The Importance of Children’s Vision Screening by MaryAnn Ragone DeLambily

Why Early Vision Screening is Important

Eye Screening is intended to detect vision disorders that may lead to Amblyopia, also called lazy eye. Many vision disorders, if not detected and treated during the first years of life, can lead to permanent vision impairment, which neither glasses nor any other visual aid can address. 

Learning is Visual

Approximately 80% of all learning comes through the visual pathways. Any interruption or interference in the visual pathways can detain a child from performing to his maximum potential. If a child is not learning according to his potential or level, then this will cause a delay in the learning process and/or development causing difficulties and struggles as they progress in school.

According to the American Optometric Association (AOA), 25 percent of all children, or 1 in 4 students, have a vision problem significant enough to impact their learning.

Why Do We Need Early Vision Screening

We need early vision screening for children for prevention. We all know about the importance of preventative medicine. This is no different. From the ages of 0 thru 3 years of age, amblyopia prevention is critical. It is at this time of prevention that Amblyopia or other complications can be treated. After the age of 3 years old, prevention is still necessary, but as children get older, it gets more difficult to treat. 

Early vision screening identifies risk factors in children from early as 6 months of age through 6 year of age. The earlier risk factors are identified through screening, the earlier it can be treated. 

Possible Vision Problems

Vision problems can lead to a loss of sight, learning difficulties or delayed development.  Some visual disorders lead to a disability called Amblyopia which can cause monocular blindness. According to Prevent Blindness, it is estimated that two to three percent of the general population suffers from Amblyopia. An amblyopic child who was never treated becomes an amblyopia adult with lingering difficulty in learning, sports, and maybe even a job or career.

What is Amblyopia?

Amblyopia is also called lazy eye. It is a disorder of sight due to the eye and brain not working well together.  It results in decreased vision in an eye that otherwise typically appears normal.  It is the most common cause of decreased vision in a single eye among children and younger adults. 

Strabismus and significant refractive errors are considered risk factors for Amblyopia which include myopia, hyperopia, astigmatism, and anisometropia.  Refractive errors occur when parallel light rays are not brought to a sharp focus precisely on the retina, producing a blurred retinal image. 

Definition of Refractive Errors

* Nearsightedness (Myopia) – the cornea and lens bend (refract) incoming light rays so they focus precisely on the retina at the back of the eye resulting in blurred far vision.

* Farsightedness (Hyperopia) – In the farsighted eye, the light rays are refracted too far.  They meet behind the retina, resulting in blurred near vision.

* Astigmatism – In astigmatism, the curvature of the cornea is irregular, causing light rays to focus to more than one place so that a single clear image cannot be formed on the retina, resulting in blurred vision.

* Anisometropia – This means that the two eyes have a different refractive power (glasses prescription) so there is an unequal focus between the two eyes.

* Anisocoria – this means the pupil size is significantly different in size between each pupil. 

* Strabismus – There are different types of strabismus including esotropia where one or both eyes turn inward; Hypertropia when the visual axis of one eye is higher than the fellow fixating eye and Exotropia when one or both eyes turn outward. 

How Does Early Vision Screening help?

A vision screening may identify the need for a more comprehensive eye exam to be completed by an eye care professional. A screening can be done by lay people such as the Lions Clubs, medical and non-medical professionals, school nurses, pediatricians, and others. The intention of a screening is to identify, not diagnose, vision problems in the early treatable stages. It renders a result, if not passing, a referral to an eye care professional for further evaluation. 

Vision screening is important because it gives the opportunity to prevent, detect, and treat children that otherwise may be at risk of permanent and lifelong visual disability. A child may not even know their eyesight isn’t normal because it might be normal for them.  It is important to get these screenings done to find the problems that could be easily missed. 

The Best Time for Early Vision Screening is Now When it comes to young eyes, there is an important window of opportunity when certain vision conditions can be more easily corrected while children are still growing and developing. 

March is Save Your Vision Month – by MaryAnn Ragone DeLambily

Save your Vision month

One thing should be common to all: Good eye health is important at all stages in life and should be taken seriously before it’s too late. Unfortunately, for some, getting a routine eye screening or check-up is not thought of until they have a vision problem. Therefore, the American Optometric Association has recognized the month of March as Save Your Vision Month. But what does the “Save Your Vision Month” mean?

