I am right-handed. But my dominant eye is my left eye. I discovered this not on a golf course, but while playing tennis, when a coach made me realise that the way I perceived the ball and positioned myself was not quite what I had assumed. For a golfer, that discovery immediately raises another question: can crossed eye-hand dominance affect the way we aim, putt or even swing a golf club?
The subject is far from anecdotal. Jack Nicklaus, a right-handed golfer, described his left eye as his “master eye”, the eye through which he primarily viewed the ball. He even associated this characteristic with the position of his head during the backswing. But somewhere between observations made by great players, theories developed by coaches and what scientific research can actually demonstrate, eye dominance in golf has accumulated its fair share of myths.
A study published in 2025 provides particularly valuable evidence. Researchers assessed laterality in 71 male professional golfers, all ranked inside the world’s top 500. Their findings are considerably more nuanced than some of the theories traditionally associated with eye dominance: visual laterality may be worth considering, but there is no simple dominant-eye profile that automatically produces better golfers.
Being right-handed does not necessarily mean being right-eye dominant
Handedness is easy to understand. Most of us naturally favour one hand for writing, throwing or performing precise movements. Ocular dominance is more complex. When the visual information provided by our two eyes has to be prioritised, the visual system can favour one eye over the other.
Hand and eye dominance can be on the same side: a right-handed person may also be right-eye dominant. This is usually described as uncrossed dominance. But a right-handed person can also be left-eye dominant, and vice versa. This is known as crossed eye-hand dominance.
That distinction matters in golf because aiming, alignment and movement all depend, to varying degrees, on the relationship between what the player sees and how the body organises itself around the ball. Yet even the apparently simple question of which eye is dominant is less straightforward than it first appears. Different testing methods can produce different classifications, and ocular dominance itself is not necessarily an absolute characteristic that behaves identically in every visual task.
This is one reason why claims that a fixed percentage of the general population has matching eye and hand dominance should be treated cautiously. The prevalence of crossed dominance varies according to the population studied and, importantly, according to the method used to measure it.
Golf, however, appears to be particularly interesting in this respect. Research has repeatedly identified crossed laterality among golfers, including elite players. What those observations do not establish is that crossed dominance makes someone a better golfer. A characteristic being relatively common among accomplished players is not evidence that the characteristic caused their success.
What 71 elite professionals revealed
To investigate the question in a population that really matters to golf, researchers collected laterality data from players competing at the 2023 Irish Open. The study, subsequently published in the Journal of Sports Sciences in 2025, involved 71 male professionals, representing 47% of the tournament field. Every participant was ranked inside the world’s top 500. Their average world ranking was 255 and, on average, they had been professional golfers for 12.6 years.
The researchers did considerably more than simply ask whether the players were left- or right-handed. They recorded hand preference, eye dominance, foot dominance and golf stance, then examined those characteristics in relation to performance indicators including world ranking and strokes-gained statistics.
Of the 71 professionals, 44 — 62% — were right-eye dominant, 25 — 35% — were left-eye dominant, while two showed no clear ocular dominance. Since 69 of the 71 players combined right-handedness with a right-handed golf stance, a substantial proportion of the left-eye-dominant golfers consequently displayed crossed eye-hand dominance.
That is interesting. But it is not the most important finding.
When the researchers compared laterality with performance, the relationships between hand dominance, eye dominance, golf stance and playing performance were limited. Some associations appeared when combinations of hand, eye and foot dominance were considered, but the results did not reveal an ideal laterality profile for elite golf.
In other words, crossed eye-hand dominance exists among some of the best golfers in the world. That does not mean being right-handed and left-eye dominant provides a ticket to the PGA Tour.
Putting is where things become more interesting
If there is one area of golf in which dominant-eye research deserves particular attention, it is putting. Not because one form of ocular dominance automatically creates better putters, but because adopting a putting posture changes the visual conditions under which a golfer sees the ball, the intended start line and the target.
