Blue light blocking eyewear and method of use

An eyewear includes an eyewear frame; and two lenses held in place via the eyewear frame, each of the two lenses having a top portion composed of a clear polycarbonate; and a bottom portion integral with the top portion and composed of an orange polycarbonate; the bottom portion absorbs blue light and the top portion allows all light through.

BACKGROUND

1. Field of the Invention

The present invention relates generally to eyewear systems, and more specifically, to a blue light blocking eyewear for use with electronic devices.

2. Description of Related Art

Eyewear systems are well known in the art and are effective means to block sunlight, improve vision, and protect the wearer's eyes. For example,FIG.1depicts a conventional eyewear101having a frame103supporting clear lenses105,107. Eyewear101may be useful to improve the user's vision.

One of the problems commonly associated with eyewear101is limited use. For example, the eyewear101does not aid in protecting the wearer's eyes from blue light emitted from electronics. It is desirable to block blue light for a variety of reasons. Blue light is a high energy visible light that packs more energy than other light waves and penetrates all the way to the back of the eye (the retina). Excessive exposure to blue light can cause harmful effects to the eye.

Accordingly, although great strides have been made in the area of eyewear, many shortcomings remain.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The system and method of use in accordance with the present application overcomes one or more of the above-discussed problems commonly associated with conventional eyewear. Specifically, the present invention provides for eyewear having lenses that include an orange portion, thereby providing lenses that the user can wear, tilt their head, and either utilize a clear portion or the orange tinted portion to block blue light during electronic use. These and other unique features of the system and method of use are discussed below and illustrated in the accompanying drawings.

Referring now to the drawings wherein like reference characters identify corresponding or similar elements throughout the several views,FIG.2depicts an isometric view of a blue light blocking eyewear201in accordance with a preferred embodiment of the present application. It will be appreciated that eyewear201overcomes one or more of the above-listed problems commonly associated with conventional eyewear.

In the contemplated embodiment, eyewear201includes a frame203supporting two lenses205,207. Each lens has a top portion209,211composed of clear polycarbonate and a bottom portion213,215composed of an orange polycarbonate. It should be appreciated that the top and bottom of each lens are fused together in a seamless fashion, thereby providing for visibility through the entire lens seamlessly. However, alternative embodiments contemplate use of a film or other exterior layer to be added to a lens to provide for the blue light blocking functionality. It should further be appreciated that the eyewear can be a frameless style, still having a structural component to support the lenses.

It should be appreciated that one of the unique features believed characteristic of the present application is the bottom orange portion of the lens. This provides for eyewear that can be utilized with the orange portion to block blue light, and also provides for a clear portion that can be utilized when the user desires to have full visibility. This allows for the user to use a single pair of glasses for multiple uses. It should be appreciated that blue light can come from electronics, phones, the sun, and is essentially everywhere.

It should be appreciated that the lens can vary in shape and size, and further can include prescriptions or the like depending on the needs of the user.

InFIG.3, one embodiment of a lens205is shown, wherein the top portion209is clear and the bottom portion213is orange. In this embodiment, the length of the top and bottom portions (A, B) are approximately equal. However, it is contemplated that the length can vary. It should be appreciated that in all embodiments, the bottom portion is orange, as having the top orange would not be ergonomically appealing for the user. It should further be appreciated that the bottom portion can vary in intensity of orange.

InFIG.4, a side cross sectional view taken from line C ofFIG.2of lens205is shown in use with an electronic device401. As shown, during use, the user can wear the eyewear and use an electronic device. The electronic device401will emit blue light403which will pass through the clear top portion209but be blocked by the bottom orang portion211. It should be appreciated that the user can merely tilt their head backwards to make sure they are viewing the electronic device through the orange portion. It should further be appreciated that the lenses are composed of colored and clear polycarbonate, as opposed to a surface film or the like. This ensures that the orange color is disposed through a thickness of the lens and provides for optimal blue light blocking.

InFIG.5, a flowchart501depicts a method of use of eyewear201. During use, the user will wear the eyewear and view an electronic device, such as a TV, a smart phone, or a computer, wherein the bottom orange portion of the lenses block blue light from reaching the user's eyes, as shown with boxes503,505,507.
