OK, so playing your iPod (etc) too loud damaged your hearing, slouching in front of your destop did your back in, while mice and keyboards have given you RSI. Now you can worry about your eyesight. A Wall Street Journal/AP story in The Baltimore Sun says:
As use of portable hand-held gadgets soars, Americans are becoming a nation of squinters who spend hours hunched over gadgets such as PDAs, cell phones, game devices and iPods, straining to read small text everywhere from dimly lighted restaurants to sunny park benches. With mobile technology growing increasingly sophisticated -- allowing people to surf the Web, build PowerPoint presentations and watch "The Daily Show" on screens barely larger than a postage stamp -- many users say they are experiencing eyestrain.
For decades, optometrists have recognized that spending long hours in front of a desktop computer can lead to a range of eye-related problems, including headaches, burning sensations and temporarily blurred vision. Now, hand-helds are triggering a fresh round of complaints. Many of the factors known to cause eyestrain on larger computers -- such as low-contrast screens and fonts smaller than 11 points -- are especially common on mobile devices. Moreover, to conserve battery life, hand-helds usually have dimmer displays than do desktop computers.
