People of African origin are at "significantly" higher risk of developing glaucoma, an avoidable condition that can cause sight loss, said the Royal National Institute of Blind People (RNIB) Scotland.
The event is being held during Black History month.
Free NHS eye tests are available to UK residents in Scotland.
The event, was arranged by Glasgow Caledonian University, in association with RNIB Scotland, to urge black Africans in Greater Glasgow and Clyde to attend eye examinations.
RNIB Scotland said people of African origin were more likely to suffer from glaucoma, which can lead to sight loss if not detected and treated early on, than those of white origin.
As well as discussing sight loss in people of black origin, the event is celebrating the work of leading US ophthalmologist Patricia Era Bath, one of the first African-Americans to gain prominence in her field.
RNIB Scotland equality officer Gozie Joe Adigwe, a Scot of African origin, said the charity was working with organisations that encounter people from Black African groups to support them with their eye health.
She said: "People [of black origin] are often unaware of the risks their ethnicity holds in sight loss."
In April, the "You Care, Eye Care" project, RNIB Scotland's project supporting Black Africans with visual impairment in Glasgow, secured funding until 2019.
Black History month is a celebration of African and Caribbean heritage observed annually in the UK since the late 1980s.
Free NHS eye tests have been available to UK residents in Scotland since 2006.

Mr Berlusconi's Forza Italia won 16 of 22 cities with the anti-immigration Northern League and another party.
The results were a setback for Matteo Renzi, the former centre-left prime minister seeking to return to power as head of the Democratic Party (PD).
"It could have gone better," he admitted in a social media post.
The PD currently heads a coalition led by Paolo Gentiloni, who took over after Mr Renzi lost a referendum on electoral reform in December 2016.
The biggest defeats for the PD were in party strongholds such as Genoa, La Spezia and L'Aquila. The centre-right also won in other provincial capitals including Monza, Piacenza and Pistoia.
Mr Berlusconi, 80, will now set his sights on the next general election, which is due in 2018 but may take place earlier.
Silvio Berlusconi may hope that 80 is the new 40. The gains made by his Forza Italia party in local elections allow him to claim the start of yet another political comeback.
"From these results the centre-right can set on a path to go back to ruling the country," he said in a statement.
But there is a major road-block in the way of his return for a fourth time as prime minister: he is currently banned from holding political office.
The ban, imposed following a 2013 conviction for tax fraud, doesn't expire until 2019. Unless he wins an early appeal at the European Court of Human Rights, Mr Berlusconi won't be able to run in Italy's 2018 general election.
Mr Berlusconi founded Forza Italia in 1993 and became prime minister the following year, with the Northern League as part of his coalition government.
Out of office in 1994, he then returned for a five-year period in 2001 and again in 2008 for three more years.
His political career has been overshadowed by his legal battles, which culminated in a community service sentence for tax fraud.
While Forza Italia's election advances were dramatic, commentators pointed to the low turnout of 46% and the first-past-the-post system in local elections. National polls are based on proportional representation.
The ex-prime minister said he would now seek a moderate, liberal coalition drawn from Christian roots. However, one of the parties in his alliance is the far-right Brothers of Italy.
Beppe Grillo's Five Star party fared poorly in the two-round vote, a year after it won control of Rome and Turin. Mr Grillo put a brave face on the result, pointing to victories in eight mayor races.
