Single Vision lenses are lenses with one prescriptive power only. Depending on your eyesight requirements, they may be for short sight, long sight or astigmatism. Also, depending on the strength you may have to wear them all the time or only for detail.

Essilor single vision branded lenses are optimised to protect, enhance and correct vision. They correct short sight, long sight and astigmatism.

Bifocal lenses are prescribed for Distance vision and Near vision, usually as you get older. The Distance prescription is in the top part of the lens and the Near prescription is in the bottom part of the lens. There is a separating line between the two vision areas.

Office Lenses are designed for those who need reading glasses but also need more depth of focus. They are ideal for working at a computer or in an office environment. Office lenses have very large intermediate and reading areas with minimal distortion.

With decades of experience in ocular optics, these branded lenses are optimised for the most comfortable vision at intermediate and close distance, unlike single vision lenses which have a much more fixed depth of focus.

As the name suggests, these lenses have varying power over the depth of the lens. The top section is distance vision dropping to intermediate and then reading area towards the bottom of the lens. First timers to varifocals may take a little time to adjust to the head and eye movement required.
