blinking: some people just blink a lot. could be dryness or allergies, but it sounds more like a nervous habit or tick to me... mild neurological thing. not much info i can give you other than try using over-the-counter artificial tears/lubricant eyedrops and see if that takes the burning away and makes you blink less...
pressure on your eyes/forehad: dont know. thats an interesting complaint. you could have some sort of refractive error...only an eye exam would be diagnostic in that case. "seeing fine" does not mean tnhat you have or dont have a refractive error. lots of people who need glasses/contacts VERY BADLY can "see fine" at all distances. like my 15 year old son. he "sees" 20/20 at ALL DISTANCES, but trust me he needs contacts b/c he is significantly farsighted. dont assume that just b/c you see clearly that you dont need glasses or contacts. you might. only an eye exam could tell you for sure...
same with the pressure feeling and the "windsheild being too close"...you probably need an eye exam to have someone figure this stuff out...
