Description

Peripheral hyperopic defocus-resistant sheet and spectacles

Technical Field

The utility model discloses a sheet and glasses, in particular to sheet and glasses of anti peripheral hyperopia out of focus.

Background

Myopia refers to the focusing of an image of a distant object in front of the retina of the human eye, resulting in blurred vision. The existing simple and effective method is to wear concave lens optical glasses, i.e. myopia glasses, to make the light rays entering the eyeball diverge, so that the light rays are focused on the retina, and then the user can obtain clear images.

The human eyeball is ellipsoidal. According to the study, a common single lens has only one degree of vision, and objects seen through the central area of the lens can be clearly imaged on the retina, but the light rays entering through the peripheral area of the lens are imaged behind the retina, which is called peripheral hyperopic defocus. Because the human eye has the natural mechanism of "seeing objects" it is good for light rays entering through the peripheral zone to be imaged on the retina in order to eliminate the posterior elongation of the eyeball caused by peripheral hyperopic defocus. However, elongation of the axis of the eye also increases myopia. Therefore, it is an important issue to resist peripheral hyperopic defocus to avoid myopia progression.

Detailed Description

Fig. 1 is a schematic diagram of a sheet 100 resisting peripheral hyperopic defocus according to an embodiment of the present invention, and fig. 2 is a partial cross-sectional view of the sheet 100 resisting peripheral hyperopic defocus according to an embodiment of the present invention. Referring to fig. 1 and 2, a sheet 100 for resisting peripheral hyperopia defocus according to an embodiment of the present invention includes a micro-bump component 110, a release paper 120, and an adhesive 130.

The micro-bump feature 110 is made of, but not limited to, PET (Polyethylene Terephthalate). In one embodiment, the microprotrusion member 110 may be a flexible film. The microprotrusion member 110 has a central area 111 and a peripheral area 112. The central region 111 is located in the middle region of the microprotrusion member 110. In the present embodiment, the central region 111 is circular. In other embodiments, the central region 111 may have other shapes, such as an oval shape, or a shape that fits the eyeball. The central area 111 has a hollow portion or a plane, and the central area 111 has a hollow portion h as an example.

The peripheral region 112 surrounds the central region 111. The peripheral region 112 has a plurality of spaced apart microprotrusions p. The micro-protrusions p may be regularly or randomly arranged on the peripheral region 112. Additionally, in some embodiments, the portions of the peripheral zone 112 that are further from the central zone 111 may have a greater density of microprotrusions p (i.e., the number of microprotrusions per unit area) to increase the effectiveness against peripheral hyperopic defocus. The micro-bumps p are disposed on a side of the micro-bump component 100 opposite to the release paper 120, that is, the micro-bumps p are opposite to the release paper 120. In this embodiment, the microprotrusion member 100 is integrally formed. In one embodiment, the peripheral region 112 and the micro-protrusions p may be yellow, so as to resist blue light, thereby protecting the eyes of the user. In one embodiment, the peripheral region 112 and the micro-protrusions p may be orange or red, thereby inhibiting myopia. In one embodiment, the microprotrusions p are colorless and the portions of the peripheral region 112 that do not have microprotrusions are gray or brown, thereby resisting ultraviolet light and improving photophobia for users of spot mydriatics.

The adhesive 130 is disposed between the micro-bump component 110 and the release paper 120 to adhere the micro-bump component 110 and the release paper 120. In the present embodiment, the adhesive 130 can be exposed through the hollow portion h. In other embodiments, the adhesive 130 may not be exposed through the hollow portion h, i.e., no adhesive is disposed within the range of the hollow portion h.

The sheet 100 of defocus resistant to peripheral hyperopia can be fitted on a lens, for example, for near vision or presbyopia. In use, the release paper 20 is peeled off, and the micro-bump component 110 is adhered to the outer side of the lens by the adhesive 130, so that the micro-bumps p face to the outside and do not face to the user wearing the lens.

The sheet 100 that resists peripheral hyperopic defocus can also be attached to the eyeglasses and engaged with the lenses by, for example, magnetic attraction, fitting engagement, clamping, or mounting.

