A dim light can cause retinal damage if exposure is sufficiently prolonged
the verdict
SUPPORTED
the evidence backs this
confidence 88/100
Multiple scientific studies demonstrate that prolonged exposure to even relatively low levels or intensities of light can induce irreversible retinal damage and photoreceptor degeneration over time.

Retinal damage after prolonged exposure to visible light. A light and electron microscopic study
1972 · cited by 85
This classic study demonstrates that prolonged exposure to low-intensity visible light leads to irreversible degeneration of retinal photoreceptor cells.
