Eye Doctor Instrument: The Slit Lamp

Yesterday, I was at my eye doctor for a checkup.  I know I'd be waiting for some time so I started sketching this gentleman filling out the new patient forms.  I thought I'd start with the crossed legs then work my way up.  But not soon after, I was called in and was shown the way toward one of the exam rooms.  I took the eye chart test with prescription eye glasses on.  Good results.  20/20 vision!  

This young lady administered the first dose of eye drops to dilate my pupils and left.  She would be back minutes later for the second dose.  While waiting, I thought I'd sketch that eye instrument before me. 

"Would you mind waiting outside for a few minutes?" she asked.  I stepped out of the room, sat on a chair just outside by the hallway.  Another patient walked into the room where I exited.  

Here's the slit lamp instrument I sketched.  See the feet hanging from the bottom of the platform?
