Focus Daily Contact Lens

Updated and revised, the fourth edition of this reader-friendly reference presents straightforward guidelines for proper contact lens fitting. Covering today's full range of contact lens types, it also explores how to manage some of the major complications of contact lens wear. Devoid of extraneous optical theory, it focuses on the "hands-on" information that readers need to know in order to provide complete well-eye care.

Focus free lens - A focus free lens is a photographic lens whose focal point is fixed at its hyperfocal distance. Rather than having a method of determining the correct focusing distance and setting the lens to that focal point, a focus free lens relies on depth of field to produce acceptably sharp images.

Contact lens - Contact lenses (also known simply as "contacts") are lens placed on the cornea of the eye usually, but not always for corrective purposes. They serve the purpose of conventional glasses, but are very light and convenient, sitting directly on the eye.

Short Back Focus - "Short back focus": the distance between the rearmost optical surface of the lens and the film (or in this case the digital sensor) is shorter than that of a normal Canon EF series lens. A shorter back focus does have some advantages when designing wide-angle lenses, but there's a limit to how short it can be in an SLR lens since it can't be so short that the SLR mirror hits it when it flips up.

Principal focus - As the lens is transparent light can pass through it in both directions.As a result, there are two principal foci at equal distance from the optical centre of the lens, provided the medium on either side of the lens is the same.
