Monovision LASIK is a vision correction procedure that intentionally leaves one eye slightly nearsighted while correcting the other eye for distance vision. This technique, used to address presbyopia, allows the brain to adapt and utilize each eye for its designated focus (near or distance), potentially reducing or eliminating the need for reading glasses.
Your brain blends the two images so you can see far and near without swapping glasses constantly. This approach mainly helps presbyopia—the age-related loss of near focus that usually starts in the 40s. It doesn’t “reverse aging of the lens”; instead, it uses one eye for far and the other for near to cover both ranges. People vary: many adapt well; some feel off-balance, especially for tasks that need sharp depth perception (stereo vision), like threading a needle or judging a bouncing ball at night. EyeWikiAAOScienceDirect
LASIK reshapes the clear front window of your eye (the cornea) with a laser. In monovision LASIK, the surgeon targets emmetropia (no glasses) in one eye for distance and leaves mild myopia (a little minus power) in the other for near. The amount of “difference” between the eyes is chosen to balance near clarity with comfort and depth perception; many centers first simulate monovision with contact lenses to be sure your brain likes it before making it permanent. EyeWikiCleveland Clinic
When we are young, the natural lens inside the eye changes shape easily so we can focus at many distances. After about age 40–45, that lens stiffens. This is presbyopia, and it makes near tasks (phone, menus, sewing) blur. Traditional LASIK can make both eyes sharp at the same distance (usually far), but then you still need reading glasses. Monovision takes a different approach:
Your dominant eye is corrected for distance (driving, TV, faces).
Your non-dominant eye is intentionally left a little nearsighted for close-up tasks (phone, books).
Your brain learns to use the distance eye for far and the near eye for close. Together, they give “functional vision” across daily life. You may still need thin readers for tiny print or dim lighting, but many people go glass-free most of the day.
Dominant eye: The eye your brain prefers for aiming and distance tasks—like the “lead hand” in sports.
Anisometropia: A difference in focusing power between the two eyes (on purpose in monovision).
Neuroadaptation: The brain’s learning phase to blend images from both eyes comfortably.
Each eye sends a slightly different image. With monovision, one image is optimized for far and the other for near. Your brain naturally “picks” the sharper image for the task at hand and filters the blur from the other eye. Most adults can adapt within days to weeks. A smaller difference between eyes is easier to adapt to; larger differences can give more reading power but may reduce depth judgment and night comfort. That trade-off is the heart of the counseling before surgery.
Types of monovision
Conventional monovision
Distance (dominant) eye is targeted for crisp far vision; near (non-dominant) eye is targeted around −1.00 to −1.75 diopters for near. Simple, time-tested.Mini-monovision (or micro-monovision)
A gentler difference (about −0.50 to −1.00 diopters) in the near eye. Easier adaptation and better depth perception, but less reading power—often fine for phone/labels, not tiny print.Blended vision
A planned “blend” where each eye has extended depth of focus using subtle optical choices (and sometimes wavefront-guided profiles). Goal: smoother overlap between far and near.Modified monovision with multifocal/extended-depth ablations (a.k.a. presbyLASIK, center-near or center-distance profiles)
The corneal shape is sculpted to create multiple focal zones, combined with a small inter-eye difference. This can extend range but needs careful screening.Contact-lens trial monovision (before LASIK)
Not a surgical “type,” but a vital step: temporary soft lenses simulate monovision so you can feel how your brain handles it in real life.Monovision after lens surgery (mix-and-match IOLs)
Technically not LASIK, but the concept is the same after cataract surgery: one eye aimed for far, the other for near, sometimes fine-tuned later with LASIK.
Who is (and isn’t) a good candidate
Good matches
40s–60s adults with presbyopia who want less dependence on glasses.
People who tolerate a contact-lens monovision trial well.
Jobs and hobbies that do not require perfect depth perception (e.g., casual sports over professional fast-action sports).
Possible mismatches
People who drive at night a lot (professional drivers, frequent night highway driving).
People whose work demands fine stereopsis (e.g., pilots under certain rules, surgeons in some specialties, precision crafts).
Eyes with irregular corneas, unstable prescriptions, keratoconus, advanced dry eye, significant macular or optic-nerve disease.
Those who tried and hated monovision contacts.
Causes
To keep this practical, “causes” here means reasons success is more likely or reasons side effects/problems appear. Each factor has a short explanation.
