- Are computer screens harmful to the eyes?
There is no scientific evidence that computer screens are harmful to the eyes. However, as computer use increases, complaints of eye discomfort and fatigue increase, and such a concern rightfully arises.
In all studies, under normal conditions, harmful levels of ionizing radiation (X-rays) from computer screens (X-rays) or It was not possible to detect non-ionizing radiation (ultraviolet). For example, the amount of ultraviolet released from computer screens is much less than that released from a simple fluorescent light bulb. It does not have any harmful radiation effects even if used throughout life.
- Does computer use cause eye fatigue?
Yes. Those who use computers extensively. There may be redness, watering, dryness, fatigue and a feeling of heaviness in the eyes. Headache and backache may occur. These complaints can be reduced by arranging working conditions and providing glasses when necessary. Eye fatigue is an annoying condition, but it does not require us to give up using the computer. The cause of fatigue needs to be investigated. Your ophthalmologist can help you with this.
- How to prevent eye strain?
The computer screen should be slightly away from normal reading distance. The top edge of the computer screen should be at or slightly below eye level. If it is read from somewhere and written to the computer, the read material should be as close to the screen as possible. Thus, there is no need to move the head and adapt the eyes every time.
It is very important to properly illuminate the working room. In an incorrectly lit environment, reflections may occur from the screen and these reflections may disturb users. The workplace should not be too bright. If our face is turned to the window or shiny surfaces, it becomes difficult to see the screen. If it is not possible to change the lighting of the room, a screen filter can be used. Computer screens should be cleaned frequently with antistatic cloths as they collect a lot of dust.
Those who use computers should take regular breaks from their work. During intense computer use ut, head, and eyescan be tiring as they remain quite still. In those who use computers intensively, most of the complaints are caused by inactivity and sitting position. Additionally, during intense computer use, the eyes become dry because they blink less. By consciously blinking frequently or by dropping artificial tears from time to time, we can prevent drying and reduce complaints of burning in the eyes.
People who normally wear glasses for close-up use may need to readjust their glasses according to the screen distance if they use computers intensively.
Various problems, such as the causes of your complaints and unrecognized eye defects, can be diagnosed by the ophthalmologist during the examination. Your ophthalmologist will decide what needs to be done for treatment.
