L_Killkenny mentioned the same thing I would: lower powered scopes.
The first scope I put on my .22 was of the common, inexpensive 3-9x variety. It was okay, but for my purposes (plinking and hunting), the top end of the magnification were never really needed, and the image became a bit hazy at 7x or higher (probably wouldn't have been a problem with a more expensive scope).
I decided to switch to a fixed 4x scope. I liked that scope well enough, and it had better eye relief. Then one night racoons were causing problems out in the yard. I grabbed the gun and snuck around the corner of the house. When I raised the gun, the combination of darkness, close distance, and limited field of view made it difficult to get the racoons in my sights.
After that, I decided something that offered a wide field of view would be preferable for quick shots at small game and varmints. I got a 1.5-5x scope. It's actually a shotgun scope, but it's not much bigger than a .22 scope and has the same 50 parallax. Now when hunting, I keep the scope dialed low in case I need to get on a critter fast, but I like having the option to zoom in if I have the time.
I put a red dot on a .22 pistol some years later and temporarily gave thought to a red dot/hologram sight for my .22 rifle, but, aside from reducing weight, I can't think of any situation where a red dot would be better than my scope, and I can think of several where it would be worse.
