If you wear eyeglasses, I would recommend that you use one with longer eye relief. That is because such persons require a high eye point where the image will form and become clear to the user.
A binocular with short eye relief will not present clear images, and at the same time won’t zoom in distant images to satisfaction. It is, therefore, recommended that you go for one with generous eye-relief.
How much eye relief is enough?
Most of them do have one of greater than 10mm. However, this is not enough especially for people who wear glasses. I would, therefore recommend that you get one of up to 16mm at the minimum.
Most binocular have an old model rubber eyecups that are not flexible to adjust. When buying one, look for those with twistable designs. That means they can either turn up or even down with ease.

Hold it with both hands. Look at a distant object through the lens. Move the binocular tube carefully in either upward or downward direction.

In some instances, your tool might refuse to function. When such a thing happens, then you have to rectify it. The procedure is to open the eye that was closed as you close the other. Focus again on the same object and rotate the diopter ring until you get a clear focus of the object.
Open both eyes and look again through the binoculars, and at the same object. By now, it should be at least visible and clear. If you achieve this, then we would say that the binocular is now calibrated for your vision!

If you fail to sight objects after doing the set up, then you might not have done it correctly. The end result is to have a solid image through both eyes.
Can I fix it by myself?
Well, it depends with the nature of the damage. If it is about the adjustments, then you can do that on your own. On the other hand, if the damages are intensive, then you may need to take it to a qualified person. Self-repairing may cause more damages especially if you are not sure of the procedure.
