It means every second seat will be unoccupied.
Omniplex Cinemas is introducing 'in-cinema seat separation' to encourage effective social distancing in an effort to slow the transmission of coronavirus.
It means Ireland's largest cinema chain will be leaving every second seat empty at all screenings starting tonight.
Other measures include self-scanning of tickets, increased cleaning regimes and hand sanitising stations in every cinema foyer.
In-Cinema Seat Separation is the cornerstone of the plan, whereby every second cinema seat will be unoccupied in a checkerboard pattern.
Mark Anderson, Director of Omniplex Cinemas said: "In-Cinema Seat Separation will give 1m separation between each guest, as recommended by the World Health Organisation (WHO) for social distancing. By reducing our capacity by 50% we hope to give cinemagoers peace of mind when attending the movies."
