Does a dental curing light cause night blindness?

No, a dental curing light does not cause night blindness. Night blindness, or nyctalopia, is typically caused by retinal issues, vitamin A deficiency, or certain eye conditions, and is not related to dental procedures. Dental curing lights emit specific wavelengths of light to harden dental materials, but they do not have any known effect on night vision or overall eye health. However, it's always advisable to wear protective eyewear during dental treatments to safeguard against bright lights.
