[ EN ]

I/We claim:

1. An Eyewear adapted for defogging in order to protect a user's eyes during surgery application, the eyewear comprising a frame and a pair of ear pieces coupled to the frame, the ear pieces configured to assist in holding the eyewear on a user's head, the eyewear further comprising a heating element characterized in that the eyewear comprises:

a Nichrome 0.3 15W/ah resistance wire (N80CR20) in a groove in an overhang, attached to the upper rim of the frame of eye glasses connected with a circuitry including a power source, a voltage regulator, a rocker/micro switch and a plurality of connection wires; wherein the said Nichrome wire is preferably of diameter and length of 0.2 mm and 15 cm respectively which is used as a heating element of glass surface.

2. The eyewear as claimed in claim 1, wherein the power source is of a rating of (7.8 V, 2600 mAh )

3. The eyewear as claimed in claim 1, wherein the said voltage regulator and current limiter LM2596 (3) is used in order to limit the flow of maximum current from the batteries and thereby avoid overheating of Nichrome wire in order to protect glasses from melting at the point of contact with Nichrome wire.

4. The eyewear as claimed in claim 1, wherein the said voltage regulator and current limiter LM2596 (3) is configured to supply around 1.65 A current from source with a voltage of 2V, enough to defog whole glass.

5. The eyewear as claimed in claim 1, wherein the said connecting wire has diameter of 0.5 mm
