Eyelashes.

[Geoff Barnes]

I was giving my eyepieces a clean recently and it occurred to me that most of the stuff I was cleaning off the lens was probably greasy deposits from my eyelashes. So I got to wondering if simply trimming ones eyelashes (on the observing eye) would help prevent such contamination.

A bit of an odd thought maybe, but do any of you trim your eyelashes? (Spectacle wearers need not reply obviously).

Neither do imagers. 😉

An alternative would be to use false eyelashes as a brush.

This post reminds me of a time long gone, when I started working for a Swedish electronics company. I noticed that the microscope eyepieces were quite dirty (in a cleanroom!), so I cleaned them with a tissue. They had black residue on them. After a moment it dawned on me that some of the ladies working there were wearing mascara. Over time cleanroom policy changed for the better. So did the quality of the devices (mostly prototypes) that were manufactured there.
