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.

. Arrests cross-border kingpin; recovers cocaine, heroin from iron safe seized at Rivers drug den

Operatives of the National Drug Law Enforcement Agency (NDLEA) have intercepted consignments of captagon, widely known as ‘Jihadi drug’ and millions of opioid pills worth over N6.2 billion at the Murtala Muhammed International Airport (MMIA), Ikeja Lagos.

The captagon shipment was seized at the Lagos airport on Saturday 22nd August 2026 following the arrest of a 49-year-old cross-border kingpin Akinbile Kazeem Aikins, who arrived from Accra Ghana aboard an African World Airlines flight.

A search of his carton of local bathing soap, popularly called “Ghana Soap,” led to the recovery of 47,200 pills of the illicit amphetamine drug worth over N1.5 billion concealed within blocks of soap. Captagon, which is notoriously dubbed the ‘Jihadi drug’ for its use in funding extremist activities in conflict zones, was first intercepted in Nigeria by NDLEA in September 2021 at the Apapa port in Lagos. After his arrest, Akinbile claimed he was meant to deliver the consignment in the North.

In another successful interdiction operation at the Lagos airport, no fewer than 3,900,030 tablets of Tramaking 225mg and Tapentadol 250mg, with a combined gross weight of 2,787.40 kilograms and more than N4.6 billion in street value, were recovered from four abandoned consignments at the import shed of the MMIA. Three of the consignments, comprising 900,000 tablets of Tramaking (815.40kg), arrived aboard RwandAir flights from Bangladesh, while a fourth, comprising 3,000,030 tablets of Tapentadol (1,972kg), arrived on Qatar Airways from Amsterdam.


The shipments, which had been placed under close watch after no one showed up to claim them, were formally retrieved after a joint examination by NDLEA officers, Customs and other stakeholders on Friday 28th August.
A 31-year-old US-returnee, Sowunmi David Oludotun was on 19th August arrested by NDLEA operatives at Ikate area of Lekki after he showed up to take delivery of 3.350 kilograms of Loud, a synthetic strain of cannabis imported from the United Kingdom.

Fireproof safe cracked open in Rivers drug den raid In Rivers state, NDLEA operatives have raided the notorious Abuja Down/Up area of Port Harcourt where they recovered a fireproof iron safe among other items. When the safe was cracked open with a welding machine on Tuesday 25th August, 237 grams of colorado; 316 grams of cocaine, and 10 grams of heroin were recovered from it.

Three suspects: Oyedele Daniel, 42; Taye Saliu, 36; and Kehinde Saliu, 36, were on Friday 28th August nabbed at Ipele-Idoani road, in Ondo state with a total of 728kg skunk recovered from their truck marked KRE 120 XB. Two other suspects: Uche Joseph, 35, and Godwin Umeh, 21, were arrested at Aponmu forest with 341kg of same substance on Wednesday 26th August.

In Delta state, over 176,000 pills of assorted opioids including tramadol, molly and others were recovered from two interdiction operations in parts of the state between Wednesday 26th and Friday 28th August.
With the same vigour, Commands and formations of the Agency across the country continued their War Against Drug Abuse (WADA) sensitization activities to schools, worship centres, work places and communities among others in the past week. These include: WADA enlightenment lecture to students and staff of Markaz Littahfizul Quran Wal Islamiyyat, Dadin Kowa, Gombe; Zangina Islamiyyah Alasawa Kurna, Ungogo LGA, Kano; youths at the adolescent lifestyle programme organised by NNPCL in Benin city, Edo state; while the Ondo State Command of NDLEA paid a WADA advocacy visit to the State Governor, Dr. Lucky Aiyedatiwa, with the Taraba state command of the Agency paying a similar advocacy visit to the State Governor, Dr. Agbu Kefas, among others.

While commending the officers and men of MMIA, Ondo, and Delta Commands for the various successful operations, Chairman/Chief Executive Officer of NDLEA, Brig. Gen. Mohamed Buba Marwa (rtd) enjoined them and their colleagues across the country to continue with the ongoing balanced approach to the drug control efforts of the Agency.
He also directed them to sustain the momentum against drug traffickers who are desperate to explore every means, including concealment in everyday household items like soap, to move their illicit consignments.

Egyptian Queen’s 673-diamond Necklace Stolen From Museum

Austrian police are searching for two men who allegedly stole a 200-carat platinum necklace encrusted with 673 diamonds from a museum in Vienna.

The necklace, which was on loan to the Museum of Applied Arts (MAK), reportedly once belonged to Queen Nazli of Egypt. Police released images of the suspects captured by security cameras during the theft and appealed to members of the public for information that could help identify or locate them.

The two men reportedly entered the museum after buying tickets to the exhibition. During opening hours on Thursday afternoon, they allegedly smashed a glass display case with a hammer before taking the necklace and fleeing the scene. In an appeal for information, police said: “The perpetrators fled with the jewellery in an unknown direction.”

Officers searched parts of central Vienna and deployed a police tracking dog as they attempted to trace the suspects. Austrian newspaper Kronen reported that investigators believe the theft may have been carried out as a “contract job” for a criminal gang.

The stolen necklace was part of an exhibition that had been on display at the MAK since June. The exhibition featured more than 300 works associated with French luxury jewellery house Van Cleef & Arpels. No one was injured during the incident, although several visitors were reportedly present in the exhibition room when the theft occurred.

Museum documentation states that the necklace once belonged to Queen Consort Nazli of Egypt.

She reportedly wore the piece during the 1939 wedding of her daughter, Princess Fawzia, to Iran’s then Crown Prince Mohammad Reza Pahlavi, who later became shah. The necklace was sold by Sotheby’s in New York in 2015 for $4.3 million.

The MAK said the exhibition brought together about 200 “unique and rarely seen objects” from its own collection and pieces from the heritage collection of Van Cleef & Arpels, covering about 120 years of the jewellery house’s history.

Following the theft, a guided tour scheduled for Friday afternoon was cancelled, while the exhibition was temporarily closed.

The exhibition had been scheduled to run until September 27. The theft comes amid a series of high-profile robberies targeting European museums and cultural institutions.

In Spain on Thursday, thieves reportedly raided the Treasure of Villena, a collection of Bronze Age gold artefacts regarded as one of Europe’s most important prehistoric hoards.

Earlier this month, four significant works by 15th-century Renaissance painter Antonello da Messina were stolen from a museum in the Sicilian city of Messina.

Italian police also recently recovered three paintings by Paul Cézanne, Pierre-Auguste Renoir and Henri Matisse that had been stolen from a private museum near Parma. A recent Europol report warned that museum robberies in Europe are becoming increasingly violent, with criminals using weapons and heavy tools, including sledgehammers, axes and explosives, to target valuable cultural objects.
