Lighting

Lighting plays an important role in how we see.

Lighting during eye exams

"That said, according to international ophthalmic standards (aka ISO 8596:2017), the luminance or brightness should be between 80-320 lux uniformly across the exam room during a proper visual acuity exam. This includes the eye chart and the room itself.

As a point of comparison, 350-375 lux is equivalent to a 25-watt incandescent bulb at full brightness. So yeah, that is pretty darn dim."
