Loss of limb(s) is defined as total and irrecoverable loss of: (a) sight of both eyes or the actual loss by physical separation of the two entire hands or two entire feet or of one entire hand and one entire foot or of such loss of sight of one eye and such loss of one entire hand or one eye and such loss of one entire hand or one entire foot. The loss of sight must be total and irrecoverable, hence blind for all practical purposes does not satisfy the definitions, but claims are admissible if vision has become so impaired that it is impossible to recognize objects, although the difference between darkness and light can be distinguished. It is also to be noted that loss of limbs include loss of use of limbs i.e., eyes are there intact but loss of sight is lost due to accident. (b) use of two hands or two feet or of one hand and one foot or of such loss of sight of one eye and such loss of use of one hand or one foot of the insured.
