Lazy Eye and Strabismus are not the same condition.
Amblyopia, commonly known as lazy eye, is the eye condition noted by reduced vision not correctable by glasses or contact lenses and is not due to any eye disease.
Many people make the mistake of saying that a person who has a crossed or turned eye (strabismus) has a "lazy eye," but lazy eye (amblyopia) and strabismus are not the same condition.
In computer programming, lazy evaluation, also called delayed evaluation, is the technique of delaying a computation until such time as the result of the computation is known to be needed.
The benefits of lazy evaluation include: performance increases due to avoiding unnecessary calculations, avoiding error conditions in the evaluation of compound expressions, the ability to construct infinite data structures, and the ability to define control structures as regular functions rather than built-in primitives.
Another example of laziness in modern computer systems is copy-on-write page allocation or demand paging, where memory is allocated only when a value is stored in those memory is accessed.
