## Abstract

A luminant safety eyewear device with improved lighting may feature a central light source with color changing lenses. The lenses may be manually or electromagnetically manipulated into position. Three lenses may be provided to change color emitted from white, to red, to green and/or blue. Alternately, multiple light sources or a color-changing light source may be utilized either with or without multiple lenses.

## Claims

### Claim 1

A luminant safety eyewear apparatus comprising:
a frame, earpieces, and safety lenses, with a bridge located in the frame between the safety lenses;
a central light source located over the bridge of the frame;
a rechargeable power source for the light source; and
at least one colored lens movable over the light source and stowed when not in use by sliding into the frame.

### Claim 2 (depends on 1)

The luminant safety eyewear of claim 1, the at least one colored lens being three such lenses, nested over each other when stowed.

### Claim 3 (depends on 2)

The luminant safety eyewear of claim 2, the lenses being manually manipulated.

### Claim 4 (depends on 2)

The luminant safety eyewear of claim 2, the lenses being electromechanically actuated.

### Claim 5

A luminant safety eyewear apparatus comprising:
a frame, earpieces, and safety lenses;
a central light source located over a bridge of the frame, said light source selectively emitting different wavelengths of light;
a rechargeable power source for the light source; and
a control switch.

### Claim 6 (depends on 5)

The luminant safety eyewear of claim 5, further comprising at least one lens located proximate the central light source.

### Claim 7 (depends on 6)

The luminant safety eyewear of claim 6, at least one lens being movable over the light source and stowed when not in use by sliding into the frame.

### Claim 8 (depends on 1)

The luminant safety eyewear of claim 1, the at least one lens being three such colored lenses, nested over each other when stowed.

### Claim 9 (depends on 2)

The luminant safety eyewear of claim 2, the at least one lens being manually manipulated.

### Claim 10 (depends on 2)

The luminant safety eyewear of claim 2, the at least one lens being electromechanically actuated.

### Claim 11 (depends on 5)

The luminant safety eyewear of claim 5, the central light source being a plurality of LED chips.

### Claim 12 (depends on 11)

The luminant safety eyewear of claim 11, each LED chip of the plurality of LED chips being capable of emitting different wavelengths of electromagnetic radiation.
