Alternatively the lamp might not be meant as a source of light, but rather as a guide through darkness, just as the eye is a guide through life.

Tears are a clear liquid secreted by the lacrimal glands (tear gland) found in the eyes of all land mammals. [1] Tears are made up of water, electrolytes, proteins, lipids, and mucins that form layers on the surface of eyes. [2] The different types of tears—basal, reflex, and emotional—vary significantly in composition. [2]
The young human eye can change focus from distance (infinity) to as near as 6.5 cm from the eye. [32] [33] This dramatic change in focal power of the eye of approximately 15 dioptres (the reciprocal of focal length in metres) occurs as a consequence of a reduction in zonular tension induced by ciliary muscle contraction.
While some bottled water is from a spring or filtration system, research shows that nearly 65% of bottled water sold in the U.S. comes from municipal tap water. But Rumpler says there can be ...

If sparkling water is your beverage of choice, rest assured that it is a valid way to stay hydrated. Just do your homework and buy one that doesn’t contain loads of chemical flavoring—and don ...
Accordingly, deeper water hyperiids, where the light against which the silhouettes must be compared is dimmer, have larger "upper-eyes", and may lose the lower portion of their eyes altogether. [40] In the giant Antarctic isopod Glyptonotus a small ventral compound eye is physically completely separated from the much larger dorsal compound eye ...
The pupil of the human eye can range in size from 2 mm to over 8 mm to adapt to the environment. The human eye can detect a luminance from 10 −6 cd/m 2, or one millionth (0.000001) of a candela per square meter to 10 8 cd/m 2 or one hundred million (100,000,000) candelas per square meter.
