I do agree, the problem is repairers do not get a technical manual from manufacturer and there is no apparent tuning screw, when you have to take away (and probably destroy) the whole rubber coating to discover the screws location, it is a very rough way to proceed, any other ideas ? Thanks

How do I collimate my binoculars please because they have double vision.


It'll depend a bit on the root of the problem.
You can get double vision from properly aligned binoculars if the optics are too far apart or too close, relative to the spacing of your eyes. you'll need to bend them at the central hinge to make sure that both eyes are centered on the input lenses.

If you're still getting the migraine-inducing double image, they probably got dropped at some point. This can be a wide range of difficulty to fix. Here's what I've done in some past cases with flea market binocs that I bought cheap due to the skewed alignment.

For many binocs, the upper (eyeball end) and/or lower (field end) are screwed to the central body of the binocs, where all the folding optics are to widen the lenses from your eye spacing. If they have been dropped, (or disassembled and put back together sloppy), then they may be cockeyed at one of these joins. Look at each seam to the central body and see if any of them have a gap, especially one that is larger on one side than another. You can then apply firm un-screwing twist and see if it will unscrew. if it will, and before you unscrew it all the way, wash your hands and clear a clean surface to work on. Unscrew the segment, inspect the threads for crud that might have got in while cockeyed. Then visually square up the component and gently screw it back in. if it was mis-assembled, the threads may be a bit gummed, and you'll have to be patient to keep the optic square, and back off and start again if it tries to drag over to cockeyed threading. Once it's square, gently working the thread back into place by turning back and forth a half turn back, 3/4 forward, half back, 3/4 forward, can help the thread recuperate. Eventually, it should screw all the way in, firmly, and be square. No more double vision.

For some models, like my Nikon fixed pocket binocs, there's no zoom and just a focus knob. On my brothers pair, it got cockeyed. In that case, I gently unscrewed the locking rings for the glass on the eyeball side. One of them was loose and the lens was a bit cockeyed. In that case, I removed, it (wearing nitrile gloves), cleaned it with eyeglasses cleaning solution and a microfiber cloth, put it back in, screwed the ring in firmly,and it was good to go.

Bottom line, if you have some basic DIY skills, unscrewing the entry optics, or the optics sections, isn't too big a deal. Just be mindful not to let dust (or worse) get inside while you have things open. You can get a lot of fix just from that much.

Good Luck!

This problem is caused by a bad optical block. Sony has extended the warranty on this and several other models through December 2008 so you must act SOON. A link to the problem and instructions on how to obtain service can be found here:

My grandson dropped the binoculars and now I see double. How can I fix this? These worked great until this happened. I see the screws on either side of the eyepieces but don't know if I am supposed to use...


Hello. When the binocs were dropped one of the lenses popped out of it's retaining frame. If this is an old set you can open it up and see what you can do. However, my recommendation is to call Tasco Customer Service at: (800) 423-3537. Opening it up will void any warranty and introduce dust into the interior which will appear and annoy you. Joe

Mis-alignement between eyepieces


Up close to the eyepieces around the barrels are small screws that you can use to "collaminate" your binocs. The screws aren't meant to be accessed by the owner and most manufacturers cover them up with the material that surrounds the binocs. Of course the binocs in their current state are useless anyhow, so I wouldn't hesitate to peel up the material to look for the screws. If you do it carefully, you can reseat the material anyhow. Then once you locate the small screws, put the binocs on a stand or a table outside. Focus on something far away using one eye. Then using both eyes, you adjust the screw on the other eyepiece while looking through the binocs. Adjust until you get a single image. You can use loctite, or nail polish to "glue" the screw in the final position if it is really loose.

When the colors do not align properly you need to clean the LED printheads. Full instructions on how to do this are located at:
