March madness showcases how much some athletes have to move and shift their eyes while coming down the court and others don't.
This is called gaze control and elite athletes have better gaze control. They don't shift their eyes as much.
One reason average athletes move their eyes more is because their area of vision is smaller than that of the elite.
Our central vision gives us our best vision and we can measure this on athletes. In my book, See To Play, we describe this area as the detailed vision zone and how to measure for it. Average athletes see detail in less than 30 degrees of one gaze while the best athletes see over 50 degrees. (I met with professional basketball trainer, Joe Sharpe, this summer and this fact really impressed him...so much so that he thanked me by sending a Kevin Durant, Russell Westbrook and OKC Thunder signed ball.)
Let’s compare two basketball point guards standing at the top of the three point line. The average athlete will have to shift their eyes 5 times to see from one side of the court to the other. The better athletes can see that same area with just 2 shifts of eye gaze. The better athlete moves his eyes half as much, takes in the same information and performs that task in a shorter amount of time.
Eye gaze has been studied on athletes by measuring how much athletes move their eyes. These studies found that better athletes move their eyes less and their eyes don’t jump as much before decision making. This is often referred to as a quiet eye. Brain activity was also measured to be less before decision making with these athletes.
This raises the question: does this occur because athletes are more mentally prepared or are there other factors?
I believe that the biggest factor is how much an athlete sees (i.e., athletes who exhibit large detailed vision zone take in more information in one gaze, can get the whole picture of the playing field in a shorter amount of time allowing for less processing and quicker decision making.) I hope this will be studied more by the quiet eye folks.
So, which came first? The chicken or the egg…………….or in this instance….is gazed controlled by the size of the detailed vision zone or the amount of thinking?
I’ll take the athlete with the larger detailed vision zone!
Enjoy watching the March Madness Eye Movements!
Ask anybody why a pirate wears an eye patch and they'll tell you "because his eye got poked out by a sword fight".
But, the real reason lies with nighttime vision versus daylight vision.
Have you ever gone to the movie theater on a very bright sunny day. As you walk into the theater, you realize you can't see. Everything is so dark. Your eyes were adjusted to the daylight and now have to go through a period of adjusting to the dark.
This adjustment is because the receptors in the eyes, the rods and cones, are switching on and off. Daylight vision uses cones. Nighttime vision uses rods. So, there is a period of time where one type of receptor has to get warmed up while the other shuts down. (This is a main reason why vision at dusk is difficult.)
It's believed Pirates wore eye patches so that they could adjust their vision from the bright sun on the top deck, to the vision needed in the dark lower levels of the ship...in particular...where ammunition and cannon's were housed.
The patch would be used to protect the vision in the eye that the pirate would want to use in the darkness of lower levels of the boat. He would merely need to flip up the patch that was over the eye and that eye would be ready to see in the darkness of the underneath.
People who have their eyes examined at the eye doctors notice this phonemenon to some extend. The eye doctor usually shuts off the left eye while testing the right eye. After testing the right eye, the doctor will open up the block over the left eye and block the right. Many times, patients notice that there is an orangish glow or hue when the left eye is opened up. This occurs because the left eye has begun to dark adapt and the cones have to readjust.
So, the next time you see a pirate wearing a patch...just realize they want to be ready to see in the dark!!
First, the statistics:
Problems with vision is the common denominator in the lack of success with athletes playing a sport and learning.
Former President, Mr. Bill Clinton and LA Lakers' Kobe Bryant lead a panel this week which opened the Clinton Health Matters Initiative Conference. Their focus was barriers to access, coaching quality and safety to help improve children becoming more active and fit. Nike jumped in to help with a new initiative to help promote this message as well.
This "build it and they will come" approach can work, but I hope we don't miss the opportunity for a bigger message: build with a solid foundation. As the statistics point out, that foundation is a properly working visual system.
In an effort to make sure kids could see in North Carolina, we passed a bill in 2005 mandating eye exams for all children entering kindergarten. Farsightedness (which is the most prevalent vision issue at a young age) interferes with the eyes ability to get a clear focused image to the brain (we can't focus) as well as throwing off the body's coordination by causing reaction time to be too fast. Nearsighted kids can't see to get clear images from the board and slow down reaction time in sports.
The law was repealed before it was implemented.
we are waking up to the fact that almost 50,000 third graders will have to attend a six week reading boot camp during the summer in order to acquire the proper reading skills to advance to the fourth grade. Kids are falling behind. Are we reaping what we sow?
