Hunger protest: ophthalmologists caution against prolonged exposure to tear gas

*Says, it may cause blindness

By Francesca Hangeior

Leading eye specialists have cautioned that prolonged exposure to tear gas could cause temporary blindness and other eye complications, which if left untreated could lead to permanent blindness.

They also noted that people without protective clothes and devices were at risk of cornea injuries and conjunctivitis when exposed to tear gas.

The ophthalmologists advised those exposed to tear gas to quickly rinse their eyes and affected body parts with water.

The experts’ warning and advice comes on the heels of the 10-day protest that began on August 1st and had been marred with security agents firing tear gas to disperse protesters.

Under the #Endbadgovernance and #Hungerprotests, several Nigerians in several states of the federation, have through placards and chants demonstrated their displeasure with the current economic hardship.

But the President, Bola Tinubu, in an address to the nation on Sunday, told protesters and the organisers to suspend any further protest and create room for dialogue.

Tear gas is a riot control agent mostly used by law enforcement agents that temporarily constrain people by irritating the eyes, mouth, throat, lungs, and skin.

According to the Centre for Disease Control and Prevention, long-lasting exposure or exposure to a large dose of tear gas may cause blindness, glaucoma and respiratory failure possibly resulting in death.

However, a professor of Ophthalmology at the University of Benin, Edo State, Afekhide Omoti, stated that prolonged exposure to tear gas in an enclosed environment could cause blindness.

He, however, noted that the risk of blindness was reduced if the tear gas was used in an open environment.

The Chairman of the National Eye Health Committee said, “In the normal circumstances where tear gas is used in an open environment, it will not cause blindness.

“However, if there is prolonged exposure in a closed environment, it is possible that tear gas can cause blindness,” he said.

The researcher on Glaucoma and Anterior Segment Disorders further noted that physical exertion, such as running after contact with tear gas, makes the affected persons more susceptible to severe symptoms.

Omoti said, “As far as blindness is concerned, large doses may cause temporary blindness.

However, in very unusual circumstances, and depending on the delivery system, more prolonged damage can occur.

Explosive systems, particularly those used in the military, may cause thermal, chemical, and physical damage due to the blast. If left untreated, it can cause permanent blindness. But this is not the usual type used by the anti-riot police.”

The researcher on Glaucoma and Anterior Segment Disorders further noted that tear gas might worsen the conditions of persons with corneal problems but had no effect on those with cataracts and glaucoma.

He added, “Depending on the specific chemical agent used in the tear gas and the mode of delivery, tear gas can cause a variety of eye defects which include mild features such as blepharospasm, conjunctivitis and superficial keratitis.

“More severe complications which are very unlikely include corneal stromal opacities, corneal neovascularisation, neurotrophic keratopathy, conjunctival necrosis, and pseudopterygium. These are all problems with the cornea and conjunctiva, the surface structures of the eye.

“Ordinarily, those with glaucoma should not be at higher risk of blindness from tear gas use. However, if the explosive variety is used, and as I said earlier, this is not the usual type used in our civilian crowd control, then the physical effects may increase the intraocular pressure and worsen the glaucoma or even theoretically cause blindness in terminal stages. But I must again reiterate that this is not likely.”

The ophthalmologist asserted that if these eye defects were untreated, it could cause possible complications, which could lead to blindness.

“Untreated, possible complications which will cause blindness, especially in explosive cases include corneal neovascularisation, stromal thinning, ulceration, infection and perforation. Others include secondary glaucoma, cataract formation, vitreous haemorrhage and traumatic optic neuropathy which are physical complications of the explosive which are not normally used in civilian crowd control,” Omoti said.

Also, the President of the Ophthalmological Society of Nigeria, Dr Abiola Oyeleye, stated that tear gas affects the eyes and skin of those it comes in contact with, noting that when inhaled, it affects the lining of the mouth, nose, chest, lungs and the respiratory system.

The ophthalmologist emphasised that direct exposure of tear gas to the eyes could damage the eye structures and lead to blindness.

The Medical Director of the Eye Doctors Group of Clinics, said, “So if we are specific now about the eyes, what it does, it irritates the eye, and anything that irritates the eye causes tears, and that’s where the name tear gas is from. So the eye sends a message to the brain that something is irritating me and the brain now sends a message to the tear glands saying something is irritating the eye, send tears to the eye, the tear glands now function and send tears to the eye, so it’s a response to whatever agent has caused it, that’s where the name tear gas comes from.

From Blackouts to Breakthroughs: Why West Africa’s Energy Story Is Far From Finished

For millions of people across West Africa, electricity remains a privilege rather than a guarantee. While cities grapple with frequent blackouts and ageing infrastructure, many rural communities still live beyond the reach of national grids, relying on candles, kerosene lamps and diesel generators to power their daily lives.

Yet a quiet energy revolution is unfolding across the region.
From Senegal to Ghana, Cabo Verde and Nigeria, solar mini-grids and off-grid renewable energy systems are gradually changing the story, bringing power to villages that have waited decades for electricity. The transformation is creating businesses, improving healthcare, supporting education and opening new economic opportunities.

But as promising projects emerge, a new challenge is becoming clear: generating electricity is no longer the biggest problem. Keeping pace with rising demand, financing expansion and building sustainable systems are proving to be the real test.

