At night, humans can use flashlights to spot animals that possess tapetum lucida by causing a phenomenon called eye shine.. Eye shine is the iridescent glow observed in animals when light is shone into their eyes, which floods the eye with light that is then reflected by the tapetum lucidum.
You cannot physically damage a person's eye with a laser pointer. You can however, decrease the activity in the inner eye which relays a signal (blindness) after a period of t â¦ ime while staring into the laser.It is not strong enough to damage, but bright enough to cause dysfunction of your pupil.he laser diode in laser pointers can't change frequency, so the diode itself has to be switched. Other colors can be mixed together though, so yellow â¦ can be achieved by a red diode and a green diode in the same casing.
