Understanding your vision

Short-sight

This is the most common vision problem. You can clearly see close-up objects such as a wrist watch. Distant objects are blurred and out of focus. You may have some astigmatism as well.

Long-sight

This is the opposite - distant objects like motorway signs are very clear, but nearby objects can be blurred and it's difficult to focus on close-up work for any time. You may also have astigmatism.

Astigmatism

This vision problem is often combined with short or long-sight.

Presbyopia (Reading glasses)

As you get older the eyes struggle to focus on close-up work - including reading.
