ARE DESK LAMPS GOOD OR BAD FOR YOUR EYES?
Most people have heard the warning that dim light can harm our eyes and that we should turn on an overhead light when reading. But a study published in the British Medical Journal in 2007 debunked this myth by stating that reading in low light does not damage eyes, although it may cause some eye strain.
Many people use desk lamps to read or to give them extra light when they are working at the computer. A more direct light seems a much better option for reading. But while the desk lamp itself is not harmful to the eyes, there are ways to use desk lamps effectively to cut down on stressed eyes.
So while dim lighting does not cause bad eyesight, it just make eyes tired, particularly as we age.
A desk lamp is best utilised when it has an opaque shade and the light is pointed directly at the material being read. If it is placed over the shoulder, the light can create a glare on the material and cause eyestrain.
