I recently hit that 40's age where short sight vision is now stuffed. I foresee a future of phone use frustration.

Amusingly, I use my phone to magnify the labels for food ingredients to make sure myself or my kid aren't eating problem foods.

It is amazing how many years people live after their 40's and so much stuff is now "hard" and yet no one will design for it. Even when they themselves will inevitably suffer from it one day.

Aging and death is an abstract concept to youth, for the most part. Source: I've been there.

There are some apps which you can use to scan labels with and it will tell you which allergens does it have.

I use Opera because it perfectly scales the text when I zoom in, as opposed to other browsers.