Presbyopia severity
The stronger your near difficulty, the more near power you may need in the near eye—helpful for reading but harder to adapt to.Eye dominance strength
Clear dominance helps the brain assign tasks; weak or mixed dominance can make switching between distances feel uncomfortable.Amount of anisometropia planned
Bigger difference = better near range but more risk of depth loss, eyestrain, and night halos.Pupil size (especially in low light)
Larger pupils can increase halos and glare at night, especially in the near-set eye.Higher-order aberrations (HOAs)
Pre-existing optical imperfections can reduce contrast and make blur more noticeable.Dry eye disease
Dry, unstable tears cause fluctuating vision and discomfort—both worse after LASIK if not treated first.Corneal thickness and shape
Thin or irregular corneas limit safe laser range and may risk poor quality vision.Uncorrected astigmatism
Residual astigmatism blurs at every distance and can spoil the monovision balance.Unstable glasses/contact prescription
A changing refraction (e.g., in early 20s or with medical causes) makes any laser target less reliable.Macular problems (e.g., macular degeneration, epiretinal membrane)
Lower retinal clarity reduces the brain’s ability to adapt to monovision.Optic nerve disease (e.g., glaucoma)
Reduced contrast sensitivity makes the trade-offs more obvious and less comfortable.Cataract or lens changes
Early cataract can shift focus after surgery, upsetting the monovision plan.Diabetes control
Poor control can swell the lens and cornea, changing focus and healing.Autoimmune disease and wound-healing issues
Some conditions and medicines slow healing and raise dry eye risk.Medications that worsen dryness (antihistamines, acne meds, some antidepressants)
Drier eyes = less stable, comfortable vision.Night-driving demands
Frequent nighttime driving magnifies halos and depth issues—some people dislike monovision for this reason.High stereo-demand hobbies/jobs
Precision sports or jobs may reveal the small depth-perception cost.Previous refractive surgery
Prior LASIK/PRK changes corneal optics; planning must account for it to avoid surprise blur.Realistic expectations and counseling
Understanding trade-offs improves satisfaction; poor expectations lead to “success technically, unhappy practically.”Neuroadaptation limits
A small group simply cannot adapt; they feel imbalance, eyestrain, or blur despite a perfect surgery.
Symptoms
Mild blur at near or far in one eye (normal and expected; the other eye clears it during tasks).
Temporary eyestrain or “brain fatigue” while adapting in the first days/weeks.
Headaches from switching tasks a lot early on.
Reduced depth perception (e.g., judging steps, pouring, fast balls).
Halos and glare at night (often more noticeable from the near-set eye).
Ghosting or shadowing of edges, especially in dim light or on back-lit screens.
Difficulty with very tiny print or very low-contrast text; a thin pair of readers can help.
Reading fatigue after long sessions; breaks help during adaptation.
Light sensitivity early after surgery.
Dryness, burning, or gritty feeling that blurs intermittently.
Fluctuating vision through the day (often dryness-related).
Needing to squint for small print in dim restaurants.
Monocular double vision (from tear film or residual astigmatism); usually improves with healing/dry eye care.
Dizziness or slight imbalance in fast motion or crowded patterns (early, usually fades).
Persistent dissatisfaction (rare); if present beyond the adaptation window, discuss options like enhancing, reducing near power, or reversing monovision.
Diagnostic tests
To keep it clear, the tests are grouped by category. Each is explained in simple language.
Physical exam
Distance and near visual acuity (each eye and both together)
You read letters at far and near. This shows your baseline and how each eye performs alone and together—key for predicting monovision comfort.Cover–uncover and alternating cover tests (alignment)
The doctor covers one eye then the other to see if the eyes are straight or have a hidden turn. Large misalignment can worsen depth issues in monovision.Slit-lamp exam of the front of the eye and tear film
A microscope checks lids, lashes, cornea, tear quality, and lens. Any dryness or corneal problem must be treated first for stable results.Dilated retinal exam
The inside of the eye (macula, retina, optic nerve) is checked to make sure no disease will limit vision or adaptation.
