I apologize for how delayed my reply is. The SkinSmart hypochlorous acid spray is designated as safe for use on the face, eyelids, and eyelashes by the US FDA. I found the brand when it was recommended by a board-certified dermatologist who has a YouTube channel, where she discussed how this product is useful in management of eczema. SkinSmart sells the same product, just with different labels to make it marketable for different types of consumers, and the label used on the bottle for this listing specifically mentions its FDA approval for use on the eyes. They are transparent in their listings that this is all the same product, just with different labels and listings to make sure all audiences that benefit from hypochlorus acid are reached.

The page you sent me doesn't go into any detail about what would be dangerous about miniscule amounts of sodium hypochlorite, and it's distinctly written by a manufacturer of a hypochlorous acid cleanser designated for the eyes. It's even disclosing their Amazon affiliation at the bottom, so it's not even reputable. In Review of Optometry, Dr. Paul Karpecki OD writes: "All HOCl formulations are safe regardless of the purity level. Without the sodium hypochlorite (NaOCl) balance, the equilibrium shifts and the pure products are unstable." Dr. Karpecki is one of the leading dry eye experts in the world, so I trust he is correct when he specifies that the bleach byproduct is small enough of a percentage that it only serves to stabilize the product.
