SAEDNEWS: The position of a desk lamp can influence visual comfort and fatigue during reading or studying. Proper lighting can reduce shadows, glare, and unnecessary eye strain, making long study sessions more comfortable.
According to SAEDNEWS, the position of a desk lamp can affect how comfortable the eyes feel during reading and studying. A poorly placed lamp may create shadows across books or notebooks, forcing the eyes to work harder to see the text clearly. Good lighting should illuminate the study area evenly without creating strong contrasts.

The direction of the light is also important. For people who write with their right hand, placing the lamp on the left side can help reduce shadows from the writing hand. For left-handed writers, positioning the lamp on the right side can provide similar benefits. The goal is to keep the page well illuminated while preventing the hand or body from blocking the light.
Glare can be another source of discomfort. If the lamp shines directly into the eyes or reflects strongly from glossy pages or a computer screen, it may cause visual discomfort and make concentration more difficult. Adjusting the lamp so that the light falls on the reading surface rather than directly toward the eyes can create a more comfortable environment.
A suitable lamp position can therefore support more comfortable study sessions, especially when reading for extended periods. Keeping the light source at an appropriate angle, avoiding harsh shadows, and maintaining balanced room lighting can reduce unnecessary visual strain. However, regular breaks and a comfortable reading distance are also important for reducing fatigue.
