said material having means for absorbing intense light energy, and
- single elastic means connecting said segmental portions to each other and for attaching said segmental portions to predetermined objects, said elastic means being slidably secured to each of said spherical segmental portions, said connecting and attaching means includes means for adjustment of said spherical segmental portions relative thereto and to each other.
