A night-vision optical device of the invention with controlled life expectancy contains a time measuring device built into the housing of the aforementioned device for measuring the accumulated time of active work of the device. In application to a night scope for a firearm, the device also contains a sensor, which is interlocked with activation of the scope and reacts on the shots produced from the firearm in general and separately on those shots produced during active work of the night-vision optics at nighttime. The aforementioned shots of both types are counted and stored in separate memory units. The night-time shots affects the life expectancy of the night-vision optics because of muzzle flashes which cause such devices as an image intensifier to work with an increased light load. The information obtained from the time measuring device and the shot counter makes it possible to timely receive a warning signal about the fact that the night optics or the entire firearm must be replaced.

1. A night-vision optical device having controlled life expectancy comprising:switching means for switching on or switching off said night-vision optical device; time measuring means installed on a firearm for use as a night vision optical sight for measuring the total accumulated time during which said night-vision optical device was switched on by said switching means; and means for counting the number of shots produced from said firearm when said night vision optical sight is activated by said switching means. 2. The night-vision optical device of claim 1, wherein said means for counting number of shots counts the total number of shots produced from said firearm irrespective of whether said night-vision optical device is activated or not.3. The night-vision optical device of claim 2, wherein night vision optical sight has a housing with a compartment inside said housing, said means for counting the number of shots produced from said firearm when said night vision optical sight is activated by said switching means, and said means for counting the total number of shots are installed in said compartment.4. The night-vision optical device of claim 2, wherein said means for counting the total number of shots is a piezo-sensor attached to said night vision optical sight.5. The night-vision optical device of claim 2, wherein said firearm has a direction of shooting, said compartment has a wall substantially perpendicular to said direction of shooting, said means for counting the total number of shots is a piezo-sensor attached to said wall.6. The night-vision optical device of claim 2, further comprising a first nonvolatile memory units for storing information about said total accumulated time during which said night-vision optical device was switched on by said switching means, a second nonvolatile memory unit for storing information about said number of shots produced from said firearm when said night vision optical sight is activated by said switching means, and a third nonvolatile memory unit for storing information about said total number of shots.7. The night-vision optical device of claim 5, further comprising a first nonvolatile memory units for storing information about said total accumulated time during which said night-vision optical device was switched on by said switching means, a second nonvolatile memory unit for storing information about said number of shots produced from said firearm when said night vision optical sight is activated by said switching means, and a third nonvolatile memory unit for storing information about said total number of shots.8. The night-vision optical device of claim 6, further comprising a data reading unit for selectively retrieving said information at least from one of said first nonvolatile memory unit, said second nonvolatile memory unit, and said third nonvolatile memory unit, said data reading unit having a display.9. The night-vision optical device of claim 8, wherein said data reading unit is connected to said first nonvolatile memory unit, said second nonvolatile memory unit, and said third nonvolatile memory unit via a remote control data transmission system.10. The night-vision optical device of claim 7, further comprising a data reading unit for selectively retrieving said information at least from one of said first nonvolatile memory unit, said second nonvolatile memory unit, and said third nonvolatile memory unit, said data reading unit having a display.11. The night-vision optical device of claim 10, wherein said data reading unit is connected to said first nonvolatile memory unit, said second nonvolatile memory unit, and said third nonvolatile memory unit via a remote control data transmission system.12. The night-vision optical device of claim 8, wherein said data reading unit is connected to said first nonvolatile memory unit, said second nonvolatile memory unit, and said third nonvolatile memory unit via a disconnectable connector.13. The night-vision optical device of 10, wherein said data reading unit is connected to said first nonvolatile memory unit, said second nonvolatile memory unit, and said third nonvolatile memory unit via a disconnectable connector.14. A method for controlling a life expectancy of a night vision optical device comprising the steps of:providing said night vision optical device with means for switching on or switching off said night-vision optical device and with time measuring means; measuring the total accumulated time during which said night-vision optical device was switched on by said switching means; and controlling the life expectancy of said night vision optical device by comparing said total accumulated time with a given value. 15. The method of claim 14, further comprising the steps installing said night vision optical device on a firearm for use as a night vision optical sight.16. The method of claim 15, further comprising the step of counting the number of shots produced from said firearm when said night vision optical sight is activated by said switching means.17. The method of claim 15, further comprising the step of counting the total number of shots produced from said firearm irrespective of whether said night-vision optical device is activated or not.18. The method of claim 16, further comprising the step of counting the total number of shots produced from said firearm irrespective of whether said night-vision optical device is activated or not.19. The method of claim 18, comprising the step of activating said means for measuring the total accumulated time simultaneously with switching on said night vision optical sight.20. The method of claim 19, comprising the step of memorizing total accumulated time, said total number of shots produced from said firearm irrespective of whether said night-vision optical device is activated or not, and said number of shots produced from said firearm when said night vision optical sight Is activated by said switching means in separate nonvolatile memory units for storage as memorized values, retrieving at least one of said memorized values, and determining the remaining resource of said life expectancy with at least one given value.
