7.Type: Multifocal
This lens splits light into a distance image and a near image that you see at the same time. The upside is that you shouldn’t need glasses afterward. But it can cause glare or a halo effect, which can sometimes make it harder to see, especially at night.
8.Type: Toric
If you have astigmatism, your vision is blurred because your cornea is shaped less like a basketball (as it should be) and more like a football. That affects the way light focuses inside your eye. Scientists designed the toric lens to compensate for the football shape of the astigmatism eye and provide clearer vision, even without glasses.
