Different optical categories
Eyhance changes the central power profile of an enhanced monofocal to extend depth modestly. Vivity uses non-diffractive wavefront shaping to create a longer focal range.
That distinction matters more than the brand comparison. The expected range, tolerance of residual error and counselling about near tasks are not identical.
Distance and intermediate tasks
Both designs are intended to preserve useful distance vision in suitable eyes. Eyhance may help with arm's-length tasks such as a dashboard or some computer work compared with a basic monofocal.
Vivity is intended to provide a broader intermediate range and may support more functional near activities, but the smallest print or prolonged reading often still needs correction.
Halos, glare and contrast
Neither is a traditional trifocal, and both are often considered when a patient wants more range without choosing a multifocal light-splitting design. That does not mean zero halos, glare or contrast complaints.
Dry eye, residual astigmatism, posterior-capsule change, pupil conditions and retinal disease can influence symptoms. Individual risk cannot be predicted from the product name alone.
Toric options and measurement quality
Eyhance Toric II and Vivity Toric variants may be options for regular corneal astigmatism. The decision requires repeatable keratometry or tomography and accurate biometry.
A toric model corrects cylinder but does not change the basic near-range limitations of the underlying optic. Rotation away from the planned axis can reduce astigmatic correction.
Who may prefer each approach?
Eyhance may suit a patient who prioritises a monofocal-style strategy and accepts reading glasses for closer work. Vivity may suit a patient seeking more intermediate range and willing to discuss the additional optical trade-offs and cost.
Macular OCT, optic-nerve status, corneal regularity and daily tasks decide more than age alone. A blended target between the two eyes can also change functional range and depth perception.
Useful questions for your consultation

- Is a blended target appropriate?
- Do I need toric correction?
- What makes one design safer for my macula and cornea?
Frequently asked questions
Which is better for reading?
Vivity may provide more functional near range, but neither is designed to guarantee small-print reading without glasses.
Which has fewer halos?
Both aim for a lower disturbance profile than traditional multifocal strategies, but symptoms still vary by eye and residual prescription.
Can both correct astigmatism?
Toric variants exist, subject to suitable regular astigmatism and local availability.
Is Eyhance a premium lens?
It is commonly called an enhanced monofocal. Pricing labels do not change its optical category.
