Folding Reading Glasses

Purpose

Presbyopia

The 'near point' of our vision is the minimum distance from the eye that an object can be clearly focused. For a young adult, this is around 10cm. With advancing age, our lens loses elasticity and hence its ability to focus (accommodate). Because of this, older people cannot read print at the same close range as they once did when younger. This condition is termed presbyopia.

Age Related Presbyopia

By the time we reach 40, the 'near point' may have increased to around 20cm. By the age of 60, there may be a further increase to about 80cm. Presbyopia usually begins to manifest itself when we are in our mid forties. Around this time, people who already wear single vision glasses for distance start to need bifocals. Folks who have never previously worn glasses begin to require them for reading and close work.

Remedy

The FTZ folding reading glasses restore clarity when then lenses ability to accommodate becomes reduced. The powers available range from +1.0 to +3.5 dioptre in increments of 0.5 dioptre.