Save Your Vision Month is designed to help and educate the public on the importance of taking care of your eyes on a regular basis. This special day is designed to foster awareness and promoting good eye health.

But good eye health encompasses many different things and means different things to different people. Plusoptix supports the American Optometric Association in acknowledging Save Your Vision Month and providing state-of-the-art Vision Screening devices to enable Primary Healthcare Providers to detect vision disorders in children as early as possible.

Eye health and vision care is important at any age. Having 20/20 vision is the vision that most of us want because it means we have very good vision. Testing for good vision or 20/20 vision when children are young is especially important. It is during this time that we can prevent future problems if detection early on is successful. Let’s first start with asking, what is 20/20 vision about? 


The term 20/20 vision may mean different things to different people. For one, a phrase most of us are very familiar with is “hindsight is 20/20”, meaning: If you only had a better understanding of a situation, it might have turned out better or different. For others, a 2020 outlook could have meant a bright and perfect future.

Best practice: How to perform vision screenings amid COVID-19

Plusoptix device measures refraction through sneeze guard

It seems like many people avoid going to the doctor for well check visits amid the Covid-19 pandemic. But don’t forget that instrument-based vision screening is very important! 1 of 5 children has visual disorders which may lead to amblyopia, often referred to as “lazy eye,” if not treated early enough. Thus, we would like to answer the following question: How to perform vision screenings amid COVID-19?

Well, how to perform vision screenings amid COVID-19? A contact-free and safe way of vision screening amid COVID-19 is more important than ever before. Plusoptix devices can detect the most prevalent visual disorders within less than 1 second from 3.3ft (1m) distance – even through sneeze guards. The earlier visual disorders are being detected, the easier the development of amblyopia (lazy eye) can be avoided.

Vision screening programs need photoscreening devices that are reliable.

By Ryan Ham

As a member of the Athens, Ohio, area Lions Club, I have been involved in vision screening efforts for the past 4 years. Recently, we began looking for an updated device to use. We were looking to grow our outreach efforts to involve more kids. Knowing that other Ohio groups were fans of the Plusoptix vision screening devices, we decided to purchase four machines. Our district raised the needed money, and we received a matching grant from Lions International.

Value of photoscreening programs – by Matthew Doerr, MD

Photoscreening can help identify children who need vision correction.

By Matthew Doerr, MD

Children are often referred to my pediatric ophthalmology practice due to a failed photoscreening. Frequently, the device-based evaluation was performed at school or a pediatrician’s office. These programs use a photoscreener like the Plusoptix Vision Screener. I am an advocate for the use of these systems. Photoscreening can identify children who need glasses but are too young to read an eye chart. The devices are also useful for children who may be otherwise uncooperative.

Hearing is mandated in Arizona for school kids, but not vision.


I am the nursing supervisor for the Yavapai County Education Service Agency (YCESA) in Prescott, Arizona. As a needs-based organization, YCESA provides a variety of services to any interested local schools. Often, these are schools that cannot afford to hire full time staff. The services including nursing, counseling, physical and occupational therapy. The YCESA supports 28 schools in our rural, far-flung county.

Arizona mandates proof of a hearing test for school entry . No such requirement exists for vision. To emphasize the importance of vision screening, our team decided to write a grant. Grant’s goal was to create a screening program in the Prescott Unified School District. The program would ultilize our Plusoptix autorefractor. The school had been using traditional vision screenings methods, which are difficult for preschoolers to comply with. Even some kindergarteners can struggle with eye charts as well as children with special needs.

Connecting those in need with important services – by Hank Lunsford

Through coordinated community efforts, our program conducts vision screenings for hundreds of kids every year.


The annual Day 4 Hope, which partner’s schools with sponsoring churches, started more than a decade ago. In Sarasota, 38 nonprofit organizations contribute to these back-to-school events to benefit children in need. At the fairs, each child is given a backpack filled with school supplies, including gift certificates for school uniforms and shoes. Additionally, the children receive books and even free haircuts and hair styling. The events are meant for the entire family, where they can get sheriff identification and family portraits taken.
