Difference between revisions of Differentials

Line 1:

Differentials are glasses for close-up.

'''Differentials''' are reduced glasses for [[close-up|close up activity]]. They have a lower correction than your [[normalized]] lenses that allows you to see clearly only up to the screen. The difference between [[normalized]] and differential lenses is usually between 1 and 2 [[diopters]].<ref>https://endmyopia.org/faq-items/what-is-the-differential-prescription/</ref><ref>https://endmyopia.org/choose-reduced-glasses-prescription-differential-close-friendly-glasses/</ref>

~~They should have a lower correction than your~~ [[~~normalized~~]] ~~lenses~~ that ~~allows you~~ to see ~~clearly only~~ up to the ~~screen~~.

==Why are differentials worn?==

The primary stimulus for [[axial elongation]] of the eyeball is [[hyperopic defocus]], which occurs when someone:

* Is engaged in close-up activity

* Wears more correction than they need to when seeing the object that is close up.

Differentials allow the wearer to wear ''just what they need to'', to see up close. This removes the stimulus of hyperopic defocus, and stops eyes from getting more myopic. In a sense, it's a [[quick fix]]. {{wink}}

It's fairly easy to <u>stop myopia from progressing</u>, just by wearing differentials. The axial length of the eye does not randomly change by itself, it only increases in response to [[stimulus]].

~~The difference between [[normalized]] and differential lenses is usually between 1 and 2 [[diopters]].~~
