Yes; don't touch the case, and don't expose it to UV light (sunlight) - after all when kept in the retail packaging, away from your skin oils, daily dirt and under artificial light in a shop stand, these things stay clear for years
As neither of these are very practical considering the fact that it's a phone case, I recommend you throw it away (or give it to someone who doesn't care that it is yellowed, if you're concerned about the environmental impact of frivolously throwing plastic away) and buy another one
When buying a replacement consider one that is not clear plastic, such as one that has coloured or black plastic, or one that is a different kind of clear plastic - harder plastics seem to resist yellowing better
I am not a chemist, but information I read on the internet in the past kind of answers your problem.
It is the composition of the material which is not "stable" enough and some of its components react with gases in the air (probably oxygen). Although that reaction is very slow, it is unstoppable. In time, the "plastic" will degrade at least color, maybe other properties as well.
