Introduction

Hajiya Ramatu did not notice her vision was fading not at first.

It happened so gradually that she adapted without realising it. She stopped reading the Quran at night, blaming tiredness. She stopped recognising faces across the room, assuming people were standing further away.

By the time she finally visited a doctor, she had permanently lost most of the vision in her left eye.

The diagnosis was glaucoma and she had no idea she had it.

Her story is not unusual. Across Nigeria, millions of people are losing their sight to conditions that are preventable, treatable, or manageable when detected early.

How Common is Vision Loss in Nigeria?

Nigeria has one of the highest burdens of blindness and visual impairment in sub-Saharan Africa.

A large proportion of blindness in Nigeria is avoidable, meaning it could be prevented or treated if people had access to timely eye care.

In northern Nigeria, the problem is worsened by:

• Limited access to eye care specialists
• Low awareness of eye diseases
• Delayed hospital visits
• The belief that poor vision is simply “part of ageing”

In reality, many eye conditions can be treated successfully if action is taken early.

The Most Common Eye Conditions in Nigeria

1. Cataracts The Leading Cause of Blindness

A cataract is a clouding of the natural lens inside the eye.

This causes:

• Blurred vision
• Foggy or cloudy sight
• Difficulty seeing at night
• Increased glare from bright lights
• Colours appearing faded

Cataracts usually develop slowly and are most common after age 50.

Risk Factors

• Ageing
• Diabetes
• Smoking
• Long-term steroid use
• Excessive sunlight exposure
• Previous eye injury

Treatment

Cataracts are treatable with surgery, where the cloudy lens is replaced with a clear artificial lens.

Cataract surgery is one of the safest and most effective procedures in medicine.

2. Glaucoma The Silent Thief of Sight

Glaucoma damages the optic nerve the nerve that carries visual information from the eye to the brain.

In the most common form, damage develops slowly without pain or obvious symptoms.

By the time many people notice vision loss, permanent damage has already occurred.

Glaucoma is one of the leading causes of irreversible blindness in Nigeria.

Symptoms

Early stages usually have no symptoms.

Later symptoms may include:

• Loss of side vision
• Tunnel vision
• Blurred vision
• Halos around lights

Risk Factors

• Family history
• Age over 40
• African ancestry
• Diabetes
• High eye pressure
• Severe short-sightedness

Treatment

Damage already caused by glaucoma usually cannot be reversed, but treatment can slow or stop further vision loss.

Treatment may include:

• Eye drops
• Laser treatment
• Surgery

Early detection through regular eye checks is critical.

3. Diabetic Retinopathy

Diabetic retinopathy occurs when high blood sugar damages blood vessels in the retina.

It is becoming increasingly common in Nigeria because of rising diabetes rates.

Symptoms

• Floaters
• Blurred vision
• Dark spots in vision
• Difficulty seeing colours
• Vision loss

Prevention

The best protection is:

• Good blood sugar control
• Blood pressure control
• Regular eye examinations

Every diabetic should have regular eye checks, even if vision seems normal.

4. Trachoma Infectious Blindness

Trachoma is a bacterial eye infection that remains a problem in some rural parts of northern Nigeria.

Repeated infections scar the eyelids and eventually damage the cornea.

Symptoms

• Redness
• Eye discharge
• Light sensitivity
• Swollen eyelids
• Inward-turning eyelashes in advanced disease

Prevention

• Face washing
• Clean water
• Better sanitation
• Early antibiotic treatment

5. Refractive Errors Common but Easily Corrected

These include:

• Short-sightedness
• Long-sightedness
• Astigmatism

These conditions prevent light from focusing correctly in the eye.

Symptoms

• Blurred vision
• Eye strain
• Headaches
• Squinting

Treatment

Prescription glasses or contact lenses after a proper eye examination.

Avoid buying random glasses from markets without professional testing.

Warning Signs That Need Urgent Attention

Go to a hospital or eye clinic immediately if you experience:

• Sudden vision loss
• Flashes of light or sudden floaters
• Severe eye pain
• Red eye with vision loss
• Eye injury
• Sudden double vision

These can be emergencies that threaten permanent vision loss.

How to Protect Your Eyes

Wear UV-Protective Sunglasses

Sunlight exposure can contribute to cataracts and other eye damage. Choose sunglasses with proper UV protection when possible.

Eat Eye-Healthy Foods

Good choices include:

• Green leafy vegetables
• Sweet potatoes
• Eggs
• Fish
• Carrots

Green leafy vegetables and fish are especially helpful for long-term eye health. Carrots and other vitamin A-rich foods are also important, particularly for preventing vitamin A deficiency.

Protect Your Eyes at Work

Anyone exposed to:

• Dust
• Chemicals
• Metal
• Machinery

should wear protective eyewear.

Reduce Digital Eye Strain

Taking regular breaks from screen use may help reduce eye strain.

A simple method is to look away from your screen regularly and focus on something far away. The popular 20-20-20 rule may help some people, although the exact rule has limited scientific evidence.

Manage Diabetes Carefully

Good blood sugar control is one of the strongest protections against diabetic eye disease.

Avoid Rubbing the Eyes

Rubbing may spread infection, irritate the eye surface, and worsen some eye conditions.

Get Regular Eye Examinations

As a simple guide:

• Adults under 40 with no symptoms can check every few years
• Adults over 40 should check more regularly
• Adults over 50 should consider eye checks every 1–2 years
• Diabetics should have regular eye examinations, usually every year
• People with glaucoma risk factors should follow their eye doctor’s advice

Vision problems can affect school performance and learning.
