Is it possible to blind a fly with a laser pointer?

If I aim a 5mw red laser pointer at a fly every time it lands will it damage the fly's vision?  Does the color of  laser matter?

I believe so.

House flies, as you may know, have compound eyes; eyes composed of smaller units called ommatidia.  Each unit works very much like vertebrate eyes, focusing light onto the retina, only there are many of them forming a single image.  As lasers are a concentrated beam of ~~excited~~ photons, the lens of the eye (or eyes in this case) will focus the light onto a very small area on the retina, causing localized burning and tissue damage.

Hopefully this helped.
