People who are suffering from sight deterioration related to ageing have been advised of the options available.
Writing for Canadian publication the Windsor Star, Dr Todd Wilbee explained that monovision contact lenses may be worn, meaning that a person would wear a reading lens in one eye and a distance lens in the other.
Bifocal contact lenses can also be used.
For those who do not wear contact lenses, reading glasses are an option, although some may find it inconvenient to keep taking them on and off.
As an alternative, bifocal lenses may be worn, either lined or unlined.
The second type is often thought to be more aesthetically attractive, as the line between the top and bottom viewing halves cannot be seen
