Effects of Lighting and Daylighting on Performance

Most patients self-report their vision quality is quite poor – in poor ranges, over 90 percent (slide 49). And important to you is when we ask them, what kind of affect does lighting have on your performance activities? Close to 70 percent say it has a major effect. Lighting is one of the biggest problems. Over 20 percent say moderate effect and only 11 percent say it has no effect. So lighting is a very important consideration.

Question by [Participant]: Day lighting?

Response by Bob Massof: Yeah, daylight – both too much and too little. Too much light and they tend to wash out from this glare. Too little light their sensitivity is reduced and what might look like mood lighting to the average person can be a funhouse.
