description	A spray device for delivering a liquid spray, having a spray length, through air to a target, in particular an eye, comprises a container for holding a liquid, means for pressurizing a quantity of said liquid to an elevated operating pressure, and comprises a nozzle member that comprises a nozzle plate with a plurality of nozzle orifices of substantially identical size, extending through said nozzle plate and communicating with said means to receive a quantity of pressurized liquid at said operating pressure. Said nozzle orifices discharge said liquid spray at an outlet surface of said nozzle member member over said spray length Their substantially identical size is between lower and upper limits (Dmin), (Dmax),wherein said lower limit is approximately:D⁢min≈1/10⁢L⁢λΔ⁢P/ρ,wherein said upper limit is approximately:Dmax≈1/10⁢2⁢L⁢λΔ⁢P/ρ.λ≈18 η/ρ, η=1,8.10−5 kg/ms, representing the viscosity of air and ρ representing a density of said liquid.
