Myth busted: Reading in the dark does not permanently damage your eyes — but it can make them work overtime! As autumn sets in and evenings get longer (hello, cosy reading sessions), let's clear up this common misconception with facts.
Contrary to what many believe, dim lighting doesn't cause lasting harm like nearsightedness or vision loss — extensive studies by eye health organisations have found no evidence of permanent structural changes. Instead, it leads to temporary eye strain: your pupils dilate to let in more light, forcing your eye muscles to work harder, which can result in fatigue, headaches, dryness, blurred vision, or even watery eyes as your body overcompensates.
These symptoms typically resolve with rest or better lighting, but chronic strain may exacerbate underlying conditions such as dry eye syndrome.
Why does the myth persist? It stems from outdated advice, but modern research emphasises comfort: aim for even, glare-free illumination (e.g., 300-500 lux for reading) to reduce ciliary muscle stress and maintain tear film stability.
At Dry Eye Clinic, if strain lingers, it could signal meibomian gland dysfunction or other treatable causes — we use advanced diagnostics to help.
Pro tip: Take 20-20-20 breaks (every 20 mins, look 20 ft away for 20 secs) to ease the load.
