Sometimes it's hard to tell what's gong on while one is alarmed at the symptoms.
aware of a slight sensation in my eyes
Can you elaborate on that.
Who are you going to see? I don't thing an eye test will be much use in its basic form. If you are simply going to an optician make sure it's one that does the retinal photography - that's quite good science, and will be of use to an eye surgeon if you eventually go to one.
