Spectacle options run from single-vision readers through flat-top bifocals to progressive addition lenses; contact lens options divide into monovision (one eye corrected for distance, the dominant one, the other for near) and simultaneous-vision or translating multifocals; surgical options include monovision corneal correction, multifocal intraocular lenses and, for early presbyopes, corneal inlays. The addition itself follows demand minus half the amplitude of accommodation, cross-checked with the age scaffold: about +1.00 to +1.25 D in the mid-forties, +1.50 to +1.75 D at fifty, and +2.50 to +3.00 D by sixty and beyond. ## What you must remember - **Physiology:** lens stiffening and geometric changes reduce amplitude roughly 0.25-0.30 D per year; symptoms begin when the receding near point threatens the habitual working distance, classically at 40-45 years. - **Addition by age:** mid-40s +1.00 to +1.25; around 50 years +1.50 to +1.75; around 55 +2.00; 60 and beyond +2.50 to +3.00 — a starting scaffold always refined at the patient's measured working distance. - **Addition formula:** add = dioptric demand − half the amplitude of accommodation; never spend the full amplitude or asthenopia follows. - **Spectacle menu:** single-vision near glasses (cheap, wide field, blurred distance), bifocals (jump, visible line), progressives (all distances, peripheral aberration), occupational or "computer" lenses with intermediate bias. - **Contact lens routes:** monovision — dominant eye distance, fellow eye near, typically with a near add of +1.50 to +2.50 D, needing a suppression trial; multifocal soft lenses — centre-near or centre-distance simultaneous vision; translating segment designs. - **Monovision acceptance:** roughly two of three presbyopes adapt; trial in spectacles or diagnostic lenses before any permanent surgical commitment; watch night driving. - **Surgical choices:** monovision LASIK or PRK, multifocal and extended-depth-of-focus intraocular lenses at cataract surgery (halo and contrast trade-offs), corneal inlays — all counselling-heavy. - **Uncorrected presbyopia** remains one of the largest causes of near-vision disability among Indian adults over forty; ready-made +1.00 to +3.00 D glasses dispensed at camps answer a large share of it. ## Choosing for three different forty-somethings A 44-year-old schoolteacher with emmetropic distance vision wants comfort for marking books at 35 cm. Her amplitude is 3.50 D; half is 1.75; demand 2.85 D; the addition computes to about +1.25 D — and a progressive satisfies both her board-watching and her marking, with a follow-up at six weeks for adaptation. A 52-year-old shopkeeper who never tolerated glasses wants one solution: trial monovision with −0.25 distance on the dominant right eye and +2.00 near on the left; he reads price tags and drives in daylight, returns reporting night-driving haloes, and settles into a modified monovision of −0.75 intermediate on the left — a frequent real-world landing point. The third is a 58-year-old tailor with −4.00 D myopia who has simply removed her spectacles to sew for years. Removing minus at near is her presbyopia correction already; offering +2.50 over her distance lenses in a flat-top 28 forces an unfamiliar working distance, and the wiser prescription is a pair of −1.50 single-vision "near" glasses — effectively her distance pair cropped for the 33 cm needle point. Same age table, three different answers, because the trade each patient runs (distance clarity, night driving, lifelong habit) differs. ## High-yield viva angles Examiners ask why over-plussing fails: too large an addition contracts the working distance to a sliver, so the patient "can read only two lines." They probe monovision rationale — dominance testing with the hole-in-card method, and why distance-dominant-eye assignment matters for safety-critical tasks. They test bifocal-versus-progressive counselling: image jump and line visibility versus corridor adaptation. And they like the myopic-presbyope paradox: the uncorrected −4.00 D myope is naturally "presbyopia-proof" at her 25 cm focal point — explain why her first cataract surgery can paradoxically worsen near function unless the intraocular lens strategy plans for it. ## Frequently asked questions ### At what age does presbyopia typically begin? Around 40-45 years, when the receding near point encroaches on the usual 33-40 cm reading distance; earlier in hyperopes, later and more gently in myopes. ### How is the near addition calculated? Working-distance demand minus half the measured amplitude of accommodation, then refined on a near chart at the patient's actual working distance. ### What is monovision correction? Correcting the dominant eye for distance and the fellow eye for near, in spectacles or contact lenses or surgically; about two-thirds of presbyopes adapt, so it is always trialled first. ### Why do progressive lenses avoid image jump? Because power increases smoothly along the corridor rather than stepping at a segment line, though at the cost of peripheral astigmatic aberration requiring adaptation. ### Which presbyopia option suits a lifelong emmetrope who only reads at night? A pair of single-vision near glasses — the simplest, cheapest answer when distance needs no correction and the demand is occasional.
