Description

Light filtering paster for glasses

Technical Field

The present invention relates to a light filtering patch, and more particularly to a patch having one or more filter layers, which can be cut in real time according to the size and shape of a lens and attached to the lens for use, so that the lens has the function of filtering light.

Background

With the rapid development of acousto-optic audio-visual media and the popularization of portable mobile communication mobile phones, people can obtain information conveniently, the eyesight of the eyes is easy to fatigue and deteriorate, and the proportion of myopia of children is increased year by year under the stimulation of acousto-optic equipment. Besides the acousto-optic devices, sunlight and even various light rays with different wavelengths emitted by Light Emitting Diodes (LEDs) can affect the eyesight of people, so that the number of people wearing the glasses is increased or decreased.

Although the rapid development of optical technology has led to the spectacle lenses having various functions, such as corrective spectacle lenses for myopia, hyperopia and presbyopia, or bifocal spectacle lenses suitable for both myopia and hyperopia. However, ophthalmic lenses with multiple functions or special effects are often expensive and can be accepted by non-ordinary income. In order to meet the requirements of people who cannot bear high-price spectacle lenses and need to achieve the light filtering effect, dark-color plastic spectacle lenses equivalent to the spectacle lenses in size have been developed in the workshop.

As shown in fig. 1, the conventional dark color plastic glasses auxiliary piece 10 is clamped on the frame 40 of the glasses 30 by a clamp 20, and since the clamp 20 has a function of lifting the plastic glasses auxiliary piece thereon, the dark color plastic glasses auxiliary piece 10 can be vertically hung in front of the glasses lens 50 according to the needs of the user when the user needs to block the light, so that part of the light can be blocked, and the light passing through the glasses lens and entering the eyes can be reduced; when the light blocking is not required, the bottom edge of the dark-colored plastic spectacle sub-piece 10 is lifted up, so that the plastic spectacle sub-piece 10 is laid flat on the spectacle lens 50.

However, although the dark color plastic glasses auxiliary piece 10 capable of being flipped can achieve the effect of blocking light, the user only has two options of blocking light and not blocking light, and the dark color plastic glasses auxiliary piece 10 is clamped on the glasses frame 40 for use, and is easy to fall off, which also increases the obstacle of the visual angle of the eyes. The existing glasses auxiliary piece can not meet different requirements of people at different times.

In view of the above, the inventor develops the novel spectacle filter patch after continuous research and experimental improvement aiming at the defects of the conventional dark-color plastic spectacle auxiliary lens by accumulating the manufacturing experience and technology of various optical spectacle articles.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model aims at providing a glasses filter paster, this filter paster is via the soft gluey material shaping of elasticity such as latex, can select the back by people according to the demand of oneself, according to the big or small shape of lens, cuts immediately to in time attached use on the lens.

According to the utility model discloses a glasses filter paster, it has the filter layer more than one deck or one deck, should filter the paster and combine with a release paper after the shaping, make its portable or transport to must protect the paster not hurt, this does the utility model discloses a next purpose.

According to this novel glasses filter paster, its filter layer is formed on this paster substrate colloid's surface with the coating film mode, or sneak into the dyestuff of different colours in the colloid substrate when the paster shaping, and fuse as an organic whole with the paster, this does the utility model discloses a further purpose.

According to the utility model discloses a glasses filter paster, it can be according to the wavelength of light, and the preparation can block the light of specific wavelength intensity even, reaches people's most appropriate demand, and this is this novel another purpose.

According to the utility model discloses a glasses light filtering paster, because the thickness of this paster can be very thin, its surface is level and smooth, when attached on the glasses piece, does not have the clearance completely between the two, can become almost as an organic whole with the lens is attached completely, so can not have the situation that drops or influence the visual angle, do the utility model discloses a still another purpose.

To facilitate further understanding and appreciation of the objects, shapes, structural features and functions of the present invention, the present invention will be described in detail with reference to the accompanying drawings, in which:

Detailed Description

In the present novel eyewear filter patch, as shown in fig. 2, the filter patch 100 is formed by molding a plastic material, and has one or more filter layers 200. The base material of the filter patch 100 is preferably an elastic soft material with a smooth surface, such as latex. The filter layer 200 may be a coating film formed on the surface of the filter patch 100, or formed integrally by mixing a glue material and a dye.

Referring to fig. 3, the filter patch 100 is combined with a release paper 300 after being formed, so that the filter patch is protected from being scratched and is convenient to carry or transport.

Referring to fig. 4, after the filter patch 100 is combined with the release paper 300, the lens can be cut in real time according to the size and shape of the lens, and can be attached to the lens for use, so that the lens has the function of immediately filtering light.

This neotype glasses filtering paster has high mobility, can be according to the filtering classification, forms the filtering paster of following difference of power:

A. filter patch for completely blocking harmful light

A-1. invisible light

Below UV400 (commonly known as UV resistance).

UV700 or above (commonly known as anti-infrared).

A-2. visible light

Below a.UV420 (commonly known as high energy violet light resistance).

B. Filter patch for incompletely blocking light harmless to human body

And B-1. a polarized light filtering patch for blocking polarized light.

B-2. dark or light color filter patch for partially blocking sunlight.

And B-3. light-color polarized light filtering patch for improving indoor light and shade contrast.

And B-4. a polarized light filtering patch for polarizing the 3D image.

And B-5, filter patches (such as red and blue) for complementary color 3D images.

B-6. Filter patch for partial UV 450-550 blocking (commonly referred to as medical grade filter).

And B-7, a photochromic light-filtering patch.

B-8, a filter patch partially blocking visible light.

C. Optical patch for changing optical path

C-1, adjusting the optical spherical power and astigmatic power of the glasses.

C-2. multifocal optical auxiliary patches.

Therefore, the user can attach the glasses piece for use according to the needs and interests of the user at any time, so that the glasses piece has an immediate light filtering effect and the overall feeling of the glasses piece is not influenced. Even, the release paper may be dispensed with.
