Myth: Reading in dim light will worsen your vision
Fact: Although dim lighting will not adversely affect your eyesight, it will tire your eyes out more quickly. The best way to position a reading light is to have it shine directly onto the page, not over your shoulder. A desk lamp with an opaque shade pointing directly at the reading material is the best possible arrangement. A light that shines over your shoulder will cause a glare, making it more difficult to see the reading material.
