Viewing computer screens for hours can affect more than your eyes. Most screens are backlit with blue light, which can interfere with your sleep cycle. A Boston, Massachusetts group of researchers did a study on the effects of reading on a tablet before bedtime versus reading a printed book before bed.
The group that read on a backlit device took ten minutes longer to fall asleep and didn’t sleep as deeply as the group that read printed pages. The researchers believe that the blue wavelengths electronic screens emit interfere with the production of melatonin, a sleep-promoting hormone. Consequently, those using screens don’t feel sleepy, so they stay up late and have trouble when they finally go to bed.
If you stay up late using a tablet or a computer, and then you don’t sleep well, you’ll only be contributing to your eyes’ dryness, strain, and discomfort, along with the other adverse effects of sleep deprivation.

The Colorimetry test is best suited for people who work for long hours on computers using spreadsheets and MS Word. White as the default background colour is not always the best for our eyes. Colorimetry is an individualised test to assess which colour is the best suited for your eyes. The test results are provided so that you may adjust your computer’s colour settings to best suit your individual need.
Computers project strong light directly into your eyes and you can suffer from ‘pattern glare’ or ‘visual stress’. Your eyes may tire quickly and you could experience one or more of the following symptoms.
