What Causes Pressure In Eyes And Light Sensitivity?

Hi, I was diagnosed with herpes 3 years ago, and am having some eye pain. It feels like there s pressure in my eyes, sometimes it feels like there s sand in my eyes, it seems harder to focus then normal, I m accumulating more sleep in my eyes then normal, and my eyes are sensative to light. I don t have health insurance, and was wondering if there was anything I could do to help the situation. I was also wondering what the chances were that there would be permanent damage, or that nothing would happen. Thanks.
