Abstract

A device for improved vision into or out of at least one eye of a subject. The device comprises an enclosing vessel for holding one or more lenses in front one or two eyes of the subject and for holding a substance whose refractive index is matched to the refractive index of the cornea. The vessel is adapted to seal the substance to the face around the eye or eyes of the subject thereby allowing focusing into or out of the eye or eyes.

Claims

1. A device for improved vision into or out of at least one eye of a subject, the device comprising:

at least one enclosing vessel for holding at least one lens in front of at least one eye of the subject and for holding a substance whose refractive index is matched to the refractive index of the cornea,

wherein the vessel is adapted to seal the substance to the face around said at least one eye of the subject;

thereby allowing focusing into or out of said at least one eye or both.

2. The device of claim 1, provided with at least one strap for restraining the device on the face of the subject.

3. The device of claim 1, wherein said at least one enclosing vessel comprises two vessels, each vessel provided with a lens.

4. The device of claim 1, incorporated in a helmet provided with at least one restraining strap.

5. The device of claim 1, provided with an adapter for attaching the device to a separate device.

6. The device of claim 1, wherein the optical properties of the lens are variable.

7. The device of claim 1, further provided with at least one external optical element adapted to be placed in front of the device.

8. The device of claim 1, wherein said at least one lens is selected from a group of optical systems consisting of a single lens, a doublet, a triplet, a diffractive lens, a variable index lens a compound lens, flexible lens, lens with anti-reflection coating, mirrors, or a combination thereof.

9. The device of claim 1, provided with an adjustment mechanism for orienting and displacing said at least one lens.

10. The device of claim 1, wherein the vessel has at least one opening in it through which the substance can be changed or modified or added or removed.

11. The device of claim 1, further provided with at least one transparent partition so as to allow the vessel to separately hold substances of different optical characteristics.

12. The device of claim 1, further provided with a light source for illuminating said at least one eye.

13. The device of claim 1, provided with at least one wave guide for guiding light into said at least one eye.

14. The device of claim 1, wherein the vessel is flexible.

15. A method for improving vision into or out of at least one eye of a subject, the method comprising:

providing a device comprising at least one enclosing vessel for holding at least one lens in front of at least one eye of the subject;

providing within the vessel at least one substance whose refractive index is matched to the refractive index of the cornea,

sealing the vessel to the face around said at least one eye of the subject;

thereby allowing focusing into or out of said at least one eye or both.

16. The method of claim 15, further comprising strapping the vessel to the face of the subject.

17. The method of claim 15, further comprising displacing or tilting said at least one lens.

18. The method of claim 15, further comprising placing one or more transparent substances separately in the vessel.

19. The method of claim 15, wherein the vessel is flexible, further comprising changing pressure within the vessel to change at least one optical property of the device.

20. The method of claim 15, wherein matching the refractive index of the substance to the refractive index of the cornea comprises partially or fully replacing or mixing the substance within the vessel with another substance of different optical properties or for nutritional or medical purposes.

21. The method of claim 15, wherein said at least one lens is flexible, further comprising applying pressure on or around said at least one lens to change its optical properties.

22. The method of claim 15, used in conjunction with ocular measurements or imaging.

23. The method of claim 15, used in conjunction with ocular surgery or procedure.

24. The method of claim 15, further comprising correcting further aberrations using an adaptive optics system, the system comprising at least one component from a group of components consisting of a wave front sensor, a wave front modulator, and a servo controller.
