What is a Neuro-Optometrist? Vision Rehabilitation therapy helps improve the efficiency of the visual skills (eye control, eye focusing or accommodation, and eye teaming or vergence), and assist in the integration of vision with other sensory systems such as vestibular (ears) and proprioception (body) for balance and orientation.

Visual Skills for Driving
Although in many states, visual acuity and visual field are the only screening tests performed when obtaining a driver’s license, there are many functional visual skills for driving that are important. Research evaluating driving often uses physical measures of driving behavior (e.g. speed, braking, latency, scanning behavior, lane positioning). Research shows in particular that cognitive… Continue reading Visual Skills for Driving
Why Vision Screenings Are Not Enough
Vision screenings are not meant to be a comprehensive eye exam. Many just check to see if you can read a certain letter size at a certain distance then grant you the PASS and tell you that your vision is fine. But vision is so much more than sight… Vision guides movement whether it is… Continue reading Why Vision Screenings Are Not Enough
Beyond 20/20: What Is Normal Vision?
Everyone with what we term as “normal vision”, associates vision in terms of how good we can see and read. 20/20 is what most people think is normal or good vision; however, vision is more than being able to read letters and words. Vision is how we perceive things in our surroundings and space, it… Continue reading Beyond 20/20: What Is Normal Vision?
Vision and Balance
How does vision and balance relate? In this clinic, we get frequent referrals for patients who are suffering from dizziness and are often surprised that vision contributes a major part to their symptom of disorientation, falling, or lightheadedness. The Vestibular System Every part of the body is a different organ system: eyes, ears, skin, stomach,… Continue reading Vision and Balance

Visual Perception: The Visual Challenges of Reading – Part 2
Visual perception skills, such as spatial relations and figure-ground, are a necessary foundation for reading. On the most basic level, one must be able to differentiate words, letters, and punctuation marks. Developmental research has demonstrated that first grade students’ failures in visual perception directly affects their reading and writing skills. In contrast those with strong… Continue reading Visual Perception: The Visual Challenges of Reading – Part 2
The Visual Challenges of Reading – Part 1
Reading is an incredibly complex skill. Comprehension of written material is a result of coordinated eye movements, recognition of letter, numbers, or forms, and memory retrieval of existing facts, logic, vocabulary, and much more. Eye movements important for reading include: Fixation – The ability to keep the visual image still despite body and head movements. Our… Continue reading The Visual Challenges of Reading – Part 1
Vision Impairment and Falls Prevention
According to CDC, over one million people aged 65 or older fall each year. Less than half will report these falls to their doctors. Falling risk doubles after an incident of a single fall. Those with vision impairments are twice as likely to fall as those without vision problems. Types of Vision Problems Vision problems… Continue reading Vision Impairment and Falls Prevention
Ocular Albinism
About a month ago, Dr. Ho taught a cow eyeball dissection to a grade 7 science glass. Many of the students noted the excess dark pigment which rubbed off many of the structures within the eye which naturally led to some discussion of albinism. Albinism is a condition that reduces the amount of melanin pigment… Continue reading Ocular Albinism
