###Human: What causes sensitive and burning eyes? ###Assistant: Hello. The symptoms which you have is usually seen in patients with dry eyes. It often presents with dryness, grittiness, irritation and burning sensation which goes down after washing the face. The best way to treat simple dry eye is to use over-the-counter lubricants, for example, Carboxymethylcellulose acetate 0.5 percent eyedrops. Also, make a conscious effort to blink more frequently. Also, give a "contact lens holiday" for a few weeks. If you cannot do without your lenses even for a few weeks, then use drops called Genteal gel (Hydroxypropyl Methylcellulose) or Systane eye drops. These two can be used over contact lenses. Hope this helps you.
