Vision Impairment Testing: What It Is and Its Types

Vision impairment testing helps improve quality of life for anyone living with vision loss or low vision. Students and young adults with visual impairments often benefit from classroom accommodations that give them access to the highly visual world of learning.

While some adjustments can be as simple as sitting closer to the board, many students with low vision need tools such as reading glasses or bifocal lenses to magnify printed materials used in class.

In addition, people of all ages with reduced vision benefit from working directly with a low vision optometrist who can evaluate them for specialized tools and devices to enhance their visual access for specific tasks.

These devices may include a handheld magnifier for reading, or an electronic magnifier for distance viewing as well as near reading and writing. Modern assistive technology often integrates mainstream tools like Google Classroom with specialized tablet-based magnifiers, allowing students to use the same school apps and resources as their classmates.

Scheduling regular eye exams and vision impairment testing for yourself or your child is an important part of maintaining a healthy, active lifestyle. For people with low vision, reading, writing, recognizing faces, watching TV, and even driving may become possible with the right specialized tools and devices.

Depending on the results of the exam, your eye care professional may recommend prescription low vision glasses or a variety of low vision aids and devices to help you maintain your hobbies and daily activities. But what exactly is the difference between a routine eye exam and a low vision evaluation?

Types of Eye Examinations

When we hear the term “eye exam,” most of us think of the routine eye checks we have with an optometrist or possibly a series of tests with an ophthalmologist.

These routine exams are important even if we don’t wear glasses or contact lenses. An eye exam can reveal a great deal about our overall health. In general, children are advised to have a comprehensive eye exam once a year, and adults every two years.

Your child’s eye doctor or optometrist may recommend more frequent visits depending on your child’s eye condition and medical history. During these visits, the doctor will assess the health of your (or your child’s) eyes and review the current vision prescription, if there is one.

What Is a Low Vision Evaluation?

A low vision evaluation focuses on functional vision and on helping people achieve the highest possible level of visual function and independence in specific tasks. Low vision specialists work with patients to understand their goals—whether those goals are related to classroom needs, work requirements, independent living, or hobbies and personal interests.

Low Vision Examinations

A low vision examination includes a detailed functional history and a thorough assessment of the current glasses prescription. Once this is completed, the doctor helps determine which devices or strategies will be most beneficial for the patient. Devices that may be recommended in a low vision exam include, but are not limited to:

– High-powered reading glasses  

– Handheld magnifiers  

– Stand magnifiers  

– Electronic video magnifiers (CCTV systems)  

– Telescope systems for distance viewing  

– Specialized lighting and contrast-enhancing tools  

– Apps and software for screen magnification and text-to-speech  

In addition, low vision clinics educate patients about community resources, mobility training, and how to access transportation. Many people who seek low vision services are affected by age-related eye diseases such as macular degeneration, glaucoma, and diabetic eye complications. However, low vision clinics also serve younger patients with a wide range of visual needs.

Each eye condition affects vision in a unique way and may limit a person’s ability to recognize faces, read small print, walk safely, or drive. For these reasons, low vision examinations are highly individualized and tailored to each patient’s specific needs and goals.

Low vision evaluations are especially important as students prepare to transition to college, employment, and independent community living after high school. Low vision tools enable young people with reduced vision to access work, education, and society more independently.
