10.Eye strain is a very common problem.Whether it is from working on a computer,watching TV,driving or any number of other activities,your eyes can become tired and lose focus.(36)A With that in mind,here are 4simple tips to help prevent eye strain.

3.Adjust contrast (對比度).
Ensure there is good contrast with what you are looking at.More contrast makes edges easier to recognize so the eyes don't have to focus as much.(39)B Keep overall lighting levels at a moderate level so there is good contrast around you but glare does not become a problem.
