Symptoms of Vision Difficulties

When undetected, a vision problem can manifest in much the same ways as many, more popularly understood problems such as learning disorders, ADHD, and dyslexia. In turn, this may lead to misdiagnosis and subsequent frustration when treatment for that disorder is unsuccessful. With many children who suffer from a learning disorder, a vision problem may be the actual cause or may contribute to the problem.

Eyesight is a measure of how well a child can read letters at a given distance. Reading the “20 line” on an eye chart at 20 feet, for instance, translates into “20/20 eyesight.”

Vision is more complicated. It specifically refers to the health and abilities of the eyes themselves and how well they work. A child with good vision has strong eye movement control (including focusing and tracking), good eye teaming skills (how well the eyes work together as a team), good eye-hand coordination, strong abilities in recognizing symbols and images, and skills in connecting those visual images with auditory and tactile signals (sounds and feeling).

None of us know exactly how others see, and especially children do not often recognize when some aspect of their vision is not “normal.” As a result, children with vision problems will often attempt to compensate for a vision problem through behavioral changes. For example, a child with reduced eye teaming skills may cover one eye when reading, giving preference to the “good” eye.

Some patients perceive print as doubled and sometimes moving as shown above. As you cannot compare how you see to what others see, people do not always complain when they seen things this way.

Dr. Judson tests a child’s visual system as well as his or her eyesight and can help diagnose any problems that can be corrected with vision therapy or specially-designed lenses.

The following symptoms may indicate that YOU or your CHILD has a VISION PROBLEM.  If you observe one or more of these symptoms, we recommend a vision therapy consultation with Dr. Judson.

Vision in Infants & Preschoolers Treated By Our Vision Therapy Expert in Terre Haute

Vision problems can start at a very early age.  At a very early age, you can start noticing signs of vision problems in a child. Just like any preventative care, the sooner you spot difficulties, the easier it will be to improve your child’s vision as he/she begins to read and encounter other learning-related activities.

  • Appearance of the eyes: The eyes should have a normal appearance. When children are very young, their eyes may occasionally turn in toward their nose. This is a typical behavior. If you notice the condition persisting, you should speak with your optometrist.
  • Evidence of discomfort: It is difficult for a baby or a very young child to tell you they are experiencing discomfort. However, if a baby keeps his or her eyes closed during wakeful moments it may be a sign they’re experiencing some discomfort because it may feel better for them to keep their eyes closed.
  • Attention span: Visual attention, such as a baby’s recognition of his or her parents entering the room, is an indicator of early development of visual abilities.
  • Visual scanning: A child should be able to move his or her eyes quickly and accurately without excessive head movement. This ability is closely related to reading.
  • Orientation and localization: As a baby learns to hold his or her eyes on an object, he or she will begin to scan for specific details. This is part of their growing visual awareness of their surroundings. They are now becoming oriented to the world around them.
