Alignment modification for pencil eye shields.
Accurate alignment of pencil beam eye shields to protect the lens of the eye may be made easier by means of a simple modification of existing apparatus. This involves drilling a small hole through the centre of the shield to isolate the rayline directed to the lens and fabricating a suitable plug for this hole.
