Eye Strain due to over use or extended use of Night Vision and Thermal optics. How do you avoid this. I spent 2 nights, about 4-5 hrs both nights at the rabbit wars. I didn't have a monocular, (will next time). The night starts well enough but by the end of each night I was suffering and having trouble seeing well at all. The sight picture looked like it was fogging up but I'm sure it was my eye.. I'm guessing turning down the brightness and/or the contrast will help. And using the monocular to scan will help as well. Its a Pard SA45LRF scope. Anyone got some hints for me.
Yep. Use a Binocular type device. Most of these use only one AMOLED between both eyepieces. The best are obviously ones we provide

They have two AMOLED screens rather than one shared between both eyes. Either way you still use BOTH eyes and this stops the problem. The main thing is that your eyes do not see. Oh boy I can already see the response to that. The eyes are only lenses that direct light rays to the sensors at the back of the eye and the signal is sent to the brain which does the seeing. Make sense ?? Does not matter anyway. The brain is set naturally to use the signal from two eyes. Use of only one eye creates strain after a long session.
Problem here......... they are expensive, but you did ask.
PS. Yes turning down the gain and especially the brightness will help considerably.
As a contractor I always use a Bino type.
