Another thing to keep in mind is that headaches can come from a number of sources.

Caffeine withdrawal can also cause headaches to happen. To answer your question if the glasses really work, the short answer is that they do for the majority of people, but for someone who is spending a lot of time on computers, you might want to consider getting something more than just glare protection for your glasses.

You can take more frequent breaks, even 1-2 minutes extra will help. This allows your eyes to produce a little bit more tears for the day.
Keep eye drops handy. There are really good over the counter drops, we sell Retain MGD in our office and haven't had complaints yet.
There are drops specifically for Dry Eye Syndrome that you would need an actual medication for. Our biggest one we prescribe is Xiidra but Restasis also works.
Getting a pair of blue light filter lenses, even if you don't wear glasses will help relieve eye strain as well. Don't get just whatever cheap ones are available, make sure they're of the highest quality for your occupation. It's worth every penny.
