Presyopia usually becomes apparent around the age of 40 and progresses from then on.

Passive 3D glasses are polarized glasses used for viewing 3D movies in theatres, as well with some 3D televisions, such as those offered by Vizio and LG. They differ from active glasses in that they are simple plastic lenses with polarized filters for each eye. They require a special TV screen with a polarizing filter and display elements. They do not require batteries and are very light weight. Active 3D glasses use LCD shutters for each eye and a special sync transmitter built in to the TV to send a signal to keep the right and left eye shutters moving at the same time the picture viewpoint changes. They require replaceable or rechargeable batteries to power the shutters and are more expensive than passive models. Active 3D televisions are sold by the majority of manufacturers.
