LENS MODULE AND EYEGLASS MODULE COMPRISING SAME

Description

TECHNICAL FIELD

The present disclosure relates to a lens module including a filter for people with a color deficiency and a glasses module including the lens module.

BACKGROUND

Specially coated lenses and eyeglasses for correcting color amblyopia have been developed for people with red-green color amblyopia.

By reflecting incident light between red light pulses and green light pulses and allowing the light having other pulses to be incident, red-green amblyopic people may readily distinguish the colors of red and green.

Nonetheless, while forming a filter for readily distinguishing red and green, the filter has been incapable of clearly distinguishing red and green, depending on the transmissivity and reflectivity of the filter.

Moreover, the light incident from the back of the person wearing the eyeglasses is often visible due to the reflectivity of the filter.

DETAILED DESCRIPTION

Hereinafter, certain embodiments of the present disclosure will be described with reference to the appended drawings.

In the drawings appended hereto, the scales and dimensions of certain elements have been exaggerated for the purpose of description and understanding. Any description including “and/or” should be understood to encompass one or more combinations that are definable by the elements associated with “and/or.”

Terms such as “include” are intended to designate the presence of certain features, numbers, steps, operations, elements, components or any combinations thereof and shall not be understood to preclude the presence or addition of one or more other features, numbers, steps, operations, elements, components or any combinations thereof.

FIG. 1 illustrates an example of a glasses module 10 in accordance with an embodiment of the present invention.

The glasses module 10 may include a frame 100 and a lens module 200.

The frame 100 is configured to fix the lens module 200 thereto and to be in direct contact with the face of a user. In an embodiment of the present invention, the frame 100 may be understood to be a glasses frame.

The frame 100 may include a first sub-frame 110 and a second sub-frame 120.

The first sub-frame 110 may be coupled with the lens module 200. The first sub-frame 110 may surround at least a portion of the lens module 200.

The second sub-frame 120 may include a first support 121 and a second support 122.

The first support 121 may be coupled with the first sub-frame 110. Although not shown explicitly, the first support 121 may be hinge-coupled with the first sub-frame 110.

The second support 122 may be extended from the first support 121. The second support 122 may make contact with an ear of the user to allow the glasses module 10 to be fixed to the face of the user.

The lens module 200 is configured to allow some of the light incident from an outside to transmit to provide the light to the user.

FIG. 2 illustrates an example of a section of the embodiment shown in FIG. 1 along the line indicated by I-I′.

Referring to FIG. 2, the lens module 200 may include a base member BS, a first hard coating layer HC1, a filter FT, a first water-repellent layer WR1, a second hard coating layer HC2, a light absorption layer AR and a second water-repellent layer WR2.

The base member BS may include a transparent material. In an embodiment of the present disclosure, the transparent material may be, but not limited to, a synthetic resin (or plastic). In another embodiment of the present disclosure, the transparent material may be glass. In an embodiment of the present disclosure, the base member BS may be dyed by a dye material to have a predetermined color.

The first hard coating layer HC1 may be disposed on the base member BS. A space between the first hard coating layer HC1 and the second support 122 may be greater than a space between the base member BS and the second support 122. That is, the first hard coating layer HC1 may be spaced further apart from the second support 122 than the base member BS is.

The first hard coating layer HC1 may prevent the base member BS from being damaged. In an embodiment of the present disclosure, the first hard coating layer HC1 may include silicon dioxide (SiO₂).

The filter FT may be disposed on the first hard coating layer HC1. A space between the filter FT and the second support 122 may be greater than a space between the first hard coating layer HC1 and the second support 122. That is, the filter FT may be spaced further apart from the second support 122 than the first hard coating layer HC1 is.

The filter FT may block light having specific wavelengths in the incident light from being transmitted. In an embodiment of the present disclosure, the filter FT may have a light transmissivity of 10% or lower for wavelengths between 555 nm and 565 nm of the incident light. Preferably, the filter FT may have the light transmissivity of 0.1% or lower for wavelengths between 555 nm and 565 nm of the incident light. That is, the filter FT may have a reflectivity of 99.9% or higher for wavelengths between 555 nm and 565 nm of the incident light.

As the filter FT does not allow the wavelengths between 555 nm and 565 nm of the incident light to be transmitted, the user wearing the glasses module 10 may distinguish and visually recognize the colors of red and green more clearly.

The stacking structure of the filter FT having the above-described functionality will be described in more detail with reference to FIG. 3.

The first water-repellent layer WR1 may be disposed on the filter FT. A space between the first water-repellent layer WR1 and the second support 122 may be greater than a space between the filter FT and the second support 122. That is, the first water-repellent layer WR1 may be spaced further apart from the second support 122 than the filter FT is.

The first water-repellent layer WR1 may prevent, for example, water droplets from forming on a surface of the lens module 200. Moreover, the first water-repellent layer WR1 may prevent, for example, stains caused by the user's fingerprints from forming on the surface of the lens module 200. In an embodiment of the present disclosure, the first water-repellent layer WR1 may include a hydrophobic material. The hydrophobic material may include fluorine.

The second hard coating layer HC2 may be disposed underneath the base member BS. A space between the second hard coating layer HC2 and the second support 122 may be smaller than a space between the base member BS and the second support 122. That is, the second hard coating layer HC2 may be disposed closer to the second support 122 than the base member BS is.