Manual tests
Manifest refraction (the “which is clearer, 1 or 2?” test)
Finds your best glasses prescription while you answer. It tells what laser change is needed and how sharp each eye can get.Cycloplegic refraction
With drops that relax focus, this reveals hidden farsightedness and how much your lens was “helping.” It prevents surprise over- or under-correction.Eye-dominance testing (hole-in-card or Miles test)
Simple pointing tests show which eye your brain prefers for aiming. That eye usually becomes the distance eye.Trial monovision with a phoropter or trial frames
In-office lenses simulate the planned near power so you can feel it instantly before any procedure.Stereoacuity (depth perception) tests (e.g., Titmus/Randot)
Measures fine depth. If depth is already poor, strong monovision may be uncomfortable.Accommodation testing (amplitude and facility)
Measures how much close-focus power you still have and how quickly you switch focus—important when choosing mini- vs. full monovision.
Lab and pathological tests
Tear osmolarity
A tiny tear sample checks saltiness; high numbers mean dry eye. Treating dryness first improves clarity and comfort after LASIK.MMP-9 inflammatory marker (point-of-care dry eye test)
Detects surface inflammation that can blur and delay healing. Positive results guide anti-inflammatory tear therapy before surgery.Blood sugar control (e.g., HbA1c or fasting glucose) when indicated
Poor control can shift focus and slow healing. Optimizing it makes results more stable.
Electrodiagnostic tests
Visual evoked potential (VEP) — rarely, if needed
Checks the vision pathway from eye to brain. Used when optic-nerve issues are suspected that might limit quality after LASIK.Electroretinography (ERG or pattern ERG) — if retinal disease suspected
Measures retinal cell function. If weak, even perfect optics will not look sharp, which matters for monovision planning.Objective pupillography (dynamic pupil reflex recording)
Automated recording of how pupils react to light. Oversized low-light pupils may predict nighttime halos and guide targets.
Imaging tests
Corneal topography
A color map of corneal curvature. It screens for irregular shapes (like keratoconus) that make LASIK unsafe or lower quality.Corneal tomography with pachymetry (e.g., Pentacam)
3-D cornea map plus thickness at every point. Confirms there is enough tissue to remove safely while keeping the cornea strong.Wavefront aberrometry (higher-order aberrations)
Measures subtle optical imperfections that cause halos or smearing. Helps customize the plan and predict night comfort.Optical coherence tomography (OCT) of macula/optic nerve (as indicated)
A detailed “ultrasound-like” light scan. Finds macular puckers, early membrane, or nerve issues that could limit monovision success.

Surgical pathways
Monovision LASIK (the core procedure)
What happens: corneal flap creation + excimer laser reshaping; dominant eye targeted for distance, fellow eye for near.
Why: reduce or eliminate dependence on reading glasses while keeping good distance function overall. EyeWikiMonovision PRK
What happens: surface laser reshaping without flap; same monovision targeting.
Why: option when corneas are thinner or if flap is undesirable; healing is slower than LASIK. (See PRK medication/indication resources.) FDA Access DataSMILE with micro-monovision
What happens: femtosecond laser removes a lenticule via a tiny incision; mild near bias in one eye.
Why: small incision technique; some centers use it for presbyopic “mini-monovision.” (Outcomes reported in studies; center-specific.)Presbyopic laser profiles (e.g., “blended vision”)
What happens: reshape optics to extend depth of focus, often combined with a mild monovision offset.
Why: to widen the range of clear vision and reduce dependence on readers.Lens-based options (cataract surgery or refractive lens exchange) with monovision
What happens: replace the lens with monofocal IOLs set for distance in one eye and near in the other; or use EDOF/multifocal IOLs to reduce glasses.
Why: preferable when presbyopia coexists with early lens changes/cataract or if corneal surgery isn’t ideal. (AAO discusses monovision choices in cataract settings.) AAO
Note on corneal inlays: once popular for presbyopia, most have been withdrawn/discontinued in the U.S. in recent years; they are rarely offered now. (Market withdrawals reported 2022–2023.)
Practical prevention tips
Get a contact-lens monovision trial first (if available) to test tolerance. Cleveland Clinic
Treat dry eye/MGD before surgery (lid hygiene, tears, compresses); optimize the surface first. tfosdewsreport.org
Be realistic about depth perception—expect some stereo reduction; avoid extreme anisometropia. ScienceDirect
Night driving plan—consider “driving glasses” initially.
Protect your eyes with UV-blocking sunglasses outdoors. National Eye Institute
Screen ergonomics + 20-20-20 to limit evaporative blur. AAO
Follow the drop schedule exactly after surgery (antibiotic/steroid/lubricant). FDA Access DataDailyMed
Pause contacts and makeup when instructed post-op to lower infection risk.