I hope you'll join me in my mission in helping kids reach their genetic potential...both in sports and in the classroom!
Get them to the eye doctor.

Reached the 200 mark of patient concussion encounters for the year 2013.
Why did Florida State's quarterback and Heisman hopeful, Jamies Winston quit squinting? The simple answer: Peer pressure! He was "peer pressured" in to wearing his contacts. (At least that's my bet, all eyes are off him since he lost his squint!)
Peer pressured to wear contacts?! That statement sounds odd, doesn't it? Most people won't wear their glasses or contacts because they are called a nerd.
Tonight's ACC football championship game has been titled the colossal match of a David versus Goliath. The Cinderella team, Duke, against perennial power house and national championship hopeful, Florida State. Duke faces heavy odds to win this game.
Athletes who need to wear glasses or contact lenses to see their best face heavy odds against making into the professional sports ranks.
2 out of 5 athletes won't make it to the NFL because of their vision. Only the best eyes make it.
Sure, Winston has been phenomenal playing when he was playing without contacts, but why did he choose to be less than perfect? Why not choose to push the envelop on being the best athlete ever to play that possition.
It turns out his national squinting fit may have been the best thing to happen to him. Being chastised for his squint may have been all the motivation he needed to start wearing his contacts more.
Now, if he plays without them, he will consciously have to think about "not squinting" during tonight's game. If he has to think about "not squinting", his mind will be off his game. Rainy, nighttime games are the conditions that make it the hardest for athletes to see to play.
My eyes will be on seeing if Winston squints. I'm sure he won't.... and I'd hope a reporter asks him after the game if he wore his contacts..... even though I know this was yesterday's news.
All eyes are off the Winston squint.....except mine!
I thought I would give you an update into the question, "Does Jameis Winston's Squint Affect his Stats"
This is his stats night games versus day:
Night Games Day Games
Completion ptg 72 % 68 %
Yards passing/game 318 270
Intercept/game .75 .7
TD/Game 2.5 3.14
Pretty much a wash!
See To Play is officially 3 years old today! Happy Birthday!
I hope you all have enjoyed my blog. I have really enjoyed getting all your emails and questions. Keep them coming!
The most important thing is touching more lives so that athletes realize...if they aren't seeing their best, they won't be their best! You Gotta See To Play!!
This blog is a “Cliff Note” version on why athletes squint, performance problems, inclusion of the Jameis Winston squint topic, and ways to improve athletes’ vision.
Astigmatism: Without using glasses or contacts, causes night time vision to be worse. Players in these conditions will squint more during night games and perform worse. Jameis states his vision doesn’t affect his game. Looking at his stats and assuming he has not worn his contacts in any game, he is correct when he states his vision hasn’t affected his game. His completion percentage and yards passing is better at night while having less interceptions. His TD/game is higher in daytime. (*see below)
2 out of 5 athletes won’t make it to the professional level because of less than perfect vision. This year’s survey of the NFL shows that 18% of them wear glasses, contacts or had refractive surgery compared to 60% of their peers in other professions.
Avaira Toric contacts: They’re the thinnest, most comfortable on the market that I’ve found for athletes who are very sensitive to the feel of contacts. This is what I would use with Jameis and urge him to wear them.
LASIK: Jameis is too young. Eyes usually stop changing around 24 or 25 years of age and start again mid 30’s to 40’s. He’s gotta wait.
Ortho-k: Evidently, there is a facebook account stating that Jameis has done this in the past. Ortho-K patients wear hard contacts at night while sleeping. This pushes the front part of the eye back into a position so the patient doesn’t need glasses during waking hours. (Astigmatism is a condition where the front part of the eye is shaped like a football. Eyes need to be basketball shaped to see clearly. This procedure pushes the football shaped cornea into a basketball shaped cornea while sleeping.) The problem with this procedure for athletes is that during the day, when the lenses are off, the corneas want to go back to their natural position. So, at night, the eyes are at their worse again. (Here’s an analogy: The Boston Redsocks decide to make better looking beards without cutting them. To do this, special netting is worn over the beards during sleep to push them back. The beard will be less long and bushy because it has been matted back during sleep…guess what…that beard is going to go back to its natural length by game time!!)
