Your vision is a performance factor
I am an ophthalmic surgeon specialised in refractive surgery, and an amateur runner and triathlete. I know what a contact lens shifting at kilometre 30, a pair of fogged glasses on a descent or blurry vision in the water do to a session. This page explains what your sport demands of your eyes, how to correct them without compromise, and which surgery to consider for your discipline — in Boulogne-Billancourt, at the gates of Paris.
Seeing right means anticipating
Vision is the first sense of performance: most of what an athlete processes in action is visual. An athlete who is "roughly" corrected loses anticipation, precision and safety — often without knowing it.
Three things to remember
- 20/20 in the consulting room guarantees nothing in motion. Dynamic vision, contrast and peripheral vision count as much as reading letters.
- A small neglected correction costs a lot. Uncorrected myopia of −0.75 D or one dioptre of astigmatism degrades reaction time and distance judgement.
- Correction must fit the discipline. A swimmer, a boxer and a golfer have nothing in common — neither the risks nor the solutions.
Two paths on this page. You train regularly, in a club or for leisure: the discipline selector and the sports vision assessment are for you. You are an elite athlete, sports physician, coach or club official: go to the dedicated section, with a direct contact form.
The six functions I assess in an athlete
Add to these glare adaptation, twilight vision and eye dominance — decisive in shooting, golf and racket sports.
Static acuity
Sharpness of a fixed target: the baseline, but not the whole story.
Dynamic acuity
Keeping a fast-moving object or scene sharp — something a standard eye test does not measure.
Contrast sensitivity
Picking out a ball, a feature or a marker in mist, rain, water or low light.
Peripheral vision
Perceiving an opponent or a team-mate outside the line of sight.
Binocular vision and depth
Judging the distance and speed of an approaching object.
Eye-hand, eye-foot coordination
Turning visual information into a precise, well-timed movement.
Glasses, contact lenses, orthokeratology
Surgery is not the only answer. At the practice I fit contact lenses designed for sport and orthokeratology; here is what each solution allows, and where it falls short.
Wraparound frame, polycarbonate or Trivex lenses in each eye's prescription, suitable tint: the right option for many non-contact, non-water disciplines. Limits: fogging, rain, reduced field, slipping on sweat, breakage on impact.
No fogging, full field of view. Real limits: dryness with effort and wind, loss mid-match, and above all infection risk in water — I strongly advise against contact lenses in the water without watertight swimming goggles. I fit daily disposable lenses suited to your sport.
Rigid lenses worn overnight temporarily reshape the cornea; by day you see clearly with nothing in. I offer it to athletes who do not wish to, or cannot yet, have surgery: minors, still-progressing myopia, water sports. Reversible when you stop wearing them, with regular follow-up at the practice.
Daily training, early-morning races, water, dust, sweat: the nuisance builds up and many athletes end up consulting. Surgery removes dependence on equipment — provided you choose the technique that fits your sport, which the rest of this page explains.
What your sport demands of your eyes
Choose your family of sports: visual demands, risks, recommended correction, suitable surgery and return timelines. Each card links to a full guide.
Swimming, triathlon, open water
Underwater, the cornea loses its optical power: everyone sees blurry without a mask. What makes the difference is vision out of the water — buoys, pool clock, road signs, transitions.
Read the full guide →- DemandsContrast sensitivity, distance vision for sighting, glare management
- RiskInfection in water: no contact lenses without watertight goggles; dryness
- CorrectionOrthokeratology, prescription swimming goggles
- SurgerySMILE, LASIK or PRK depending on the cornea; ICL for high myopia
- ReturnRunning and cycling day 2–3 · pool with watertight goggles ~week 2 · open water, sea week 4, once cleared
Combat sports, rugby, hockey
A direct blow to the eye is the rule, not the exception. The technique must preserve corneal strength: I favour SMILE or PRK, with no corneal flap.
Read the full guide →- DemandsPeripheral vision, reaction time, binocular vision
- RiskDirect trauma; glasses impossible
- CorrectionDaily disposable contact lenses
- SurgerySMILE or PRK (no flap); ICL with precautions; LASIK reserved for non-contact sports
- ReturnNon-contact cardio day 3 · technique without sparring week 2 · contact with eye protection month 1 · full opposition case by case, month 1 to 3
Tennis, football, golf, basketball, handball
Performance starts with reading the trajectory early. One dioptre of uncorrected astigmatism is enough to degrade vision of a moving ball.
Read the full guide →- DemandsDynamic acuity, depth perception, eye-hand coordination, eye dominance
- RiskBall, elbow or fall impact
- CorrectionContact lenses, wraparound sports glasses or prescription protective eyewear
- SurgeryLASIK or SMILE; SMILE or PRK if contact is frequent (basketball, handball)
- ReturnJogging, static strokes day 3 · training week 2 · matches month 1 with protection if contact
Running, trail, cycling
Wind, sweat, dust, insects, night riding: endurance sports put the ocular surface to the test and punish contact lenses after two hours.
