Wearing contact lenses for more than a few hours at a time with or without a monitor in front of me tends to aggravate my eyes. So I tend to wear my glasses and still over time my eyes get bloodshot and tired after a couple hours. Upon putting the pair of Gunnar RX (prescription) on I was happy to see that they were indeed my matching prescription, and I basically needed to test these for an extended period of time to see how well they would work.
After wearing these Gunnars (RX) for several weeks now, I can confirm that they definitely work. Before, I would get bloodshot eyes and once in a while and experience discomfort. I would also wake up sometimes without fully recovered eyes – they were still slightly bloodshot, particularly on little sleep. This combined with sensitive eyes and using contacts during the day tended to make my eyes dry, itchy, and bloodshot in general most of the time. All of this is gone now. I see clearly for long periods of time with extreme comfort.
I would highly recommend Gunnars for anyone who spends considerable time on the computer and/or has sensitive eyes. It has made a huge difference for me.
