Although reading in dim light is unwise because it may cause your eyes to feel tired or uncomfortable, it can't hurt your eyes. There really is very little you can do that will permanently damage your eyes. Similarly, reading small print or reading extensively cannot cause damage to the eyes. This is true even for people who already have poor vision. Although using computers will not damage your eyes, fatigue, eye strain or dry eye may occur with prolonged use. The eyes are meant to be used!
