LensShopper - Contact lens price comparison
Yes you can! There are two ways of solving this problem, the first is that one uses progressive or bi-focal lenses, these are lenses with the optical features for tackling both longsightedness and shortsightedness within the same lenses.
The other solution is to used standard lenses but to change the lenses from context to context using lenses for shortsightedness when appropriate and changing to lenses for longsightedness when felt appropriate. Which of these possible solutions are most appropriate for an individual user is difficult to say here save to suggest yet again that any decision by the wearer should be made in consultation with an optician.
