Eye exams should be a regular occurrence to maintain good eyesight. As you age your eyes should get looked at more often. Aging brings on an increased risk for issues such as glaucoma, cataracts and deteriorating eye sight. Letting an optometrist check your eyes closely will help prevent problems or catch them in advance.
Rest your eyes. If you spend long periods of time looking at your computer or focusing on one thing, it can be easy to forget to blink. This causes your eyes to fatigue. Reduce eye strain by looking away every 20 minutes for about twenty seconds. This can help your eyes.
