I have a pair of 8 x 21 Tacso binocluars. Is there any way that I can make it have some sort of night vision? When I say that I dont mean James Bond spy stuff. I mean ANYTHING that I can to do to make it see ANY better when it is dark.
-Preferably CHEAP!!
Here are the binocular's specs:
Model : 165BCR
Magnification: 8x
Field of View: 383ft/126m
Exit-Pupil: 2.6mm
Prism Type: Roof
Weight: 6.5 oz
Objective lens Diameter: 21mm
Lens Coating: Fully Coated
Focus Type: Center
Features: Rubber fold-down eyecups, camo rubber armor, carrying pouch and neck strap
Name: Tasco Essentials 8x21 165BCR Folding Roof Prism FRP Compact Camo Binoculars
----------------------------------
Thanks for the help.

Tasco bino's are cheap. Even replacing these with a high quality pair at the same size would increase the amount of light transmitted to your eye, and therefore your ability to see at dusk. As a hunter, the rule is "you can't shoot what you can't see." Optics are KEY. High quality binoculars are expensive. The lenses are perfect and the coatings are important for reducing scatter of light between the lens elements. A good pair of binoculars will cost up to $1500 without any night vision gadgetry.
Night vision is a completely different technology. You won't be reinventing it cheaply. In addition to a series of light concentrating lenses, there is an electronic system that picks up low level light and displays it as a phosphorescent image. A good source of information if you want to learn about how things like that are made is:

Except for attaching a light to it so you can illuminate whatever you're looking at, there probably isn't any way for an amateur to significantly increase night vision ability on binoculars.
EDIT: The only other way that would be remotely possible would be if you could use a sort of 'night glass' system, refracting the light first one way and then the other to make the image smaller (this gets more light in the same area of your eye and makes it easier to see). However, this would be quite difficult to do and may not be very effective.

No...
Save your nickels and buy a pair. BTW, the wider the aperture (is that the the right word there?) the better it will do in low light conditions. For instance, an 8x55 pair will do a lot better than your pair at dusk or dawn.

Night vision does not work with optics, but light amplification. Electronic sensors detect existing light, however faint, and amplifies it to the visible light spectrum.

What you do is.. buy a set of night vision binoculars.

Use them during the day and pretend it's night time.

Use them in a well lit area.
