Dryness and irritation in the eyes

Lately, the weather hasn't been particularly dry, so at first I thought it was just because I was tired or not feeling well... but now, even with just a little activity, my eyes feel dry and I notice myself blinking frequently and consciously. I'm worried about it... It's not like I'm sick or anything, so I hesitate to go to an ophthalmologist... I do sleep a bit less overall, though. Is there any way to manage this? Since it's my eyes, I'm a bit cautious.
