Abstract

An ophthalmic lens, comprising: the central region of the lens has a fully transparent area surrounded by an opaque or translucent area outside the fully transparent area. The radius of the fully transparent region (or the length and width of the region) is greater than 3 mm. The radius of the fully transparent area (or the length and width of the area) is less than 30 mm. The invention provides a device for relieving fatigue of brain and eyes to at least a certain extent when people watch things, particularly characters and the like, for a long time. The method can be used for providing help for people with reading disorder at least to a certain extent, can increase the reading effect or degree of the people with reading disorder on the text content at least to a certain extent, and can advance the time or period for the people with reading disorder to start reading at least to a certain extent.

Description

Lens

Technical Field

The invention relates to the field of optics, in particular to a lens.

Background

The invention provides a device for relieving fatigue of brain and eyes to at least a certain extent when people watch things, particularly characters and the like, for a long time. The method can be used for providing help for people with reading disorder at least to a certain extent, can increase the reading effect or degree of the people with reading disorder on the text content at least to a certain extent, and can advance the time or period for the people with reading disorder to start reading at least to a certain extent. The invention can be used to provide at least some increased efficience when worn at leisure. The present invention can at least to some extent make the wearer look different or individual.

Disclosure of Invention

According to one aspect of the present disclosure, a lens, comprising: the central region of the lens has a fully transparent area surrounded by an opaque or translucent area outside the fully transparent area.

Preferably, the full transparency is with respect to the human eye.

Preferably, the central region of the lens is the region near the point where the pupil is aligned.

Further, the center of the fully transparent area may be close to or overlap the point in the lens where the pupil is aligned.

Preferably, the full transparency may be near full transparency or considered full transparency by the human eye, or considered near full transparency by the human eye.

Alternatively, the lens outline shape of the invention may be a lens shape that is not infringement in that the key to the invention is a fully transparent aperture in the middle of the lens, the aperture being characterized as in the claims, and the aperture being surrounded by a translucent or opaque area, as also described in the claims.

Preferably, the radius of the fully transparent region (or the length and width of the region, or the length and width of the region containing box) is greater than 3 mm.

Preferably, the radius of the fully transparent region (or the length and width of the region, or the length and width of the region containing box) is less than 30 mm.

Preferably, the shape (or the shape of the planar projection) of the fully transparent region may be circular, oval, arc, rectangular, diamond.

Preferably, the fully transparent area may be an intermediate fully transparent area obtained by cutting or perforating a semi-transparent or opaque lens.

Further, as an alternative embodiment, the perforation may be performed using a laser.

Preferably, the opaque or translucent region outside the fully transparent region can be achieved by applying one or more opaque or translucent films.

Preferably, as an alternative embodiment, the opaque or translucent area outside the fully transparent area may be realized by painting or spraying an opaque or translucent paint.

Preferably, the opaque or translucent region outside the fully transparent region may be implemented by an opaque or translucent material.

Preferably, as an alternative embodiment, the material color of the opaque or translucent area may be black.

Preferably, as an alternative embodiment, the material color of the opaque or translucent area may be green.

Preferably, the lenses can be deployed on eyeglasses as well as on spectacle frames.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.

Fig. 1 schematically shows a layout of a fully transparent area and an opaque or semi-transparent area of a lens, top view.

Detailed Description

The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Example 1

Step 1: a piece of sunglass lens is put on a laser device at a calibration position, and then an area around a point of the sunglass lens, which is aligned with the pupil, is cut out by the laser device so that the projection shape of the plane of the cut-out area set in the lens direction is circular. The same operation is performed for the other lens, so that a hole appears in the middle of the sunglass lens.

Step 2: two symmetrical sunglass lenses are mounted on a (or ancient spindle knife) lens holder. The lens clip is clipped to the eyeglasses and the user looks through both fully transparent areas (the fully transparent apertures).

And step 3: when a user sees things through two fully transparent areas (fully transparent holes), the fully transparent holes are large (larger than 3 mm), so that the user can have a better visual field, and the semi-transparent areas around the fully transparent holes can shield light better. When the characters exceed the visual field corresponding to the current full transparent area during reading, the visual field can be adjusted by moving the head to continue reading, and the action of turning the head is not frequent due to the large full transparent hole.

Example 2

Step 2: two symmetrical sunglass lenses are mounted on (or in a ancient spindle knife) eyeglasses. The glasses are brought to the user's head (where the glasses are worn) and the user then looks through the two fully transparent areas (the fully transparent holes).

And step 3: when a user looks through two fully transparent areas (fully transparent holes), the fully transparent holes are large (larger than 3 mm), so that the user can have a better visual field, and meanwhile, the opaque areas around the fully transparent holes can also have a better shielding effect on light. When the characters exceed the visual field corresponding to the current full transparent area during reading, the visual field can be adjusted by moving the head to continue reading, and the action of turning the head is not frequent due to the large full transparent hole.

The above is a specific embodiment of the present invention, but the scope of the present invention should not be limited thereto. Any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention, and therefore, the protection scope of the present invention is subject to the protection scope defined by the appended claims.
