The eye is amazing. Did you know more than 1.9 million fibers come from the eye into the brain? Each of those fibers creates its own pathway to the brain and has its own distinct function. So when someone has a stroke or other acquired brain injury (ABI), vision is often affected. ABIs include concussions suffered in severe sports-
Syntonics, or optometric phototherapy, is a form of light therapy used to treat a variety of vision problems. It is available at Family Eyecare Associates to help patients with a variety of vision problems, such as strabismus (eye turns), amblyopia (lazy eye), focusing and convergence problems and learning disorders. It has also been shown to be very effective for people who suffer from migraines.
Behavioral optometry starts with the concept that vision is learned. When we’re born, we don’t know how to use our arms, legs and hands. We also don’t know how to use our eyes. We have to learn how to integrate them with the rest of our body. The brain must process what the eyes are seeing, and then it has to integrate that information with the other senses. From a behav-
As you begin making your resolution to be healthier this new year, don’t leave out two of the most important parts of your body: your eyes. With the demands that are put on our eyes every day, it is essential to take care of them and even exercise them to strengthen them and possibly improve your vision.
Whether they’re swinging at a fastball, shooting free throws, lining up a putt or setting up a dig, athletes depend a great deal on their vision. They have to keep their eye on the ball in order to connect properly and hit a homer, make the basket, sink the putt or send a spike between two opponents. Many pro teams have a vision therapy program for their players. The program works on improving the athletes’ recognition and response. A sports vision therapist will show a baseball player .....
Professional sports teams, as well as high school and college teams, are increasing their awareness and protocols for assessing acquired brain injury, also known as concussions. Teams want to be sure their athletes are 100 percent ready to return to the field after suffering a concussion. One crucial thing a concussion does is affect your ability to point your eyes, so a prime way to evaluate the severity of a hit is through eye tracking. Eye tracking measures the eyes’ ability to work together.
The American Optometric Association recommends preschool children receive a complete vision exam at the ages of 6 months, 3 years and 5 years. It is particularly important a child have a complete evaluation in the summer prior to entry into kindergarten. Kentucky was the first state to make a law that says you have to have an exam by a optometrist or ophthalmologist the first time you enter Kentucky public schools. The main thing is to make sure children are seeing the black/ whiteboard.
Vision involves over 70% of the neural pathways of the brain. Vision is more than eye sight. Vision is the only body system that continues to develop after birth. Vision involves the way the eyes and brain interact. It takes approximately three years for the eyes to learn how to work together. When they do not, it can result in the eyes turning in (esotropia) or out (exotropia), crossed eyes (strabismus) or lazy eye (amblyopia).
Unlike some other skills we use in our everyday lives, driving relies almost exclusively on our sense of sight. We feel our feet on the ground as we move about or know we are sitting in a chair; we are fully aware of our surroundings. This sensory information lets us know where the ground or chair is. When you are driving, there is no movement of your body. It is totally about your vision and how precisely your two eyes work together. If your eyes are not aligned perfectly, you may think an.....
If you are coming in to your 40s, you may be noticing that your eyesight is changing. You have to strain a little to read, holding the book or newspaper farther away, or you find you need to wear bifocals. You may even notice a bit of clouding of the lens of your eyes. What is going on? Your eyes, like many other parts of the body, are showing signs of aging. The Crystalline lens in your eye is becoming less flexible. This makes it more difficult for the lens to adjust and focus when you look from far to near.
Age takes its toll on all parts of the body, even the eyes. While conditions such as glaucoma are not necessarily inevitable as we get older, they are still possibilities that can change the way we see. It always pay to practice foresight – it just may save your eyesight. Glaucoma is a rather complex disease. Simply put, it occurs when fluid pressure builds up in your eyes. Approximately two and a half quarts of fluid, called aqueous humor, pumps through the eyes every day, providing.....
Visual efficiency is more than 20/20 vision, and there is much more to reading problems than dyslexia or ADHD. About 85 percent of schooling is visual-
A concussion, also known as a traumatic brain injury (TBI) or an acquired brain injury, can adversely affect vision. Unfortunately, possible visual problems are often overlooked during the initial treatment of a concussion. Perhaps a coach or doctor will move a finger in front of the patient’s eyes to see how they track movement, but this cursory examination does not get to the deeper repercussions of the injury.