A particularly useful study by Kristine Dalton, Michel Guillon and Shehzad Naroo, published in Optometry and Vision Science in 2015, examined 31 golfers: 14 amateurs, seven club professionals and ten top professionals. Instead of measuring eye dominance only while participants stood upright and looked straight ahead, the researchers also measured it while the golfers adopted their putting gaze.
The findings challenge some of the simplest advice traditionally given to golfers.
Eye dominance measured in primary gaze was not equivalent to dominance measured under putting conditions. The magnitude of ocular dominance was also significantly reduced during the putting-gaze test. Most importantly, the researchers found no evidence that crossed eye-hand dominance was associated with a higher level of putting skill. Their conclusion was practical: coaches considering visual strategies should assess ocular dominance both in primary gaze and under putting conditions.
For the amateur golfer, this may be the most useful lesson of all. Knowing your dominant eye provides information. But that information only becomes genuinely relevant when it is considered in the context of the task you are actually performing.
Should your eyes really be directly over the ball?
An older experiment produced a result that should interest anyone who has ever been told that the eyes must always sit directly above the ball when putting.
In 1995, researchers Gregg Steinberg, Shane Frehlich and Keith Tennant studied 48 novice golfers. Half were “pure dextral” — right-hand and right-eye dominant — while the other half were right-handed but left-eye dominant. Participants putted towards a target 3.66 metres away under two conditions: with their eyes directly above the ball and with their eyes positioned approximately five centimetres closer to their feet.
The interaction between eye-hand laterality and eye position was significant. The right-hand/right-eye-dominant golfers produced lower absolute and variable error when their eyes were positioned between the ball and their feet rather than directly over the ball. The crossed-dominance group did not respond in exactly the same way.
The experiment certainly does not establish a universal putting rule. It involved only 48 novices. But it raises a much more useful question: what if the theoretically “correct” eye position is not perceptually optimal for every golfer?
Another study, published in 2005, approached the issue differently. Forty-seven right-handed Japanese physical-education students attempted three-metre putts using both right- and left-handed stances. Right-eye-dominant participants performed better from a right-handed stance, while left-eye-dominant participants showed the opposite pattern. Again, these were inexperienced players, so the findings are nowhere near sufficient to recommend that golfers change sides according to their dominant eye. They do, however, provide further evidence that eye dominance, stance and target perception can interact.
Jack Nicklaus may have found his solution — not ours
Great champions remain fascinating case studies, provided their individual characteristics are not turned into universal laws of biomechanics.
Jack Nicklaus is perhaps the best example. A right-handed golfer with left-eye dominance, Nicklaus described his left eye as his master eye and developed a head position that allowed him to organise his view of the ball around his own visual characteristics.
That is significant because it illustrates how an elite player can build a highly effective movement around his individual perception. It does not prove that left-eye dominance created Nicklaus’s swing, nor does it mean another right-handed, left-eye-dominant golfer should copy his head position.
The distinction matters. An individual characteristic can help explain why a particular position works for one player without making that position a prescription for everyone else.
And what about Phil Mickelson?
Golfers who play from the side opposite their natural handedness add another dimension to the debate. Phil Mickelson is the obvious example: naturally right-handed in many everyday activities, he plays golf left-handed. This kind of configuration has sometimes been linked to eye dominance, but the available research suggests another avenue may be more relevant.
A 2022 study examined 150 golfers divided across five handicap categories and also included interviews with 12 players using what researchers described as a “reversed stance” — playing with the preferred hand at the top of the grip rather than at the bottom. Professional and Category 1 golfers in the sample were 21.5 times more likely to use a reversed stance.
The researchers could not explain this association simply through ocular dominance. One hypothesis instead concerns the role of the preferred hand when it is positioned at the top of the grip and how that may influence control of the movement.
The study is interesting precisely because it separates two ideas that are sometimes confused. Playing golf from the side opposite your natural handedness and having crossed eye-hand dominance are not the same phenomenon. And Mickelson’s extraordinary short-game ability certainly cannot be reduced to one neurological or visual characteristic.
