Medical reviewer [Mr Mohamed Mohyudin](https://eyehealthguide.org/reviewers/mohamed-mohyudin/)· Last recorded site review July 6, 2026 ### About this review This page inherits the site’s previous review record. A separate, current article sign-off has not yet been recorded. [How review works](https://eyehealthguide.org/reviewers/) · [Official biography & credentials](https://mohamedmohyudin.co.uk/author/mohamed-mohyudin/) Quick answer A monofocal cataract lens gives one main clear focus — usually distance — so reading glasses are still typical. Multifocal and trifocal lenses split light to cover more distances and may reduce glasses use, often with a higher chance of halos or glare at night. Eye Health Guide also groups EDOF lenses as a middle path for many people, and toric versions of these designs when regular astigmatism needs correcting. No option guarantees spectacle independence; suitability depends on eye health and your tolerance for trade-offs. ### On this page ⌄ 1. Monofocal lenses: the usual baseline 2.

They provide a single planned focus, most often set for clear distance vision. Near and intermediate tasks then rely on reading glasses, progressive spectacles or a monovision strategy if that is agreed. Image quality and contrast are often excellent when the eye is otherwise healthy, which is one reason monofocals remain the NHS standard in many pathways. ## Multifocal and trifocal lenses: wider range, different optics Multifocal and trifocal designs use zones or diffraction patterns so the brain can use more than one focus. The aim is clearer intermediate and near vision with less dependence on glasses. The optical trade-off for some people is rings, halos or glare around lights, especially when driving at night. Not every cornea, macula or personality suits that compromise. Your surgeon may advise against multifocals if the retina, tear film or cornea is unlikely to support crisp shared foci. ## Where EDOF and toric designs fit Extended-depth-of-focus (EDOF) lenses stretch the clear range, often helping screens and dashboard distances, usually with less near power than a full trifocal for many users. Toric versions of monofocal, EDOF or multifocal lenses add correction for regular corneal astigmatism. Mixing ideas — for example a monofocal in one eye and a different design in the other — is sometimes planned, but it needs a clear rationale. Online comparisons cannot decide this for your eyes. ## Night driving and glare: the honest trade-off If you drive a lot after dark, ask specifically about photic phenomena — halos, starbursts and glare. These are discussed more often with multifocal optics than with standard monofocals. Some people adapt over weeks; others remain sensitive and prefer glasses or a different strategy. Contrast sensitivity can also feel different. Bring real examples from your life — motorways, rain, shift work — so counselling stays practical rather than abstract. ## Who may be a poorer fit for multifocals Significant macular disease, irregular astigmatism, uncontrolled dry eye, certain corneal scars and unrealistic expectations all raise caution. Previous laser eye surgery does not automatically rule options out, but it complicates power calculation and counselling. Glaucoma and other optic-nerve problems may also change the advice. Your examination, not a leaflet, decides candidacy. ## Choosing without hype Frame the decision as priorities, not products. If maximum distance sharpness and simple night vision matter most, a monofocal (with or without toric correction) is often enough. If reducing readers matters more and your eyes qualify, multifocal, trifocal or EDOF designs enter the conversation — still without a guarantee of glasses-free living. In the UK, check what your NHS service offers locally and what private pathways add, including costs and follow-up if you are unhappy with night symptoms. ## Read next ## Frequently asked questions ### What is the difference between monofocal and multifocal lenses? A monofocal lens has one main focus, usually distance, so near glasses are common afterwards. A multifocal lens provides more than one focus to reduce glasses across distances, often with a greater chance of night halos or glare. Neither is universally better; they suit different priorities. ### Are trifocal lenses better than bifocal multifocals? Trifocals are designed to include a stronger intermediate range as well as distance and near. "Better" depends on your tasks and how you tolerate the optical side effects. Your surgeon will explain which design, if any, fits your eyes. ### Is an EDOF lens a multifocal? EDOF lenses are related but not the same as traditional multifocals. They extend depth of focus, often helping intermediate vision, with a near-range and side-effect profile that differs by design. Ask how the specific lens under discussion behaves for reading and night driving. ### Which lens is better for night driving? Many people find standard monofocal lenses more predictable for night comfort. Multifocal optics are more often linked with halos or glare, though experiences vary. If night driving is essential, say so before you choose. ### Can I have a multifocal lens on the NHS? Multifocal lenses are not routinely available on every NHS cataract pathway. Local rules differ. Ask what is offered where you are treated and whether a private upgrade pathway exists. ### What about monofocal versus monovision? Monovision uses monofocal (or similar) targets set differently in each eye — one more for distance, one more for near. It is a strategy, not a separate branded lens family. Adaptation varies; some people try the idea with contact lenses first when appropriate. ### Do multifocal lenses cause blurry vision? Some people notice a learning period or softer contrast while the brain adapts to shared foci. Persistent blur needs a check for residual prescription, dry eye or other eye disease. Report ongoing problems rather than waiting them out indefinitely. ### Should I choose the lens with the most freedom from glasses? Not automatically. The widest advertised range can bring the largest optical trade-offs. Match the lens to your eyes and the tasks you value, and remember spectacle independence is never guaranteed. Your next step ## Take this to your appointment Write down what has changed, when it started, your current medicines and the questions you want answered. Take these to your eye-care appointment. Sudden loss of sight, severe eye pain or a dark curtain across vision needs immediate assessment.
