Jackie Tan's editorial has described how many more pre-presbyopes wear contact lenses than presbyopes. As presbyopes (over the age of 45) are the fastest growing of the population we are faced with the challenge of providing these patients with adequate vision correction in a contact lens form.

While soft and rigid lens bifocals can be used, their limitations are obvious and of course there are no simultaneous soft lens bifocals that are made with Silicone Hydrogel lenses. We are all hopeful of that eventuating, with better designs and ultimately a translating silicone hydrogel contact lens.

However, until that time, if you are concerned about corneal response, especially in hyperopic presbyopes as has been clearly elucidated by Tan and Hines, then monovision is the answer.
