Ha line and UHC filters

Hi
I recently bought a UHC filter for visual observation; and noticed that it also transmits the H-alpha line as well as the H-beta and the 2 OIII lines. Will the transmission of the H-alpha make a difference as opposed to no H-alpha as far as visual goes, and will this affect the contrast?

Thanks in advance
