Had to review this after downloading that recommended "Tomato Clock" extension by FF.

Using this eyeCare extension for more than a year now, far more useful than Tomato clock, and more customizable.

I do wish it allowed you to select a custom sound to play from your HDD, but it still has nice variations to warn you with.

Maybe add a volume control for the sound played? That could be useful.

In the end, this helped me deal with my dry eyes issue. It tells me when to take a break 20/20/20 rule and all, as recommended by my eye doc. Now I have set it to 30 mins, much better.

Simple app that works well. I like that you can tweak it and there's a quick disable button so I can stop it while streaming video. Didn't realise how much it helped until I forgot to re-enable it one day!

it's very good for my eyes :D

Essential app for keeping yourself from becoming near-sighted.

Very innovative extension! very useful!! great work!

Very useful extension. Reminds me in multiple ways to take breaks and do eye exercises. Very flexible.
