Went for an eye test today and they have recommended varifocals, so I thought I'd try and read up on it before committing.
There are a bunch of numbers that mean zip to me.
Any clues anyone ?
If I have have slight long and short sightiness I would have thought it would be +ve and -ve readings , whereas both are +ve
