Description

A device that can quickly and autonomously screen the required optical power

The present invention relates to a device capable of quickly and autonomously screening required optical powers.

People often have blurred vision due to improper use of vision or aging factors. For example, after the age of 40, due to the gradual degeneration of the ciliary muscle and lens of the eye, proper focusing action cannot be performed, resulting in the inability to accurately focus on the retina when looking at a close distance, resulting in Presbyopia that cannot be clearly visualized.

At present, optometry personnel can use optometry machines to detect their degrees in eyeglasses shops. Generally, one wears a pair of eyeglasses first, and then displays the symbols or numbers on the near-use label on the optometry machine, and wears more after viewing. Or the lens with reduced power is re-reviewed on the optometry machine for the near-use symbols or numbers. In this way, the lenses with different powers are repeatedly worn to obtain the lens with the clearest view and its appropriate power. However, the user takes off the lens and refits it after a few seconds. When wearing another power lens, the user may forget the viewing status of the previous lens, and it is difficult to select the most appropriate power lens.

In addition, although the above-mentioned method can detect the appropriate degree, the user must go to the glasses shop to be instructed by an optometrist and repeatedly wear glasses of different degrees before being detected by the optometry machine.

For example, when people need to watch, read or fill in information at close range in various public places such as exhibition venues and stores, because people may not carry or configure reading glasses, reading glasses of different degrees (such as +1.0, +1.5, + 2.0, +2.5, +3.0, +3.5 degrees) for people to wear and use temporarily and then return it, but the user is not easy to choose the appropriate degree of glasses because he does not know the degree, and he cannot choose the appropriate degree of glasses when there is a temporary need. .

In addition, for short-sighted users, it is also troublesome that glasses of appropriate degree cannot be selected for temporary use due to the inability to quickly detect and measure the degree.

The object of the present invention is to provide a device that can provide users with quick screening of required optical powers.