It is interesting to note how eyesight has evolved. The vision system used to be more about looking far afield for what could be hunted and eaten – and what could hunt and eat us. These days, people are spending more time with their gazes fixed on their computer or TV screens or cell phones. There are certain physical dynamics to this everyday phenomenon. There is a lens inside the eye that flexes and focuses, so when we look at things up close, that lens has to work extra hard.
It may surprise you to learn eye-
What happened the last time you went on the Mad Tea Party ride at DisneyWorld? Did you enjoy yourself initially, but as the ride went on, did you start to feel sick and disoriented? When you closed your eyes, however, you probably felt much better. And you were immensely glad when the ride ended and you could get your bearings again.
Lazy eye is a term that is often used for three different conditions. One of those conditions is ptosis, which is a droopy upper eyelid that occurs after someone suffers nerve damage. If one eye does not see as well as the other, this is called amblyopia. Most commonly, the term lazy eye is for strabismus, when the eye either turns in (esotropia) or out (exotropia). If one eye turns up, this is called hypertropia. This condition is rare.
Is your child having problems in school? Do you frequently receive notes from his or her teacher about misbehavior or attention problems? It may surprise you to realize the child’s difficulties are the result of vision-
There’s more to seeing than meets the eye. Vision involves our eyes, brain and body. You cannot make an eye movement without sending a message to the body and vice versa. Performance optometry focuses on maximizing not just what you see but how well you can perform activities of daily living – driving a car, reading a book, hitting a ball. Vision is also essential to balance. It is a matter of how your sensory input works together, a process called sensory integration.
When you were first diagnosed with nearsightedness (myopia), did you resign yourself to wearing eyeglasses for the rest of your life, thinking nothing else could be done to improve your eyesight? Many innovations have been made in the treatment of myopia over the years. Most people are familiar with LASIK or refractive surgery, but a viable alternative you may not have heard of is orthokeratology.
Myopia (nearsightedness) is reaching epidemic proportions in the United States. About 42 percent of people in this country who are ages 12 to 54 years are myopic. Myopia occurs when the eyeball is too long from front to back or the cornea, the clear front cover of the eye, is curved. The anterior chamber of the eye is filled with aqueous fluid and the bulk of the eye is filled with vitreous humor. When the lens focuses, it’s like sitting on a basketball.
Presbyopia is a natural consequence of aging. In Greek, the word means “old eye.” Presbyopia usually first manifests when you are in your 40s. You may notice it’s getting harder to see things close up, but you can see things that are far away without any problem. You may have to hold reading material at arm’s length because it looks blurry when you try to read at a normal distance. Doing close work may cause headaches or fatigue. You may find you need more light to read or work by, and you may….

Behavioral optometry starts with the concept that vision is learned. When we’re born, we don’t know how to use our arms, legs and hands. We also don’t know how to use our eyes. We have to learn how to integrate them with the rest of our body. The brain must process what the eyes are seeing, and then it has to integrate that information with the other senses. From a behavioral standpoint, seeing requires a more holistic approach, getting all the senses to work together. Vision is movement: We learn how to use our eyes through moving our bodies. Our eyes control our movement through space. You can’t make an eye movement without sending a message to your body, and you can’t make a body movement with-
We know 70 percent of the input to the brain comes from the visual sense. From a developmental standpoint, the eyes initially are just simply watching, tracking and following the hands. Later, as we continue climbing the developmental ladder, the eyes begin directing the hands, telling them where to go. Visual input helps us attain fine motor skills as our eyes guide our fingers to do such tasks as threading a needle or holding a pen and writing. The eyes working together as a team allows us to judge space and distance. Changing input results in changing output.
While the term “hand-
to lead first, but when we’re learning how to do this, we start out watching hand movements. The first year of life is more about taste and smell. The next two years are more about touch and feel. By the time we’re three years old, vision starts to become our dominant sense. By using our hands and eyes together, we discover we can “touch” and explore the world with our eyes. We don’t have to physically grab items to determine what they are.
If you don’t learn proper visual skills early in your life, your eyes and brain will often devise shortcuts. Your brain has to use the visual information from both eyes. If the two eye views cannot be matched up, the brain will be forced to make a choice. It will reject all or part of the information from one eye. It may ignore, suppress or turn off visual information it cannot use. You can retrain the brain and teach it how to see properly and optimally. From a behavioral and developmental vision standpoint, this means re-
