Distance (D), intermediate (I) and near (N) focal points of multifocal IOLs have an energy distribution pattern that explains the appearance of a halo. The size of the halo corresponds to the add ...

Immediately postop, patients with multifocal IOLs may be conscious of halos around distant light sources. After cortical adaptation, most patients find the halos much less noticeable. (Images ...

Multifocal replacement lenses are more likely to cause halos and glare than monofocal ones. But they also help you see both near and distant objects. Discuss the type of lens you need before the ...

However, they may want to consider and weigh up the potential side effects of multifocal lenses, such as perceiving halos and glare, which could affect activities like driving at night.

Scientists have developed a new technique that significantly reduces the halo effect that is generated when using multifocal (contact and intra-ocular) lenses and looking at bright point sources ...

Extended depth of focus (EDOF) lenses provide an innovative middle ground between monofocal and multifocal options ... while minimizing the glare and halos of some other premium lenses.
