if you are seeing foggy then please see a ophthalmologist,he will have a complete examination and look for where the problem is.
halos around light is due to corneal edema
cause for corneal edema could be cataract
. the other symptom which you have about burning,is it just burning or it is some pain..cause if you also have pain then it could be pointing towards glaucoma.
please get your eyes checked as soon as possible.
hope this helps.
