A growing number of people across the world are living with visual impairment, with one in every seven individuals affected, a top eye expert has warned.
Professor Chimdi Chuka-Okosa, a professor of ophthalmology at the University of Nigeria, Nsukka, made this known during the 2025 World Sight Day event at the Institute of Eye Health and Visual Sciences Research (IEHVSR), David Umahi Federal University of Health Sciences (DUFUHS), Uburu, Ebonyi State.
Speaking on the theme “Love Your Eyes,” Prof. Okosa said vision loss is a global health concern that demands urgent attention.
She urged Nigerians to take preventive steps, including regular eye check-ups, to avoid conditions that can lead to irreversible blindness.
“Good vision is not just about comfort; it is essential for personal safety, academic success, and economic productivity.
"Many people wait until it’s too late. Early detection through regular eye screening is the best defense," she said.
Prof. Okosa identified the leading causes of visual impairment as refractive errors, glaucoma, cataracts, diabetes, and sedentary lifestyles.
She also warned against harmful practices such as using breast milk or unverified prescriptions to treat eye problems.
She emphasized the need for public awareness, a healthy diet, and physical activity as critical factors in preventing vision problems.
Also speaking at the event, Dr. Kiran Ekochin, a Consultant Pathologist, highlighted the role of pathology in the early diagnosis and management of Neglected Tropical Diseases (NTDs) that can lead to blindness.
He noted that the World Health Organization (WHO) recognizes 21 NTDs, with a goal to eliminate many of them by 2030.
In another lecture, Dr. Jennifer Obani from the Department of Optometry at DUFUHS stressed the importance of early eye care in children, explaining that visual development continues until around age five.
“We recommend pediatric eye examinations at birth, regular screening before school, and teacher training to help spot early vision problems,” Dr. Obani said.
Earlier, the Vice Chancellor of DUFUHS, Prof. Jesse Uneke represented by Dr. Richard Nnabu, revealed that the Institute has provided free eye treatment to over 2,400 patients since February 2025.
He said the centre was established to improve access to quality eye care, especially for rural and underserved communities.
“This initiative has brought hope to people who otherwise could not afford eye care. The turnout continues to grow,” he stated.
He urged all and sundry to protect your vision by getting their eyes checked regularly.
As part of activities to mark World Sight Day, participants were offered free eye screenings, treatment, and awareness materials aimed at promoting better eye health.
