Vision impairment is a reduced ability to see that cannot be fully corrected with standard eyeglasses or contact lenses. Its causes are varied, ranging from refractive errors and age-related conditions to neurological injuries, and treatment approaches can target the eyes and the brain. Here’s more information on three neuro-optometric services for vision impairment concerns:
1. Specialized Lenses
Beyond standard prescriptions, specialized lenses aim to modify visual input to enhance visual functions. These can include prisms, which alter how light enters the eye to assist with alignment, or specific tints and coatings designed to manage light sensitivity. Task-specific prescriptions for activities like computer use or reading are also common tools.
Neuro-optometry services involve comprehensive assessments that evaluate how an individual’s visual system functions to verify the causes of vision impairment. They assess eye movements, visual processing, and binocular (two-eyed) coordination. Neuro-optometry care benefits individuals experiencing visual symptoms after a concussion or stroke, as well as those with binocular vision disorders or persistent visual discomfort.
How the Eyes Send Signals
The eyes capture light and convert it into electrical signals that travel to the brain via the optic nerve. This conversion process relies on precise muscular control for functions like focusing at various distances, turning the eye muscles, and shifting the gaze actively between different focal points. These mechanisms work together to gather clear, accurate visual information from the environment.
How the Brain Interprets Vision
Once visual signals reach the brain, it processes them to interpret depth, motion, color, and object recognition. The brain combines the images from both eyes into a single, three-dimensional view and directs visual attention. When there is a mismatch between the signals the eyes send and how the brain processes them, symptoms like eyestrain, headaches, or double vision may occur.
2. Vision Therapy
Personalized vision therapy is a structured program of activities designed to practice and reinforce specific visual skills, guided by a specialist. These programs are tailored to an individual’s needs following a comprehensive visual assessment. The goal of vision therapy exercises is to improve the efficiency and coordination of the visual system through targeted practice.
These programs often include exercises that support the connection between the brain and the eyes, but some programs also incorporate tasks for hand-eye coordination. Some vision therapy exercises focus on practicing and improving how the eyes operate together. Exercises may include activities that help improve eye focus abilities, and tracking activities help eye movements become smoother.
3. Balance Training
Because the visual system also provides information for maintaining balance, disruptions to vision can directly impact an individual’s stability. Balance training activities help the brain integrate information from these different sensory systems more effectively. Some modern treatments use computer programs and digital tools to guide these exercises and track performance parameters over time.

Multiple approaches exist for addressing vision issues, from specialized lenses and vision therapy to balance training. A neuro-optometrist can provide an individual evaluation to determine which treatment approach will benefit your needs. If you are experiencing visual difficulties, schedule an assessment for more personalized information.