The full swing remains largely a territory of hypotheses
This is where the scientific evidence becomes much thinner.
It is easy to construct an attractive theory. A right-handed golfer who is left-eye dominant might keep the ball in view differently during the backswing, potentially affecting head position, shoulder rotation or the way the player perceives the ball throughout the movement. Nicklaus’s example makes such a hypothesis intuitively appealing.
But the evidence available today does not justify turning that hypothesis into a rule.
Most importantly, the 2025 study involving 71 elite professionals acts as a useful reality check. If one particular eye-hand configuration created a substantial mechanical advantage in the full swing, we might reasonably expect a strong performance signal among a population of world-class golfers. That is not what the researchers found. Associations between eye dominance, hand dominance, stance and performance were limited.
Dominant eye should therefore be considered as one variable within the individual organisation of a golfer, rather than as a hidden programme controlling the swing.
How can you identify your dominant eye?
The simplest test requires no equipment. Select an object several metres away. Extend your arms and create a small opening with your hands, keeping the object centred within it while both eyes remain open. Then close one eye at a time. The eye through which the object remains most closely centred is generally considered your dominant eye for that particular sighting task.
But the 2015 research provides an important warning: do not attach too much importance to that result in isolation. Eye dominance measured while looking straight ahead and dominance measured under putting conditions are not necessarily equivalent.
For a golfer, the more interesting experiment therefore begins on the putting green.
Find a straight putt and use either a line on the ball or an alignment stick on the ground to establish an objective reference. Take your normal address position without deliberately trying to place your eyes directly over the ball. Observe how the line appears, step away and repeat the process with slightly different eye positions.
The purpose is not to find the position supposedly prescribed by your dominant eye. It is to discover the position from which an objectively straight line actually looks straight to you.
That distinction is fundamental.
What should golfers actually do with this information?
Discovering that you are right-handed but left-eye dominant is not, by itself, a reason to change your grip, shorten your backswing, switch sides or rebuild your technique. The scientific literature does not support such prescriptions based solely on ocular dominance.
The information can become useful, however, when a specific problem appears. If you repeatedly feel perfectly aligned when measurement shows that you are not, if a straight putt appears misaligned once you take your stance, or if your head position changes significantly as you try to see the target, the visual component deserves investigation.
Putting is the obvious place to experiment. Treat the process rather like a fitting session: measure before correcting. Test different eye positions, check the actual orientation of the putter face, compare perception with reality and look for the setup that produces the most repeatable results.
The studies conducted in 1995, 2005 and 2015 do not tell golfers that one eye position is universally correct. In many respects, they tell us something more valuable: the interaction between vision, laterality and putting is too individual to be reduced to a single rule.
Your dominant eye matters — but it does not decide your golf
For years, dominant-eye theories in golf have offered a tempting explanation: crossed eye-hand dominance appears relatively common among accomplished golfers, therefore it must provide some kind of mechanical or perceptual advantage.
Modern research requires much more caution.
Yes, crossed laterality is present among elite golfers. Yes, eye position can influence perception and putting performance. And yes, exceptional players such as Jack Nicklaus have clearly developed techniques compatible with their own visual characteristics. But the evidence does not show that one dominant eye makes a golfer inherently better at putting or striking the ball.
The 2025 study of 71 world-class professionals is perhaps the clearest reminder of that distinction. Elite golf contains many different laterality profiles, and eye dominance alone explains remarkably little about who performs best.
So I remain a right-handed golfer with a dominant left eye. Knowing that may help me understand some of the things I perceive on a golf course — just as it has helped me understand certain sensations on a tennis court. But it provides neither a secret advantage nor a convenient explanation for my bad shots.
And that may be the most useful conclusion of all: understanding your dominant eye can help you individualise your golf. It should never be used to invent another universal law of the swing.
