Description

Progressive anti-blue light glasses

technical field

The utility model relates to glasses, in particular to progressive anti-blue light glasses.

Background technique

As human eyes degenerate with age, the focal length becomes longer, blurring the image of objects within a distance of 50-100 centimeters, while objects over 3-5 meters generally have little effect. This is the so-called presbyopia, which is a common phenomenon among middle-aged and elderly people over 40 years old. In order to correct the degeneration phenomenon of eyeball focal length change, human beings invented glasses, that is, by measuring the different degrees of eyeball degeneration of specific individuals, designing optical lenses adapted to specific individuals and fixing them on the frame to re-correct the deviated focal length of sight , This is reading glasses. Generally, reading glasses have only one focal length, which makes it easy for the elderly to read objects or characters at close range. If they are looking at distant objects, they must move their eyes away from the glasses, which causes a lot of trouble to use. In order to solve this problem, double-focal reading glasses appeared again. The designer designed the focal length of the upper half of the glasses to observe objects above 3 meters, while the lower half was designed to observe close-up scenery and characters. Such a design The wearer of the hyperopia glasses does not need to remove the glasses when observing distant/near objects, which provides great convenience for hyperopic people. Due to the different radians of the lens, the upper and lower parts of the lens form two completely different parts in the grinding of the two focal lengths of the far/near focal length. There is an obvious boundary line between the upper and lower parts of the lens. During use, when the wearer's line of sight moves from top to bottom or bottom to top, the eyeballs will constantly adjust, causing easy fatigue or dizziness. If the luminosity difference between far and near is high, there will be obvious "like jumping", which will cause dizziness and inability to judge high and low positions in some scenes in life (such as stairs, walking) to varying degrees.

As a result, a kind of gradient glasses appeared on the market. Traditional gradient glasses have large lenses, which are easy to slip off when worn by the elderly, and many people only know that ultraviolet rays can damage the eyes. They don’t know that blue light is more harmful to the eyes than ultraviolet rays in visible light. Because ultraviolet rays are usually partly absorbed by the cornea and lens, and generally do not directly irradiate the retina, blue light passes through the lens and is directly projected onto the retina. Long-term exposure to blue light in large quantities will cause immeasurable damage to the eyes. Among visible light, blue light with a wavelength of 435nm carries the most energy, has the strongest penetrating power, and is the most harmful to the eyes. Blue light will accelerate the oxidation of cells in the macular area of the retina, and excessive exposure may even damage visual cells. If the macular area receives blue light for a long time, it will increase the risk of macular degeneration in the eyes in old age, and even cause permanent vision loss.

Contents of the invention

The technical problem to be solved by the utility model is to propose a progressive anti-blue light glasses aiming at the deficiencies of the prior art.

The technical problem to be solved by the utility model is realized through the following technical solutions. The utility model relates to progressive anti-blue ray glasses, comprising spectacle frames, spectacle legs, and spectacle lenses. The spectacle frames are hinged to spectacle legs through hinges; Spectacle lenses are provided, and the feature is that the spectacle lenses are integrally injection-molded, and the spectacle lenses are vertically divided into two sides and a middle area, the upper part of the middle area is the far-sighted area, the middle part is the middle-sighted area, and the lower part is the near-sighted area. Both sides of the lens are blind areas, the inner surface of the spectacle lens is provided with a metal oxide film coating, and an ear hanging piece is connected to the bottom end of the spectacle leg, and the angle between the ear hanging piece and the spectacle leg is greater than 90° and Less than 180°.

In the technical solution of progressive anti-blue light glasses of the utility model, the further preferred technical solution features are:

1. The width of the middle area is 25-30mm, and the width of the blind area is 10-15mm;

2. The far vision zone, intermediate vision zone and near vision zone are respectively provided with 2, 4 and 2 focal points in sequence;

3. The outer surface of the spectacle lens is provided with an Ar anti-reflection coating, and the Ar anti-reflection coating is coated with a wear-resistant and scratch-resistant coating;

4. The spectacle legs are made of stainless steel or β-titanium and formed integrally by punching or corrosion or laser or cutting.

Compared with the prior art, the lens of the utility model is divided into the far-sighted area for watching scenery, playing, walking, etc., the middle-sighted area for watching computers, mahjong entertainment, etc., and the near-sighted area for reading books, reading newspapers, writing, needlework, etc. The blind area is specially designed to correct the habit of using the eyes and prevent the prescription from deepening. The spectacle lens has an anti-blue light coating to protect the eyes. The technology is simple, the cost is low, the appearance is relatively good, the function is unique, the principle is scientific, the use is simple, the curative effect is remarkable, and the quality is excellent.
