The film sets out to show that everyday tasks are easier when you take good care of your eyesight.

We begin outside a typical inner-city tower block. A delivery man arrives with an extremely heavy and awkward parcel. His struggles are compounded by a broken elevator, forcing him to use the stairs.

Ten flights later, having successfully negotiated his way past various occupants of the building, he arrives at the door of a flat. Exhausted, he hands the lady an electronic device to sign. But she's confused; she wasn't expecting anything. She looks at the device and announces to the delivery driver that he's in the wrong tower block. She points to another equally high building - "Block 2" - some distance away.

A super on the screen reads 'Should've gone to Specsavers' - suggesting our short-sighted hero needs visit the well-known optician for an eye test.
