This is a very nice glass eye washer. I had something in my eye and I never figure out what it was. Eyelash, sand, who knows. Just fill the glass with water. Lean over and place the eye washer to your eye while looking forward. Open your eye and look around. The water will rinse your eye. No pain, no fuss, and it works great. The glass is very smooth and fits perfect. Comes in a little case.