Eye glasses: Ok option but get sweaty and hard to see through in a football helmet.
Prescription helmet shields: This is a misnomer. There is actually no prescription in the football helmet shields to correct vision. They are prescribed by doctors to protect eye health or help athletes who suffer from light sensitivity due to medical condition.
Shame on Florida State Medical Staff if this is true (and I don’t think it can be)! Follow this link to hear Jameis in an interview about his vision. One of his statements is that he just went to the eye doctor last week for his annual exam. Athletes, especially a Heisman trophy candidate, should be checked at the beginning of each season… to correct vision if needed and practice with new vision. Then, athletes should be checked again at the end of a season to re-evaluate how to improve vision off season with eye exercises, newer technology in contacts or surgery.
Dollars: No one in the sports world really cares if you fail except the people invested in you. Athletes are replaced over and over. There is a beginning and an end. Your opposition hopes you fail.
You matter to yourself though. Why go through all the hard workouts and the tremendous dedication to become the best…but then chose not to have the best vision? You cannot reach your genetic potential without seeing your best. Seeing less than perfect is being less than perfect. No matter how great you are now, you could be greater seeing better. You’ve pushed and motivated yourself to better performance; now do that with your eyes.
The phobia of “putting something in your eye” has derailed a lot of athletes. Being around eye doctors that can’t correct you or people that won’t push you to “see your best” has derailed athletes as well. 2 out of 5 of you won’t go pro due to your eyes.
*Jameis stats this year Fla. State:
Night Games Day Games
Completion ptg 72 % 67 %
Yards passing/game 318 278
Intercept/game .75 .8
TD/Game 2.5 3.2
What does it all mean? Either Jameis doesn't have vision problems and likes to squint, he is having vision problems, squints and is beating the odds right now (meaning night time stats will crash...case in point, Dan Uggla), or he could be doing even better if he would wear his contacts.
Every 13 minutes, an emergency room in the United States treats a sports-related eye injury.
43% of these eye injuries are to children from ages 14 and younger; 72% of those injured are 25 and younger.
Basketball is the number one overall sport for eye injuries with around 6,000 people hurt annually. Basketball eye injuries are also the most common sports related injury in the category of 15 years old and up.
Corneal abrasions are the most common type of eye injury (as evident by the picture above!).
Baseball is the leading cause of sports related eye injuries in the 14 year old and younger category. The majority of these injuries occur when the athlete is fielding the ball as opposed to hitting. Bi
So, here is the estimated overall injuries a year by sports category:
4,500: Water and Pool activities
4,200: Guns (air, gas, spring, BB)
2,300: Health Club (exercising, weight lifting)
The sports related "vision" injury that I treat the most is concussions which have a visual component. In other words, the part of the brain that is in charge of determining what we are seeing is concussed. This causes athletes to have blurred vision, motion sickness, light sensitivity, poor focus and dizziness.
It is estimated that there are 300,000 sports related concussions per year. The general consensus is that most of these have a visual component but that these injuries heal the quickest. I treat athletes who have lingering visual problems usually after two weeks from impact.
With the NBA starting it's season, I thought I'd give you some fun stats in the world of sports and eye injuries. Work hard, play hard but don't...shoot your eyes out!
It's that time of year.....Halloween! Ghosts, Goblins.....and people wearing all types of costumes.
This is also the time of year when many people get contact lenses to make their eye look...well...hideous!
Wild Eyes contact lenses are most popular lenses two wear with Halloween costume. The lens is tinted or colored with opaque material to change the appearance of the eye to the desired effect. There is a clear area in the middle of the lens that the pupil can see through so that vision is not blocked completely.
These lenses are thicker. So, people who wear them definitely feel them.
Freshlook contact lenses are tinted lenses that many people wear throughout the year to change the appearance of their eye color. In the picture to the left, you'll notice the person's pupil peering through the clear section in the middle of the contact lens. This clear central area needs to be centered over the pupil so that the person can see clearly. If these lenses shift off center, there is a big decrease because of the tints opaque nature.
Tints are also used in contact lenses to help improve athletes depth perception. This can also help them see the ball better.
The picture to the left shows the Nike Maxsight lens which was popular about 10 years ago. Now, athletes can choose to have lenses special ordered with an amber or yellow tint.
One of the biggest problem with tinted lenses, however, is that vision can be bothered in low light conditions or evening games
Have a safe and happy Halloween!!
