I’m interested in the eco size safety film and it says “safe for visual solar observation (with additional optics). What does with additional optics mean? Is there another filter that should be used with this film?

With additional optics means, with a telescope, a binocular or similar. UV/IR cut filter gives additional safety even if the film blocks these dangerous wavelength very good in combination with additonal optics like telescope or binocular.
