For optical purposes "distance" is 20 ft/ 6 meters or farther. If the IOL put in your eye 'nailed it' then you would not need glasses for anything further than 20 ft. However you would need glasses to read, a different set for computer use, likely another for distances like 10-15 feet TV. Thus you would rather than 2-3 different pair you would have glasses RX of Plano R&L plus 3 add in progressive/no line form. the formula for determining IOL power are not 100% exact. the general error is plus/minus 0.50 diopter. For very long, very short or very astigmatic eyes the error is larger. If you are totally unhappy it should be possible to do a cornea refractive surgery like LASIK to improve your distance vision at 20 ft or further. You would however no longer be able to see clearly from 1-6 feet as you are now and you would still have to get glasses. Most people would be very happy with the result you have had.
