Everybodies eyeballs are different. Sometimes it just takes a little eyestrain to send one particular persons eyes over the edge. We were not all born with some bionic eyeball
Dim light can cause permanent eye damage...ask Abraham Lincoln, he read and studied law by candlelight for decades and it permanently damaged his eyes beyond repair, this is fact
Are you serious? "Abraham Lincoln?"
That's your evidence?
I know that the ability to think critically is not the most valued commodity these days, but come on. Just because some eighth grade history teacher told you Lincoln ruined his eyesight by reading by candlelight, doesn't make it so. Do you also believe George Washington really chopped down that cherry tree?
If I had to take a wild guess, I'd say that the science of ophthalmology is a little more advanced now than it was back in Lincoln's day. So even if Lincoln had been diagnosed by a doctor who concluded that his poor eyesight was due to candlelight (it sounds absurd just typing that!) - that don't make it so. There are a million things that could have permanently degraded his vision, many of them hereditary. Candlelight ... isn't one of them.
From the American Academy of Ophthalmology's webpage on myths:
"Reading in dim light is harmful to your eyes." True or False?
False. Using your eyes in dim light does not damage them. For centuries, all nighttime reading and sewing was done by candlelight or with gas or kerosene lamps. However, good lighting does make reading easier and can prevent eye fatigue.

It has nothing to do with "bionic eyes."
We all have things we believe that aren't true. Maybe our parents taught them to us, or our friends, or the media or whatever. I have them, and you have them. We all do. But it's important to question those beliefs, to ask what really lies behind them. Is there any factual evidence for them? Or do we just believe them ... because we believe them?
