If you've ever shopped for sports sunglasses for running, cycling, hiking, or whatever else, you know there are tons of different coloured lenses to choose from. From copper to rose to yellow, these do make a little bit of a difference in what you see. The Wirecutter digs into when and why this might matter.

Gunnar Optiks and Uvex computer glasses both promise to reduce eye strain, prevent computer-related headaches, and be comfortable to wear for long periods of time. But Uvex's basic frames, while not even remotely as visually appealing as the Gunnar line, are a fraction of the cost. Let's see who is victorious in this battle between beauty and the beast.

Keeping my glasses from slipping down my face is a constant battle. It's a classic nerd trope that holds true, for me, and I've been losing the fight against gravity. But I've found some help in the form of Nerdwax.

Whether you're on your first pair of glasses or your tenth, you may still be put off by phrases like "temple arms" and "lens height," especially if you're interested in shopping for your own frames. This visual guide shows you what all those terms mean so you can buy confidently.

When it comes to entertaining, I really embrace the whole "the more the merrier" thing, but that philosophy does not extend to dishes. To cut down on the amount of sudsy labour I'll have to do after guests leave, I'll be using The Kitchn's "one person = one drinking vessel" rule.

If your glasses need serious adjustment, take them to a professional, but there's a lot you can do to make yours more comfortable at home.

Last month, we put Riedel's fancy $39.95 Coke glass through its paces in a series of Coca-Cola "taste-offs". To our surprise, it really did improve the carbonation and overall flavour of the drink; especially when compared to an aluminium can. However, there was one receptacle that we didn't get a chance to test -- the iconic glass Coke bottle (AKA the best way to drink Coke.) Prepare for the ultimate face-off!

Dear Lifehacker, I have a really old pair of beaten-up glasses. While my prescription hasn't changed, the glasses are scratched, ill-fitting and just plain ugly. I can't afford to go out and buy a new pair, so I'm wondering if it's possible to fix these ones up to make them last a bit longer?

If you're caught without your reading glasses, or you encounter some terrifically fine print somewhere, you have two options: curse your abnormal retina design or pinch your fingers together. The latter is like adjusting the f-stop on your eyeballs.

When our eyeglasses are smudged, we reach for the corner of our shirt to clean them. You probably know that is the wrong way to clean glasses, but you do it anyway. According to a report by the Wall Street Journal, you just need soap and a cotton cloth to clean glasses the right way.

Instead of constantly pushing your glasses back onto your face like a 90s movie nerd, weblog Tested recommends wrapping the ends in a bit of heat shrink to keep them from slipping.
