When outputting certain content, it’s useful for it to retain the features of WordPress’ the_content() function. Namely, that paragraphs are automatically generated (wpautop), shortcodes are run, and oEmbed converts certain links to rich media (ex: Youtube video link becomes embedded video).
You could do this by wrapping your content in apply_filters( 'the_content', $my_field );, but some plugins use the 'the_content' filter to add their own functionality to the main post content. You might end up with sharing links or some other unwanted feature on your content.
I create my own filter, 'ea_the_content', to which I attach all the functions I want. I can then use apply_filters( 'ea_the_content', $my_field ) without worrying about another plugin using the filter.
