Improper microscope usage increases myopia

I have almost 20-20 vision. Not anymore.

The regular usage of microscope increased my chance to acquire myopia/astigmatism/etc.

Few things to keep in mind when using microscope, if you need to slow down getting myopia.
  1. Make sure light intensity is not too bright. The last user could have tweaked the intensity to max.
  2. Adjust the ocular lens (in binocular microscope) so that both your eyes are comfortable. Previous user could have adjusted the focus of one of the ocular lens to fit his/her left or right eye. If that happens, you will strain one of your eyes (from the differing focal point of these ocular lenses) due to long usage.
  3. Try to avoid looking at laser or excitation light too often. Open lasers are risky as it can severely damage your retina. Don't wear jewellery that can diffract the laser (e.g. diamond ring).
  4. Try to rest in between work by looking out the window and focus on distant objects.