Access to electricity has long been one of West Africa’s greatest development challenges. According to the ECOWAS Centre for Renewable Energy and Energy Efficiency (ECREEE), millions of people in the region, particularly in rural areas, still lack reliable access to electricity despite significant progress over the past decade.

The ECOWAS Vision 2050 framework identifies energy access as a critical driver of industrialisation, regional integration and poverty reduction, recognising that economic growth cannot thrive without dependable power supply.

The situation reflects a wider African reality. While investment in renewable energy is increasing, expanding electricity access remains a major challenge because of population growth, financing gaps and ageing transmission infrastructure.

International agencies and reports by Reuters have repeatedly highlighted how frequent power shortages continue to slow industrial production, discourage investment and increase the cost of doing business across the region.

Against this backdrop, renewable energy has emerged as one of West Africa’s most practical solutions.

In Senegal’s Fatick Region, the rural community of Ndiob offers a glimpse of what is possible.

During a recent field mission, members of the ECOWAS Parliament’s Joint Committee on Energy and Mines, Infrastructure, Agriculture, Environment and Natural Resources travelled from Dakar to inspect a solar-powered mini-grid serving three villages.

Managed by Green Impact West Africa under the supervision of Senegal’s Rural Electrification Agency (ASER), the project uses a containerised solar plant equipped with photovoltaic panels and lithium-ion battery storage to supply homes, schools, health centres and small businesses.

The impact is visible everywhere, as street lights illuminate roads that were once dark after sunset. Health centres preserve medicines safely. Schools enjoy longer study hours, while artisans such as welders, tailors and carpenters have expanded their businesses because electricity is available throughout the day.

Women have found new opportunities through food preservation and small-scale processing, while young people are being employed as technicians responsible for maintaining the solar facilities.

For residents, electricity has become more than a public service; it has become an economic asset.

As local resident Mustafa Faye told visiting lawmakers, thst the village now resembles a growing town, attracting residents who work in Dakar but choose to live in Ndiob because of improved living conditions.

Ironically, the success of the Ndiob project has exposed one of renewable energy’s biggest challenges.

Demand is growing faster than supply, especially when more households now own refrigerators and electrical appliances, while businesses require greater power capacity than the original installation was designed to provide.

Residents complain of low voltage and irregular supply, making it impossible to operate high-energy equipment such as air conditioners and larger machinery.

But the problem is not peculiar to Senegal. Across West Africa, many mini-grid projects were initially designed as pilot schemes serving small populations. As communities expand and local economies improve, electricity consumption rises sharply, placing enormous pressure on existing infrastructure.

Battery storage remains another major constraint.
Solar energy is abundant throughout West Africa, but without sufficient storage capacity, electricity generated during the day cannot always meet evening demand when households and businesses consume the most power.

Operators also face high maintenance costs, logistical difficulties in reaching remote communities and the challenge of replacing specialised equipment.

The biggest obstacle may not be technology but investment. This is because renewable energy projects require significant upfront capital, while returns often take years to materialise. Rural communities with low incomes may also struggle to pay electricity bills consistently, especially during agricultural off-seasons.

This makes long-term sustainability difficult without continued support from governments, development finance institutions and private investors.

Recognising these challenges, lawmakers at the ECOWAS Parliament’s five-day delocalised meeting in Dakar adopted resolutions calling for accelerated deployment of decentralised renewable energy systems across the region.

The Parliament recommended stronger financing mechanisms, harmonised regulations, improved quality standards for renewable energy equipment and greater support for productive uses of electricity that generate income for rural communities.

The lawmakers also urged increased backing for ECREEE and renewed efforts to address financial challenges affecting the West African Power Pool (WAPP), the regional electricity integration project designed to enable cross-border power trading.

For many policymakers, sustainable rural electrification will depend on community ownership rather than government intervention alone.

Speaking after the field visit, ECOWAS Parliament Vice Chairman of the Committee on Infrastructure, Hon. Ahmed Munir, said renewable energy projects are already creating jobs and reducing poverty across rural communities.

According to Munir, lawmakers witnessed women producing and selling ice blocks, tailors expanding their businesses and young technicians maintaining solar installations.

“We saw prosperity, not just electricity,” he said.

Munir argued that communities should actively invest in renewable energy enterprises instead of waiting for governments or foreign investors to solve every problem.

His position reflects a growing consensus among energy experts that local participation increases project sustainability while creating stronger economic incentives for maintenance and expansion.

The experience in Ndiob demonstrates that electricity is not simply about switching on lights.

Reliable power supports cold storage for farmers, reduces post-harvest losses, improves healthcare delivery, strengthens education and creates opportunities for entrepreneurship.

Every additional connection has the potential to generate employment and stimulate local economies. The visit also exposed a broader reality confronting West Africa’s energy transition: solar panels alone will not solve the region’s electricity deficit.

Greater investment in battery storage, stronger transmission systems, local technical skills, supportive regulations and innovative financing models will all be required if renewable energy is to achieve its full potential.

West Africa possesses one of the world’s richest solar resources, but the challenge is no longer whether the region has enough sunshine.

The real question is whether governments, investors and communities can work together to transform that natural advantage into reliable electricity capable of powering homes, businesses and industries for generations to come.

If the lessons from Ndiob are any guide, the future is already taking shape. What remains is ensuring that the infrastructure grows as quickly as the ambitions of the people it serves.
