An H3-antihistamine is a classification of drugs used to inhibit the action of histamine at the H3 receptor. H3 receptors are primarily found in the brain and are inhibitory autoreceptors located on histaminergic nerve terminals, which modulate the release of histamine.
Burning paper requires 1 watt (1000 mW), which is more than what most laser pointers can achieve without modifications For comparison: Popping balloons or lighting matches râ¦equires roughly 100 mW (which is the high end mW range of most commonly found laser pointers) Note: laser pointers anywhere near 100 mW and up are very dangerous to the eyes and ...
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.
