Accessibility – Main menu discernible names

Pagespeed Insights is reporting the following accessibility issue:

“Links do not have a discernible name – Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users.”

This relates to the main menu elements. Please provide a fix for this.