Read the full guide →- DemandsContrast sensitivity, twilight vision, peripheral vision, glare
- RiskWind-induced dryness; foreign bodies; falls on trail and MTB

Which surgery for which athlete?
Four techniques, one logic: the sport first, then the cornea (Anterion topography) and the prescription.
- Contact sports or sports with a risk of impact (combat, rugby, handball, basketball, hockey): I favour SMILE or PRK, techniques with no corneal flap. LASIK creates a flap that remains a relative weak point in the event of direct trauma: I reserve it for non-contact disciplines.
- Competitors who cannot stop for long (endurance, non-contact ball sports): LASIK or SMILE, for visual recovery within days.
- High myopia, thin or irregular corneas: the ICL / IPCL phakic lens, reversible and leaving the cornea untouched, with the same anti-impact precautions in the first weeks.
- Athletes over 45: see the presbyopia in athletes section.
- Water sports: the technique matters less than the time before returning to the water — 2 to 4 weeks without unprotected immersion, whatever the technique.
Criteria common to all refractive surgery
- Over 18, prescription stable for at least 1 year
- Cornea compatible on topography and tomography (Anterion)
- Balanced ocular surface — dry eye is treated before operating
- A sports calendar that leaves room for return timelines

Return timelines by technique
Indicative benchmarks: each step is cleared at the post-operative check-up, and the instructions I give you in consultation always take precedence.
| LASIK | SMILE | PRK / Trans-PRK | ICL / IPCL | |
|---|---|---|---|---|
| Useful vision | 24–48 h | 24–72 h | 1–2 weeks | 24–48 h |
| Walking, indoor trainer | Day 1 | Day 1 | Day 2 | Day 1 |
| Running, road cycling (protective glasses) | Day 2–3 | Day 2–3 | after healing, ~week 1 | Day 2–3 |
| Protective glasses during exercise | ~1 month | 2 weeks | 2 weeks | 2 weeks |
| Pool with watertight goggles | ~week 2, once cleared | ~week 2, once cleared | ~week 2, once cleared | ~week 2, once cleared |
| Unprotected water (sea, open water, surf) | Week 4, once cleared | Week 4, once cleared | Week 4, once cleared | Week 4, once cleared |
| Contact sports with protection | Reserved for non-contact sports | Month 1 | Month 1 | Month 1 |
| Combat, rugby at full opposition | — | Case by case, month 1 to 3 | Case by case, month 1 to 3 | Case by case, month 1 to 3 |
| Scuba diving | Month 1 | Month 1 | Month 1 | Month 1 |
Combat sports and rugby at full opposition are decided together, depending on the technique and your healing.
The sports vision assessment
A dedicated consultation in Boulogne-Billancourt, built around your discipline, your level and your competition calendar.
- Interview on your discipline, level, calendar and current difficulties
- Precise refraction
- Eye dominance and preferred eye
- Intraocular pressure
- Orthoptic assessment: binocular vision, convergence, depth perception
- Ocular surface: looking for dryness worsened by exercise
- Fundus examination
- Anterion imaging: corneal topography and tomography, biometry, anterior-segment OCT
- Functional tests: contrast sensitivity, dynamic visual acuity
- Personalised plan: optical correction, contact lenses, orthokeratology or surgery, timed to your season
Who is it for? Any athlete bothered by their correction or who suspects vision that is "not quite sharp" in action; any candidate for refractive surgery who practises a sport with specific risks or constraints; parents of a young short-sighted athlete wishing to discuss orthokeratology and myopia control.
Presbyopia in athletes: read your watch without losing the trail
Presbyopia catches athletes where they least expect it: the map, the bike computer, the GPS watch, the route card, the score on the phone.
Reading glasses have no place on a bike or a golf course; progressive lenses get in the way on descents and when running because of their lateral blur zone. The solutions I offer, from the simplest:
- Multifocal contact lenses or monovision in contact lenses, tested during exercise before any surgical decision.
- PresbyLASIK for presbyopes without cataract, after a contact-lens trial to confirm tolerance.
- Lens surgery with an EDOF or multifocal lens when the crystalline lens starts to lose its clarity; EDOF lenses keep good distance and night vision, a point I discuss with cyclists and drivers.
The sport guides the choice. The golfer favours intermediate vision (ball on the ground, the green); the cyclist night vision and contrast; the tennis player binocular vision, which limits monovision.
I run, ride and swim as an amateur. I know what a contact lens lost in the first metres of an open-water swim does to an entire race.
That experience led me to build a consultation dedicated to sports vision. It is not a marketing line: it changes how I question an athlete, the tests I run and the technique I recommend. A triathlete, a boxer and a golfer should not leave with the same answer.
