Can Reading in the Dark Affect Vision?
Youāve probably heard this warning before: āDonāt read in the darkāyouāll ruin your eyes!ā But is there any truth to this age-old advice? At OptoDoc, weāre here to clear up the facts about your eye health and reading habits.
The Myth vs. The Reality
Reading in low light doesnāt permanently damage your eyesābut it can cause temporary discomfort and eye strain.
In dim lighting, your eyes have to work harder to focus, which may lead to symptoms like:
- š Eye fatigue
- š£ Headaches
- šµāš« Blurry vision (temporarily)
- š§ Dry or watery eyes
Once you return to better lighting or give your eyes a break, these symptoms typically go away.
