Optical apparatus and method
First Claim
1. An optical apparatus comprising:
- a liquid lens;
a liquid pump for adjusting the pressure of liquid in a cavity of said lens;
a closeable tube for interconnecting said cavity and said liquid pump, said pump permitting the flow of liquid therebetween;
a closure for closing the tube when the pressure of liquid in said cavity attains a desired value, whereby to render the lens subsequently non-adjustable; and
a frame including at least one elongate recess for receiving said closeable tube after closing thereof, wherein at least a portion of said closeable tube is outside the frame prior to being received within said elongate recess.

Abstract
In the field of eyesight correction, there is a need for "universal" spectacles that can be tailored in situ to suit an individual'"'"'s requirements. The disclosure relates to an apparatus, which may be in the form of a pair of spectacles (1) including one or more liquid lenses (11a, 11b). The apparatus also includes a sealable duct (24) and a pump (e.g., a syringe) for adjusting the pressure of liquid in the liquid lens. In use, the apparatus is adjusted to provide eyesight correction for an individual. The duct (24) is then sealed, thereby rendering the apparatus subsequently non-adjustable and therefore permanently tailored to the requirements of the individual. The disclosure also relates to an apparatus in the form of a flexible membrane mirror.

13. A method of adjusting an apparatus for correcting defective eyesight, comprising the steps of:
-
(i) placing a pair of spectacles in front of a patient'"'"'s eye such that the eye receives light through a lens thereof, said pair of spectacles comprising; a first liquid lens; a second liquid lens; at least one liquid pump for adjusting the pressure of liquid in a cavity of said first liquid lens and said second liquid lens; at least one closeable tube for interconnecting said cavity and said at least one liquid pump permitting the flow of liquid therebetween; at least one closure for closing said at least one closeable tube when the pressure of a liquid in said cavity attains a desired value, whereby to render said first liquid lens and said second liquid lens non-adjustable; and a frame including at least one elongate recess for receiving said closeable tube after closing thereof, wherein at least a portion of said closeable tube is outside of said frame prior to being received within said elongate recess; (ii) operating the pump of the apparatus until a patient sees an optimum clarity image; (iii) closing the tube of the pair of spectacles; and (iv) detaching the pump from the apparatus.

14. A method of adjusting an apparatus for correcting defective eyesight, comprising the steps of:
-
(i) placing a pair of spectacles in front of a patient'"'"'s eyes, said pair of spectacles having a first liquid lens; a second liquid lens; at least one liquid pump for adjusting the pressure of liquid in a cavity of said first liquid lens and said second liquid lens; at least one closeable tube for interconnecting said cavity and said at least one liquid pump permitting the flow of liquid therebetween; at least one closure for closing said at least one closeable tube when the pressure of a liquid in said cavity attains a desired value, whereby to render said first liquid lens and said second liquid lens non-adjustable; and a frame including at least one elongate recess for receiving said closeable tube after closing thereof, wherein at least a portion of said closeable tube is outside of said frame prior to being received within said elongate recess; (ii) allowing each of the patient'"'"'s eyes to receive light via said respective liquid lens; (iii) obscuring a pupil of a first of the patient'"'"'s eyes; (iv) operating a pump of a lens associated with a second of the patient'"'"'s eyes until the second eye sees an image of optimum clarity; (v) closing the closeable tube; (vi) uncovering the pupil of the first eye; (vii) uncovering the pupil of the patient'"'"'s second eye; (viii) repeating steps (iii) and (iv) with respect to the patient'"'"'s second eye; and (ix) detaching the pump from the apparatus. - View Dependent Claims (15)
