There are far fewer low-budget options in Montego Bay compared to nearby Negril, so this is mostly a mid-range area for the Caribbean, with a few really high-end places sprinkled in. The all-inclusive resorts in Montego Bay are excellent value, especially when packaged with a flight.
Instead of providing just two lens powers like bifocals (or three, like trifocals), progressive lenses are true multifocal lenses that provide a smooth, seamless progression of many lens powers for clear vision across the room, up close and at all distances in between.
A zoom lens is a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed focal length (FFL) lens (see prime lens).A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes.A lens that loses focus during zooming is more properly called a varifocal lens.enses in the latter group of zoom lenses, sometimes referred to as normal zooms, have displaced the fixed focal length lens as the popular one-lens selection on many contemporary cameras. The markings on these lenses usually say W and T for Wide and Telephoto.
