Definitions:

Light Rays

Streams of photons that move in a straight line, visible to the human eye when they strike an object and are reflected.

Lens

A piece of transparent material, usually glass or plastic, that refracts or focuses light rays, used in glasses and optical instruments.

Critical Periods

Specific times during early development when the organism is particularly sensitive to certain environmental stimuli, which can have a lasting effect on later development.

Sensory Adaptation

The adjustment of sensory receptors to the level of stimulation they are exposed to, leading to decreased sensitivity with constant exposure.
