U have a Canon dos rebel cd, and the light meter and everything in the viewfinder is blurry, has anyone else had this problem, and how did you fix it

While looking through the viewfinder, turn the little knob at the upper-right corner of the viewfinder to adjust it.
Refer to the "Adjusting Viewfinder Clarity" subsection of the "Basic Operation" chapter of the manual (page 36 in my copy) for full details.

There's a diopter adjustment knob just to the right of the viewfinder. Turn it while looking through the viewfinder at a blank wall until the numbers in the viewfinder appear sharp. This knob allows the camera to adjust for individual eyesight.

YES IT JUST NEED TO ADJUST DIAPTOR WHEEL NEXT TO VIEWFINDER. ADJUST ACCORDING TO YOUR EYE.

Next to the viewfinder ther is a diopter adjustment so you can change the focus in the viewfinder. this is so if you need glasses the camera can be set for you. Start by focusing the camera on something, then slide to turn the diopter adjustment until it looks sharp and try not to bump it.

Can you change the diopter setting on the viewfinder to accommodate your vision? It's usually a dial or slide switch at the eyepiece.

1. The viewfinder's diopter is probably out of focus (doesn't affect Auto Focus of photos). There's a dial and a +/- symbol next to the viewfinder. Turn the dial till you can see clearly through it. Alternative reason: The glass in the viewfinder is dirty/foggy. Use camera cleaning solution (a drop) on a cotton bud to clean it.

2. Malfunction needs Canon Service Centre to take a look at.

Adjust the viewfinder diopter to suit your eyesight. The control is near the viewfinder; try adjusting it and see if the image clears up. Be careful not to poke yourself in the eye as you do this.

So the problem is that it always looks blurry?
If so, look at the little dial that is coming out of the viewfinder. It corrects the viewfinder for people with bad eyesight, kind of like built in glasses. make sure the white marks are lined up.

Use the little wheel dial with the +/- sign on it right on the viewfinder...ajust it until things are clear
