Please note, this low cost filter is not "antireflection" coated.

I made a mistake of learning how to read the wavelength chart after buying the filter.
this filter is dedicated to remove a certain wavelength around 580mm and 490nm, which means that this filter can help you if your city is using Hight Pressure Sodium lights. If, on the other hand, you city uses White LED lights, that peak around 450nm, then this filter will not do the job.