Know the warning signs (below) and seek urgent care if they occur.
Keep regular eye exams to monitor stability and ocular health. National Eye Institute
When to see a doctor
Right away (urgent): sudden drop in vision, severe pain, new flashes/floaters or a curtain over vision (possible retinal tear/detachment), pus-like discharge, marked light sensitivity, or a feeling that a “flap moved.” These require same-day assessment. (Miotics like pilocarpine carry retinal warnings; act fast if symptoms occur.) FDA Access Datavuitypro.com
Soon (within days): persistent blur, significant halos/night glare not improving, foreign-body sensation or dryness not relieved by lubricants.
Routine: scheduled post-op checks and annual exams to keep tabs on refraction and ocular surface.
What to eat
Eat more of:
Leafy greens (spinach, kale, collards).
Orange/yellow veg (carrots, sweet potatoes) for provitamin A.
Oily fish (salmon, sardines, mackerel) 2–3×/week for omega-3s.
Citrus/berries for vitamin C.
Nuts/seeds (almonds, walnuts, chia, flax) for vitamin E and healthy fats.
Eat/Drink less of:Ultra-processed, high-sugar foods (worsen inflammation).
Excess alcohol (dehydrates).
Very salty snacks (can dehydrate).
Smoke exposure (avoid entirely).
Mega-doses of preformed vitamin A (avoid >3,000 mcg RAE/day unless directed). National Eye InstitutePMC
Frequently Asked Questions
1) Is monovision LASIK permanent?
The corneal reshaping is permanent, but your natural lens still ages, so near vision can change over time. Fine-tuning with glasses or enhancement can be considered later. EyeWiki
2) Will I lose depth perception?
Expect some reduction in fine stereo depth; most daily tasks are fine, but some people notice it in night sports or precise work. A smaller near offset (“mini-monovision”) preserves more stereo. ScienceDirect
3) How do I know if I’ll tolerate it?
Do a contact-lens monovision trial for days to weeks. If you’re comfortable, surgical monovision is more likely to suit you. Cleveland Clinic
4) What side effects happen after surgery?
Temporary dryness, halos, glare, and fluctuating clarity are common early and usually improve with lubricants and time. Follow your drop plan to lower inflammation and infection risk. tfosdewsreport.orgFDA Access Data
5) Can I still wear glasses sometimes?
Yes—many people keep night driving glasses or low-power readers for tiny print.
6) Is pilocarpine (VUITY) an alternative to monovision LASIK?
It’s a temporary, daily drop that narrows the pupil to sharpen near; it can help if you want to avoid surgery or as a backup after surgery. Rare retinal risks exist—screening is wise if you’re myopic or have retinal issues. FDA Access DataPubMed
7) What if I already have dry eye?
Treat lid gland function and ocular surface before surgery (compresses, hygiene, lubricants; add Rx drops if needed). Well-managed dry eye improves comfort and optical quality. tfosdewsreport.org
8) How quickly will I adapt?
Many adapt within days to weeks; a minority never like it and may prefer glasses or different surgical plans. Cleveland Clinic
9) Can I reverse monovision LASIK if I hate it?
Options include an enhancement to change the target, using glasses/contact lenses, or (in lens-based cases) changing IOL strategy. Discuss reversal probability before surgery.
10) Is SMILE/PRK as good as LASIK for monovision?
They’re different techniques with pros/cons; some centers offer “micro-monovision” SMILE or monovision PRK. Your cornea, prescription, and lifestyle decide the best fit.
11) Will I still need readers sometimes?
Likely for tiny print or prolonged near work—monovision reduces dependence; it doesn’t guarantee zero readers for every task.
12) What about corneal inlays?
Most inlays have been discontinued in the U.S.; today’s choices are mainly contacts, laser (LASIK/PRK/SMILE), or lens-based solutions.
13) What drops are typical after LASIK?
A short course of antibiotic and steroid, plus lubricants; regimens vary by surgeon and surgery type. FDA Access DataDailyMed
14) I drive at night a lot—am I a candidate?
You can be, but discuss a smaller near offset or a task-specific distance pair for night driving to maximize contrast.
15) What lifestyle changes help vision comfort after surgery?
Use the 20-20-20 rule, blink fully, humidify your workspace, and follow a leafy-greens + omega-3 fish diet pattern. AAONational Eye Institute