The second hard coating layer HC2 may prevent the base member BS from being damaged. In an embodiment of the present disclosure, the second hard coating layer HC2 may include silicon dioxide (SiO₂).

The light absorption layer AR may be disposed underneath the second hard coating layer HC2. A space between the light absorption layer AR and the second support 122 may be smaller than a space between the second hard coating layer HC2 and the second support 122. That is, the light absorption layer AR may be disposed closer to the second support 122 than the second hard coating layer HC2 is.

The light absorption layer AR may absorb at least a portion of the incident light. In an embodiment of the present disclosure, the light absorption layer AR may include silicon dioxide (SiO₂) and zirconium oxide.

Specifically, the light incident from underneath the lens module 200 (i.e., the light incident from the back of the user wearing the glasses module 10) passes through the second water-repellent layer WR2 before being absorbed by the light absorption layer AR. The light having passed through the light absorption layer AR successively passes through the second hard coating layer HC2, the base member BS and the first hard coating layer HC1 before reaching the filter FT. Since the filter FT has the reflectivity of 99.9% or higher for the light having wavelengths between 555 nm and 565 nm, the light reflected by the filter FT passes through the first hard coating layer HC1, the base member BS and the second hard coating layer HC2 successively before reaching the light absorption layer AR. As some of the reflected light is absorbed by the light absorption layer AR, the user wearing the glasses module 10 does hardly recognize the light being incident from the back of the user. That is, the light absorption layer AR may function to prevent the light being incident from the back of the user from being visible in the user's field of view.

The second water-repellent layer WR2 may be disposed underneath the light absorption layer AR. A space between the second water-repellent layer WR2 and the second support 122 may be smaller than a space between the light absorption layer AR and the second support 122. That is, the second water-repellent layer WR2 may be disposed closer to the second support 122 than the light absorption layer AR is.

The second water-repellent layer WR2 may prevent, for example, water droplets from forming on the surface of the lens module 200. Moreover, the second water-repellent layer WR2 may prevent, for example, stains caused by the user's fingerprints from forming on the surface of the lens module 200. In an embodiment of the present disclosure, the second water-repellent layer WR2 may include a hydrophobic material. The hydrophobic material may include fluorine.

Referring to Table 1 above and FIG. 4, the lens module 200 including the filter FT illustrated in FIG. 3 has the light transmissivity of about 0.0193 for light having the wavelength of 555 nm, the light transmissivity of about 0.01 for light having the wavelength of 560 nm, and the light transmissivity of about 0.0356 for light having the wavelength of 565 nm. That is, the lens module 200 in accordance with an embodiment of the present disclosure may have a very low light transmissivity of 0.1% or less for wavelengths of 555 nm or greater and 565 nm or less. This very low light transmissivity for the wavelengths of 555 nm or greater and 565 nm or less may be owing to silicon aluminum oxide and titanium niobium oxide included in the filter FT. In the light, the wavelength between about 380 nm and 425 contributes to violet in color, the wavelength between 425 nm and 450 nm to indigo, the wavelength between 450 nm and 495 nm to blue, the wavelength between 495 nm and 570 nm to green, the wavelength between 570 nm and 590 nm to yellow, the wavelength between 590 nm and 620 nm to orange, the wavelength between 620 nm and 780 nm to red. In other words, the light of about 580 nm to 780 nm of wavelength is reddish color, and the light of about 495 nm to 580 nm is greenish color, and the light of about 380 nm to 495 nm of wavelength is bluish color.

As red-green color amblyopia is a deficiency in distinguishing greenish color and reddish color, a red-green color amblyopic person wearing the glasses module 10 may readily distinguish color green and color red when the lens module 200 of the glasses module 10 preponderantly reflects the light having wavelengths between 555 nm and 565 nm that are between green and red.

FIG. 5 illustrates an example of a section of the embodiment shown in FIG. 1 along the line indicated by I-I′.

Referring to FIG. 5, a lens module 200-1 may include a base member BS-1, a first hard coating layer HC1-1, the filter FT, the first water-repellent layer WR1, a second hard coating layer HC2-1, the light absorption layer AR and the second water-repellent layer WR2.

The base member BS-1 is not dyed by a dye material, unlike the base member BS shown in FIG. 2.

Each of the first hard coating layer HC1-1 and the second hard coating layer HC2-1 includes tungsten oxide or chrome oxide, and thereby the first hard coating layer HC1-1 and the second hard coating layer HC2-1 may each have a predetermined color. That is, even though the base member BS-1 is not dyed by a dye material, the lens module 200-1 may still have a predetermined color, owing to the color exhibited by each of the first hard coating layer HC1-1 and the second hard coating layer HC2-1.

Other elements of the lens module 200-1 are identical with the elements of the lens module 200 described above and thus will not be described redundantly.

While certain embodiments of the present disclosure have been described, anyone of ordinary skill in the art to which the present disclosure pertains would appreciate that various modifications or permutations to the present disclosure may be available without departing from the technical ideas and scope of the present disclosure described in the appended claims. Moreover, it should be appreciated that the embodiments described in the present disclosure are not intended to limit the technical ideas of the present disclosure thereto and that the claims appended below and every other technical idea within the equivalent claim scope are included in the scope of protection of the present disclosure.
