That's a good question and there is an ongoing discussion and it's important to decide.
With multifocal lenses, the key benefit is allowing the patient to see both far and near through the same eye.
In other words, with the same eye, you can see far and if you bring your handphone up close, you can see near as well, so that's the key advantage to the multifocal lens.
There are two disadvantages of a multifocal lens.
First is the cost, they are about 3-4 times more costly.
Secondly, most multifocal lenses have a low design and that causes a lot of glares, halos and effect. For most patients, they don't make much difference, but some patients who drive a lot or are fussy about nice vision find it intolerable.
It is not for everyone, generally speaking, your doctor should be telling you about all these side effects.
