This video shows a pyogenic granuloma that has formed on the inner eyelid. This formed over a prior chalazion, which you can also see in the video.

Here you can see a pyogenic granuloma that has formed on the inner surface of the lower eyelid. Despite the name, these growths are neither “pyogenic” nor are they truly “granuloma.” To see how this one looks in motion, you should watch our pyogenic video from which this photo was taken.

Here you can see a pyogenic granuloma that has formed on the inner eyelid. These are common and often occur at the site of a chalazion or prior sutures from conjunctiva or eyelid surgery. To get a better idea of how mobile this mass is, you may want to watch our pyogenic granuloma video from which this was captured.

This video shows an animatronic eye, designed as a type of art exhibit. The prostetic is tied into a face tracker. Interesting how we are riveted by the presence of an eye … such that we notice eyes pointed at us, even out of the corner of our vision from across a room.

This video shows the use of a lensometer, a device used to check the prescription in glasses. This device can be tricky for the novice technician to use, as you must align the glasses well and move two dials at the same time to hone in on the prescription.

Here are the steps:

1. Place glasses on platform and secure
2. Turn axis and focus nobs so that the SMALL lines are straight and focused
Write down the number. This is your sphere.
3. Turn the focus nob until the fat lines become focused, and look at the new number on the focus nob. The DIFFERENCE from your prior sphere value is the CYLINDER value. If you changed from +1.00 to +4.00, then your cylinder is +3.00. If you changed from +1.00 to -1.50, then your cylinder is -2.50. In other words, the cylinder can be a positive or negative number, depending upon the direction you have to turn the focus nob.
4. Check the degrees on the axis dial. This is your cylinder axis.

If you want to check the bifocal add:

5. Move the glasses so that the bifocal segment is being read.
6. Turn the focus nob again until the fat lines again become focussed.
The amount of change needed to refocus the fat lines will give you your bifocal power.

This photo shows the lines you see when looking through a lensometer. When you get the three smaller lines oriented correctly and focused (like in this photograph) then you have your sphere.

You may want to watch our video on lensometry to see how this looks in real life.

This photo shows the focus dial on a lensometer. To determine the sphere, you need to move both the focus and axis dials so that the three small lines are straight and clear.

For a better idea how this looks, watch our lensometer video, from which this snapshot was taken.
