Yes. For most people, there is a period of weeks when your brain is learning to “see” up-close and at a distance with the new lens. This adjustment period is usually complete within 3 to 4 months. Also, like all multifocal lenses, some people report halos or glare around lights. Again, for most people this diminishes over time. For some, it becomes less troublesome but never completely goes away. Most people report that the ability to see near and far outweighs any visual side effects associated with the lens.
