it won't be blind immediately. but if the fish or the coming generations are left for a long period and do not seen the light for many years, they can go blind. this is called evolution.
yes
from high speed dives into the ocean for fish
Well, no but they are a lot better with them. For your fish, not for show, if you have gold fish, if you don't put a light in they will go silver. This is because of the lack of light.
I believe not because farmers usually lock chickens in the farm with no light and they dont go blind ...
intense light can make you go blind. The light may cause extreme heat and vaporize people.
yes if you stare to long u can go blind
No a frog cannot go blind in high temperatures because frogs are different from amphibians because they do not have a tail. Frogs typically have tiny eyes and are nearly blind, although they can tell light from dark.
Some kinds of fish do. That's why fishermen can sometimes lure fish to the hook by shining a light into the water. This is generally considered bad form, like cheating.
that depends what you want to do with the tank if you want a planted tank then dont go with a LED light inless the plants are very hardy and dont require a lot of light. if its just for fish go with the LED light. i have a LED light on my fish tank and my fish are doing great. i dont have any plants but i might get some hardy, low light ones. LED also saves energy
everything can go blind in a waycan you go blind if you stay in the darkness?yes
so they do not get too hot and die or look at the sun and go blind.
