Contact lenses come in three main shapes. Each shape corrects a different vision problem.
Spherical lenses offer a single correction. Your optometrist will most likely recommend this type of lens if you suffer from myopia or hyperopia.
If you suffer from astigmatism and your near and far vision tends to be blurry, a toric lens will allow you to see all that life has to offer, no matter the distance.
Presbyopia causes you to have difficulty reading? Bifocal lenses correct presbyopia and difficulty focusing on near objects.
