DIY Eye Test.

I was looking for a belt in the top of my wardrobe and found my tea-towel collection.
I have no idea why I have a tea-towel collection or why I should choose to display it in my wardrobe.
That's by the by.
What is interesting is that one of the tea-towels in my collection is an eye test chart.
Fortunately it's a 'proper' eye test chart rather than one of those "amusing" charts that always leave one doubled up with mirth.

I badgered my assistant into holding up the tea-towel at what seemed like a reasonable distance:

Covering up my right eye I found I could, with some difficulty, read down to the first two letters of the third line.
I think that's an improvement.
