Residential film works on several things at once. It reduces solar heat coming through the glass, filters ultraviolet light that contributes to fading, and cuts glare on screens and reading areas. Depending on the product, it can also provide daytime privacy without blocking daylight, or tidy up the appearance of mismatched glazing across a facade. Safety film adds another dimension by helping hold broken glass together after an impact, though it is not a guarantee against entry or injury. Which of these benefits you get, and how strongly, depends on the film chosen and the glazing it goes onto.
