Thirdly, you should not read for a long time without the rest which will make the eye muscles so tired. After remembering these tips, you should prepare eye drops to make the eyes moisture or you can eat food with vitamine C to be helpful for the eyes.
Yes, I think reading too much is bad for your eye health. As you are reading for a long time, your eyes will feel tired. If you donâ€™t give them the enough time to have a rest, they may lead to many other eyes diseases, such as the dry eyes. On the other hand, when you have read for a long time, your eyes have to focus on the small items. In this way, it will lead to the high eye pressure and finally they can damage your eyes. Anyway, you should not be supposed to be reading for a long time. Reading in a certain time and then you can go outside to relax. It will be good for your eye health.
