SILENT VISION THIEVES: Experts warn against everyday habits damaging Nigerian eyes
Leading eye care specialists have issued a stark warning to the public regarding common, everyday habits that significantly increase the risk of eye damage, severe infections, and permanent vision loss.
Ophthalmologists and optometrists are urging Nigerians to pay closer attention to their ocular health amid a rising tide of environmental hazards and skyrocketing screen time. Beyond vision, experts also revealed that a routine eye check could save your life by detecting hidden killers like hypertension, diabetes, and brain tumors before symptoms manifest.
Many people are unaware that the eyes can suffer from sunburn just like the skin. Medically known as photokeratitis, this condition is triggered by prolonged, unprotected exposure to intense ultraviolet (UV) radiation.
Speaking on the condition, prominent Ophthalmologist Dr. Emmanuel Utomi explained that photokeratitis causes redness, severe pain, and extreme sensitivity to light.

“It often feels as though the cornea has been scratched,” Dr. Utomi noted, adding that it is frequently seen in individuals who spend long hours outdoors or at the beach without adequate eye protection.
While photokeratitis typically heals within a few days, experts warn that repeated UV exposure without protective eyewear drastically accelerates the development of cataracts and other long-term vision impairments.
Specialists strongly advise wearing sunglasses or protective goggles that block 100% of both UVA and UVB rays whenever outdoors.
The blind spots of contact lens wearers
Contact lens users are facing severe warnings against two major habits: swimming and sleeping in their lenses.
According to Dr. Chinedu Anthony Okeke, Medical Director and Senior Consultant Ophthalmic Surgeon at RightSight Specialist Eye Centre, water sources—including swimming pools, lakes, and oceans—are breeding grounds for bacteria, parasites, and harmful chemicals. Contact lenses trap these microorganisms against the eye, creating a perfect environment for devastating infections to thrive.
Similarly, Optometrist Dr. Chukwuemeka Achimnole warned that sleeping in lenses drastically increases corneal injuries. During sleep, natural tear production decreases and oxygen flow to the cornea is restricted. This causes the lens to tighten and adhere to the eye’s surface, often tearing or damaging the cornea upon removal.
The Digital Strain: How screens are drying out our eyes
The specialists further linked the growing prevalence of dry eye disease to relentless screen exposure from smartphones, laptops, and television.
When staring at digital devices, our blink rate drops significantly, starving the eyes of the natural lubrication required to keep them healthy. To combat digital eye strain, the medical experts recommend adopting the “20-20-20 rule”:
Every 20 minutes, take a break.
Look at an object at least 20 feet away.
Hold your gaze for at least 20 seconds.
The use of preservative-free artificial tears can help maintain essential eye moisture.
A window to your overall health
Perhaps the most crucial revelation from the medical experts is that a comprehensive eye examination does far more than test your sight—it can save your life.
Because dilated eye exams allow doctors to directly observe the body’s blood vessels and nerves, they routinely serve as an early warning system for systemic health conditions, including diabetes and hypertension (high blood pressure), cardiovascular disease and high cholesterol, certain sexually transmitted infections (STIs) and neurological disorders and certain cancers.
Dr. Utomi recalled a striking case where a patient complained of nothing more than a simple difficulty in reading. A comprehensive eye examination revealed the underlying culprit: a brain tumor.
Medical experts are urging Nigerian adults to schedule regular, comprehensive eye examinations, even if they currently have perfect vision. Early detection remains the single most effective shield against preventable blindness and underlying, life-threatening diseases.
