World Blindness Awareness Month Spotlights the Need for Early Intervention Programs

Throughout October, World Blindness Awareness Month serves as a powerful reminder of the importance of eye health and early detection of visual impairments. Blind Children’s Center (BCC) is using this month to not only raise awareness, but also emphasize how early childhood screenings can greatly shape a child’s access to resources.

Vision plays a key role in learning and development, influencing how children explore, learn and interact with the world around them. Yet, many vision issues in infants and toddlers go unnoticed without proper screening. Detecting visual impairments early allows families to shape their child’s educational journey by building essential learning skills right from the start.

“Early detection opens the door to early education,” said BCC Vision Services Coordinator Brenda Perla. “Providing early intervention services ensures children with visual impairments have every opportunity to reach their fullest potential.”

Blindness exists on a spectrum, ranging from low vision to total blindness. “Legal blindness” is defined as vision of 20/200 or worse in the better eye, meaning a person sees at 20 feet what someone who is sighted sees at 200 feet, even when using corrective lenses. It also includes individuals whose field of vision is restricted to 20 degrees or less, often resulting in tunnel vision. “Blindness” can describe complete vision loss or unreliable vision that requires the use of braille as a primary reading and writing medium. “Low vision,” on the other hand, refers to best-corrected vision of 20/70 or worse. Most students with visual impairments fall within this category and benefit from using residual vision aided by optical tools and adaptive strategies.

BCC observes several common diagnoses among students. The current leading cause of childhood blindness and low vision is Cerebral/Cortical Visual Impairment (CVI), a brain-based condition caused by damage to the visual pathways or processing areas. Children with CVI have difficulty focusing visually or recognizing people and objects. BCC also frequently sees Retinopathy of Prematurity (ROP), which affects premature babies or those weighing less than three pounds at birth. The severity of ROP can vary from mild cases that resolve without treatment to severe cases that result in permanent vision loss. Other causes of blindness include congenital conditions such as Childhood Glaucoma, Albinism, Aniridia and Anophthalmia.

While the causes and severity of vision loss vary widely, experts agree that early childhood education and intervention are essential for helping children with visual impairments reach developmental milestones. The first three years of life, when neural pathways for vision and learning are forming rapidly, are a critical period for brain development. Without early intervention, children with blindness or visual impairments may experience developmental delays of up to two years compared to their peers. Regular screenings help identify areas of need and connect families with services that support healthy development, from mobility training to braille instruction.

Research continues to highlight the connection between vision and learning. A 2015 study found that preschoolers with untreated astigmatism demonstrated lower academic readiness across multiple developmental and education domains. In 2018, researchers reported that early intervention for babies and children with visual impairments improved developmental outcomes and a 2022 study found additional benefits for behavior and family dynamics.

“At BCC, we understand that vision loss affects far more than sight — it shapes how a child learns, explores and connects with others,” said Chief Executive Officer Sarah Orth. “Our programs meet each child where they are, providing early education services to help them build confidence, independence and a lifelong love of learning.”

Beyond the classroom, BCC also encourages the public to adopt respectful communication practices when interacting with individuals who are blind or visually impaired. Always ask before offering assistance, identify yourself when entering the room and let the person know when you are leaving. Guide dogs, whose use is restricted to those 18 years and older with proper training, should not be distracted or petted while working. It is also not necessary to avoid words like “see” or “look,” and questions are always welcome.

Early screenings can make a lifetime of difference. With the right support, children with visual impairments can thrive academically and socially. For more information about visual impairments or early childhood screenings, connect with Brenda at BrendaP@BlindChildrensCenter.org.
