| Proper light levels are essential for comfortable reading. But will reading in dim light ruin your eyes? The notion of this has been around for centuries, particularly since the time before electric light, where reading under dim light was common. Through much recent study, researchers have found that there is no conclusive evidence suggesting that reading in dim light will increase your chances of becoming nearsighted or farsighted. Some adverse effects of reading in dim light include headache, dizziness, and temporary blurred vision.The proper lighting level for comfortable reading is approximately 600 lux, or about the typical lighting level of a bright office. This can also be attained with a normal reading lamp or table lamp, placed about 2-3 feet away from the reader.Despite common myths, there is not enough evidence to determine whether nearsightedness is caused by anything outside of genetics. Some theories do exist, such as the common theory that doing “near work”, which includes reading up close for long periods of time, looking at objects from a short distance, or sitting too close to the TV, can lead to nearsightedness (myopia). Other theories include eating too much bread or rice products as a child, and foods rich in carbohydrates. While these theories may have some merit, the evidence is simply not conclusive. So while proper light levels are essential for the best reading environment, there is no true indication that reading in dim light will ruin your eyes. |  (Mag-Lite Black Finish 3 Diopter Magnifier Lamp Adjustable Desk Lamp) |
