On the subject of drops, it's worth speaking to a pharmacist about getting eye cream/gel if you find that you suffer from dry eyes.

I used to get occasional headaches, and maybe once or twice a year I'd get a minor corneal abrasion, which I assumed was from stuff getting into my eyes. After a while, I was recommended by a doctor to try an eye cream for night use, and the difference was vast. Alongside my eyes feeling much better, I was sleeping better as well, which the doctor put down to how the eyes move in the head while asleep, and my eyes scratching against my lids.

I use drops during the day when I feel the need to, and on occasion when I feel tired I'll use the eye cream. Since then, no problems with my eyes and no headaches.
