I've noticed that my eyesight isn't as good as it used to be. Is it normal to lose your vision as you age?

Yes, it is normal for your eyesight to gradually deteriorate with age. It's a natural part of the aging process and can happen to everyone. Your eyesight may become less sharp, especially if you are nearsighted or farsighted. You may also have trouble seeing in dim light or at night.
