Eye control starts in earnest from the time we are born. Some difficulties directing the eyes and generating complex binocular control may result in amblyopia, strabismus (turned eye), binocular dysfunction from vergence insufficiency and accommodation insufficiency.
Some problems resolve with sight correction in glasses and contact lenses. But some are variable problems recurring based on the amount of reading, or concentrated viewing with computer screens. These can occur within high precision sports such as target shooting and with fatigue in multisporting.
Attention, focus and directing the view are hard to sustain when the eyes are not correctly directed unconsciously to the desired location.
Binocular vision therapy works on these types of difficulties and generates a new understanding that we control the eyes globally before attending to the detail. This may be a short process to gain improvement for some but it will be a lifetime of visual awareness for others. It is not a surprise that eye control can be less accurate when we are tired and the view may blur or even double.
As the optometrist I enjoy working through these more difficult and thought provoking problems. My vision therapist and I guide people through individual programs to address these.
Visual fatigue and binocular dysfunction from screen and device use may resolve with glasses. However, resetting the binocular vision eye movements and focus may be necessary to fully reduce symptoms. It is also recommended to specifically improve habits or choices when viewing screens.
Our visual world is generated from a complex group of light, movement and expectation. When these do not align we experience discomfort and confusion. We look to resolve this.
