Actually, reading from a computer screen (or book for that matter) for extended periods of time is not good for your eyes. Your eyes are only focused at a specific distance for lengthy periods which makes it so that your focusing muscles are overworked and "locked" in that position. That's why you develop eye strain, which itself isn't bad for your eyes (Except for the fact that every time you blink it feels like someone is stabbing you in the eye, although I might be slightly over exaggerating it does hurt a lot. I've experienced it before). But I'm sure that over time it will damage your eyes. That is what my optometrist told me anyways.

To counter this effect he told me to focus on distance objects every now and then so that your muscles are constantly being used.

Yes, eye strain can be an issue, but that's not something which is exclusive to people who use computers which is my main point - reading a textbook online is no worse than reading a textbook on print, and neither can actually harm your eyes. (By harm I mean permanent damage... discomfort is a seperate issue).

The myth that using a computer for prolonged periods of time will harm your eyes is just that - a myth.

Ah I see what you mean. That's why I also added reading a book in parenthesis. But yeah, they both have the same effect. It's just ridiculous to think that the electromagnetic waves emitted by a computer screen could damage your eyes. They aren't nearly as powerful enough to do so.

If textbook cost is the major limiting factor (but you don't mind carrying around a textbook) you should consider borrowing your textbook from a campus library if it's available.

I've had a bunch of courses over the past few years where I've borrowed the text at the beginning of the year, renewed it online as needed, and just returned it at the end. It was awesome.

A lot of profs have been getting students to find articles online instead of buying courseware, which I love. My prof last term saved each student from paying $200 for courseware!

As for textbooks, I don't know. I don't usually buy those. When I do, I never read them. They are a waste to me either way. (This completely depends on your program and your course though)

Hey Alborz, how's it going? (This is Mike, last term's Math 2A03 TA)

I think this is the bottom line...think of how much money you're spending on university. If it comes down to the choice of shelling out a little extra cash (not that much compared with your whole tuition cost), I definitely think it's worth it if it translates into better acquisition of knowledge. It's $50, $100, even $200 well spent, since it's the whole reason you're here.


See if someone preferred studying from a computer screen it changes things...but given that you need a book in front of you, that should be the bottom line. If you're really desperate and in a dire financial situation, keep in mind that most course texts are put on reserve at an appropriate library (Thode for science, Mills for humanities, etc.) by your prof. You can always go out of your way to study at the library which can be a good way for you to focus without spending a fortune on the text.

Hope that helps!

Whether or not there's a paper in existence that specifically says "Computer monitors do not harm your eyes" I don't know since I'm not exactly up on my medical journals anymore. But I do know that there's an entire area of ergonomics devoted just to computer workstations and it's recommended that you stop working every hour or so to avoid musculo-skeletal problems (like repetitive strain injuries, back and neck pain, etc).

Though this problem may very well exist when reading a book, it's far easier to put yourself in an uncomfortable (hence ergonomically incorrect) position while using a computer than reading a book since you can move a book around wherever you want.

Of all the courses I've had at Mac (that's 4 years worth of courses by now), only two courses have had textbooks at the library and one course with a prof who had us find articles online. I'm not sure what program you're in, but for me (Social Sciences), it's pretty unlikely to find the textbooks anywhere other than the bookstore.

And the prices are different with everyone too. If I bought every single required book for every single class, I would easily spend $500 per semester at least. $1000 a year for books is too much in my opinion, especially when my tuition is $5500. My boyfriend is in Engineering and he spends at least $700 per semester.
