Technology is a part of everyday living and as we evolve to include this addition to our generation it is important to be sensible.
Sometimes it is difficult to monitor how long we sit in front of a screen. But now with smart phones it is not only our computers we spend quality time with but also our phones.
It is advisable then to consider the impact a screen has on our eyes. Therefore it is sensible to consider moving away from the screen every 20 minutes or so.
It is also a good idea to spend some time outside in the sunshine, wind or rain to give our eyes the break they need from the technology we push upon them.
Be sensible and protect your eyesight.
