Vortex Viper PST riflescopes use a fast focus eyepiece designed
to quickly and easily
adjust the focus on the
riflescope’s reticle.
Once this adjustment is complete, it will not be necessary
to re-focus every time you use the riflescope. However,
because your eyesight may change over time, you should
re-check this adjustment periodically.
1. Look through the
riflescope at a blank white
wall or up at the sky.
2. Turn the eyepiece focus
knob in or out until the reticle image is as crisp as possible.
Note: Try to make this particular adjustment quickly, as the eye
will try to compensate for an out-of-focus reticle.

Looking directly at the sun through a rifl escope, or any optical
instrument, can cause severe and permanent damage to your eyesight.
