eyesight

It’s painfully ironic that Oliphant could look at the world so hard, for so long, and be repaid with the slow loss of his eyesight, as Banowsky finds toward the end of the film.

The move comes after an inquest into four deaths caused by drivers with failing eyesight saw a coroner call the UK's licensing system the "laxest in Europe".

At the age of two, Toby Addison was diagnosed with early onset rod cone dystrophy and retinitis pigmentosa, which meant his eyesight would slowly deteriorate.

The couple said in a statement that she was "very conscious of road safety and competent at crossing roads, knowing which way to look, and had perfect eyesight".

In contrast, auto-focus lenses promise to adjust part or all of the lens spontaneously, and even accommodate the wearer's changing eyesight over time.
