1. Computer users should take regular screen breaks, ideally every 30 minutes. During breaks, look to the distance or close your eyes for a few seconds in order to rest them.
2. People often find their eyes dry out because they blink less at a computer. To avoid this, try blinking every time you hit the return key.
3. The glands in our eyes can sometimes get blocked, which can contribute to dry eyes. To reduce this, cover your eyes with a hot flannel for a few minutes and then massage along the eye lids. Try to do this daily. Taking supplements such as good quality omega 3 oils can also help to improve tear function.
4. Some people find focusing on close-up tasks difficult. This may be due to slight weaknesses in our convergence eye muscles. Hold a pen around 40cm from your nose, then slowly move it closer until you can see it double. Do this three to four times then close your eyes for a few minutes or look in the distance to rest your eyes. Try to do this exercise little and often.
5. Hold some small text around 10-20cm away. It could be the page of a book or a food label, just make sure you can read it clearly. Then look at some text in the distance, maybe on a sign or the text/subtitles on the TV. Read one line of text close to you and then a line of text in the distance. Repeat this five to ten times. Once you have completed the exercise, rest your eyes for a few minutes by shutting them or looking in the distance.
Despite doubting the Madrid study’s findings, Qureshi says we should still set guidelines when using smartphones and tablets.
- Set your device to auto brightness.
- Hold your tablet or smartphone at arm’s length (or about 70cm) from your eyes.
- Make the font bigger to stop strain on the eyes.
- Only use the device for a couple of hours a day in one sitting. Then take a break and come back to it later.
