If I understand your Query correctly you need to wear reading glasses. Correct? The EOS Canon cameras have a pretty extensive range of adjustability built in. If you need something additional (rather unlikely) then match the diopeter number to the number you wear with your reading glasses. Such as +1.5 or +2.5...I purchased this adjustment lenses but actually found out the Canon had the correct adjustment on the camera for me around +1.75. So I don't use this piece.

Contact Splaqua. I have a smaller deviation in my correction , and in this situation it is suggested to go with the lower number. I know that Splaqua, and probably others, will help with getting the proper correction for each eye in circumstances that call for it.

Yes, I think the right-hand diopter adjustment is usual. I admit I don't use it often as the improved adjustable eyecups and big bright eyepieces allow me to keep my glasses on. I do like these binoculars. I especially value their ability to focus close-up, so they work as well for the backyard feeder as out in the field.

Well it really depends on what type of area you live in and what you are looking at. If you are in a light polluted city or are trying to see fainter objects then a dobsonian would help. If you want to look at fairly bright objects like planets, moon and terrestrial things then a refractor will be great for that.

with out the 3x magnifier I wanted the two dot easy to see . with out the 3x magnifier over two dots hard to see them . yeah with 4 dots and no &#9726;3x magnifier looks like a straight line. I dint want the weight and pay the extra cash. my friend has the 4 dot and 3x magnifier really nice set up. hope this helped you :)

Having using both with glasses, I would chose the compact. It is rectangular rather than square like the original. Thus you don't have to turn head much to take a look.

I also see an oblong dot, almost a set of dots that seem not round. I was diagnosed a few years back with a "mild astigmatism", and although I do have glasses, I generally do not wear them. I was unsure if it was the astigmatism or a faulty unit, so spoke with Trijicon on the phone and they said to exchange the unit with a new one. I did so through Amazon and found that the new unit did the exact same thing. I believe that its the astigmatism, and although mine is so mild that I don't have the need to wear glasses, it still makes the laser dot seem oblong.

The lens reflector in the ophthalmoloscope might be bent downwards. Try sticking in a toothpick and jiggling it around. It's quite irritating actually. You might want to contact the vendor for a replacement if all else fails.

When you pull the eye viewfinder, you have a small wheel on the left side. Just spin it until it looks crisp. Same method as binoculars.

Make sure the current sight is graduated at the correct distance. It should be fine.

Kevin, I use my glasses with one of my Tasco scopes. Most of the other ones seem to focus just fine without using my glasses.

Nancy - Regarding using these for driving: While you may be able to dial in your correct number (in diopters, assuming it's -6 or less) the peripheral vision is limited. For this reason, if using for driving, you'd need to turn your head rather than your eyes, to see thing not directly in front of you. This is most likely the reason they're not recommended for driving. A safety risk . . . Hope this helps!

Practice in the day time on something far away like a street sign or building or something. Use the widest lens first. Dont use the extra magnifer. Put the lens in all the way and tighten the screw. Use the finder scope on the top to get it close to the object you want to see. Then adjust the focus dial raising and lowering the lens untill you can see an image. I used mine in the day time several times before I tried it succesfully at night.

You don't have to look thru magnifier to use light. You can also just look thru magnifier with light off. The light is directional. Point it where you want light. Light has an on/off switch.

I did that with my prescription sunglasses. I'm near-sighted & have sunglasses that I use for driving, but I couldn't see the dashboard instruments. I put these on my sunglasses so that I can delay ordering new glasses for another year or two. :) Works really well.

As one of the other responders answered, you can use the magnifier with or without your glasses. The different levels of magnification and the light it has makes this a very useful tool. I gave some of these for Christmas gifts and all are being used on a regular basis.

I use eyeglasses but find that I can adjust each eye for perfect glasses free viewing. My eyesight is really bad but I have absolutely now problem using these binoculars.
