Answer 1 is incorrect because overhead or ceiling lights cause glare or shadows. Answer 2 is correct because glaucoma causes tunnel vision (loss of peripheral vision) and low vision. The client needs increased light, and sees best in natural lighting (sunlight). Fluorescent lighting does not produce glare and reduces shadows. A task light that can be directed is helpful. Answer 3 is incorrect because bright lights will cause glare and impair vision. Answer 4 is incorrect because the client needs increased lighting and preferably natural light, not dim lighting.
