Perfect near vision slight myopia...contact lens?
If one has perfect near vision but distant vision is -1 dioptre and -1.25 in the other eye and he decides to wear contact lenses, is this practical? I mean would it affect his near vision by overcorrecting or too much focus?
Because basically I think glasses/contacts would be used driving etc. and not when reading a book or on the computer.
Think about it, a pilot with perfect near vision would be constantly loking at his instruments and reading checklists etc.
Are there any airline pilots or doctors who could advise in this case?

vision correction . . . . . . . . .
Sounds like you ( is it you ? ) are mildly myopic ( = short-sighted).
Easy to see near objects, but need the stated amounts of correction
for distance or infinity.
Full answer depends to some extent on your age. In the young ( up to early 40's) if myopia is corrected for distance, then near vision will usually fall into place without any further ado. On the other hand in those of middle -age and beyond (late 40's onwards) there is likely to be some PRESBYOPIA present. This is stiffness of the lens in the eye, and the result is that when distant vision is optimal then reading glasses are necessary to focus on small things nearby. This effect is always considerably worse in dim light. In someone who needs correction to achieve that good distant vision in the first place ( ie a myopic) then satisfactory near vision may require bifocal or varifocal glasses.
Why not book a proper eye test with an optician ?

Yes Amland PPL is right.
My myopia requires a right eye correction of -1.25. My left eye previously required -0.5, but now, apparently due to age, the short sightedness is gradually reducing and the opthalmologist said, will probably end up being long sighted.
When I wear contact lenses, I wear the -1.25 in the right eye and nothing in the left. It sounds a bit weird and initially takes getting used to because the brain has to learn how to 'concentrate' on the messages being received from each eye for short or long distance work.
Glasses? - varifocals for me.
