Ever find yourself leaning in close to your monitor to check out how something looks in a design, to see if that’s a dot or a comma you’ve used in your code, or just to get a closer look at the details of what you’re working on? It’s something I do all the time, and it very well could be part of the reason my eyes are so bad, and keep getting worse.

To save yourself the trouble of leaning forward and squinting, there’s an option you can turn on in OSX’s Universal Access section of System Preferences to help out, and just make what you’re looking at bigger. Just enable “Zoom”, and you can use a set of keyboard shortcuts to zoom in on whatever your cursor is currently pointing at.

There are shortcuts for zooming in, zooming out, and if you like, once you’ve zoomed in, you can keep hitting the shortcut to zoom in until your cursor is too big for the screen. While this isn’t exactly the most earth-shattering bit of information, it’s still something that I’ve found useful, and thought I share for those who haven’t seen it yet.
