Dear capese,
It is difficult to fully answer your question without knowing more information. I would recommend using lights that help you see the best.

Most of this is wrong. If the patient has glare from cataracts bright lights should be avoided. However, this is usually not a problem unless they are driving toward the sun or driving at night.
