wherein the region that is transparent for electromagnetic radiation with the wavelength range outside the visible range is made of a material that is transparent for visible light coated with a material that is opaque to visible light.

2. The apparatus according to claim 1 , wherein the first eye piece and the second eye piece are unconnected for individual and independent positioning at the respective left and right eyes.

3. The apparatus according to claim 1 , at least one of the first eye piece and the second eye piece comprises an adhesive surface for adhesively securing the at least one of the first eye piece and the second eye piece to a skin surface of the human.

4. The apparatus according to claim 3 , wherein the adhesive surface is on a flexible material.

5. The apparatus according to claim 3 , wherein the adhesive surface comprises a layer of adhesive tape that is secured to the at least one of the first eye piece and the second eye piece.

6. The apparatus according to claim 5 , wherein the adhesive surface is a part of a double-sided tape, the double-sided tape having an additional adhesive surface adhering to a posterior surface of the at least one of the first eye piece and the second eye piece.

7. The apparatus according to claim 1 , wherein the region that is transparent for electromagnetic radiation with the wavelength range outside the visible range comprises at least a portion of a surface that covers the left eye or the right eye.

8. The apparatus according to claim 1 , wherein the at least one of the first eye piece and the second eye piece with the region that is transparent for electromagnetic radiation with the wavelength range outside the visible range, comprises a frame with an aperture for accommodation of a window that defines the region, the frame being made of a material that is different from a material of the window.

9. The apparatus according to claim 1 , wherein at least one of the first eye piece and the second eye piece comprises a peripheral flange that is shaped to conform to a shape of an orbital rim of the left eye or the right eye.

10. The apparatus according to claim 1 , wherein at least one of the first eye piece and the second eye piece comprises a transversal portion that is positioned in front of one of the eyes when worn by the human, and an annular peripheral wall that surrounds the transversal portion and extends rearwardly therefrom, and a peripheral flange surrounding the peripheral wall and shaped to conform to a shape of an orbital rim of one of the eyes.

11. The apparatus according to claim 1 , further comprising a nose piece that interconnects the first eye piece and the second eye piece, and that is configured for fitting across a nose of the human.

12. The apparatus according to claim 11 , further comprising a head strap that interconnects the first eye piece and the second eye piece, and that is configured for fitting around a rear of a head of the human.

13. The apparatus of claim 12 , wherein at least one of the first eye piece and the second eye piece comprises a peripheral flange that is shaped to conform to a shape of an orbital rim of the left eye or the right eye.

14. The apparatus of claim 11 , wherein at least one of the first eye piece and the second eye piece comprises a peripheral flange that is shaped to conform to a shape of an orbital rim of the left eye or the right eye.

15. The apparatus according to claim 1 , wherein the region has a transmittance of more than 50% of infrared light in a wavelength range from 850-1100 nm.

16. A device for worn above a shoulder of a user, comprising:

a structure;

at least one camera coupled to the structure; and

the apparatus of claim 1 ;

wherein the first eye piece and the second eye piece of the apparatus are coupled to the structure.

17. The device according to claim 16 , wherein the structure comprises a helmet.

18. The device according to claim 16 , wherein the structure comprises a mask.

19. The device according to claim 16 , wherein the structure comprises a frame of a glasses or goggles.

20. A method of determining an eye movement, comprising:

providing an apparatus having a first eye piece a second eye piece, and a camera, wherein at least one of the first eye piece and the second eye piece comprises a region that is transparent for electromagnetic radiation with a wavelength range outside a visible range, wherein the region that is transparent for electromagnetic radiation with the wavelength range outside the visible range is made of a material that is transparent for visible light coated with a material that is opaque to visible light;

preventing visible light from reaching eyes of a human using the first eye piece and the second eye piece; and

tracking a movement of at least one of the eyes using the camera.