Fig. 3 is a partial cross-sectional view of another sheet 200 of material that is resistant to peripheral hyperopic defocus in accordance with an embodiment of the present invention. Referring to fig. 3, the sheet 200 resisting peripheral hyperopic defocus comprises a microprotrusion member 210, a release paper 220, and an adhesive 230, wherein the microprotrusion member 210 has a central area 211 and a peripheral area 212, and the peripheral area 112 has a plurality of spaced microprotrusions p. The technical features and relative relationship of the micro-bump component 210, the release paper 220, and the adhesive 230 can be referred to the above embodiments, and will not be described again. However, the main difference between the peripheral hyperopic defocus

resistant sheets

200 and 100 is that the micro-bump members 210 have the recesses 213, the bottom of the recesses 213 has the flat surface 214, and the flat surface 214 is parallel to the release paper 220. In other embodiments, the microprotrusion member 210 may not have a recess. Also, in embodiments without a recessed portion, the plane 214 of the central region 211 may be flush with the plane of the peripheral region 212. The plane 214 of the central area 211 has no optical design and therefore does not affect the optical effect of the lens 410. In one possible embodiment, the plane 214 of the central region 211 is a photochromic or opaque material, and is therefore suitable for being bonded to Glasses of Virtual Reality Glasses (VR Glasses) or Augmented Reality Glasses (AR Glasses), so as to facilitate users to view images more clearly under different indoor or outdoor illumination or/and reduce the damage of light to eyes under high illumination.

Fig. 4 is a schematic front view of another sheet 300 of material that is resistant to peripheral hyperopic defocus in accordance with an embodiment of the present invention. Referring to FIG. 4, the sheeting 300 resisting peripheral hyperopic defocus includes a plurality of sheeting zones, here exemplified by the sheeting zones 301-306. The sheet zones 301-306 are arranged in an array and separated by a plurality of cut lines s1-s 3. Each of the sheet areas 301-306 has the above-mentioned

micro-bump component

110 or 210, the

release paper

120 or 220, and the adhesive 130 or 230. By the above design, the peripheral hyperopic defocus sheet 300 can be mass produced. The user can cut the

respective sheet sections

301 and 306 along the cutting lines s1-s3 and use them.

Fig. 5 is a schematic diagram of a sheet material for resisting peripheral hyperopic defocus applied to glasses according to an embodiment of the present invention. Here, the sheet 100 for preventing peripheral hyperopic defocus is applied to the eyeglasses 400 as an example. Please refer to fig. 1 and fig. 2 to illustrate the present embodiment. In use, the release paper 120 of the sheet 100 is peeled off, and the micro-bump members 110 are adhered to the outer sides of the

lenses

410 and 420 of the glasses 400 by the adhesive 130. At this time, the central region 111 of the microprotrusion member 110 is centered on the

lenses

410 and 420. Additionally, the area of the central region 111 of the microprotrusion member 110 may be greater than or equal to the size of the user's eyes.

The sheet 100 that resists peripheral hyperopic defocus can also be attached to the eyeglasses 400 by, for example, magnetic attraction, fitting engagement, clipping, or mounting, and engaged with the lenses 410.

Fig. 6 is a schematic view of a ray path of a lens 400 applied with a sheet 100 for resisting peripheral hyperopic defocus according to an embodiment of the present invention. Referring to fig. 6, the microprotrusion member 110 is bonded to the lens 410 and has a central area 111 and a peripheral area 112. The central area 111 is located at the center of the lens 410 and has a hollowed-out portion h. The peripheral area 112 is disposed around the central area 111 and has a plurality of micro-protrusions p. The light rays entering the eyeball 500 through the central region 111 (including the hollow portion h) through the optical design of the lens 410 can be imaged on the retina 510. Light entering the eye through the peripheral region 112 is finally focused on the retina 510 or in front of the retina 510 by the micro-convex particles p. By avoiding focusing light on the retina 510, the user's eyes 500 are prevented from being elongated, thereby avoiding the myopia from being deepened. The entirety of the glasses 400 and the microprotrusion member 110 shown in fig. 5 and 6 is the glasses for resisting peripheral hyperopic defocus according to the embodiment of the present invention.

In summary, in the sheet and the glasses of the present invention, which are resistant to peripheral hyperopia defocus, the peripheral region of the microprotrusion member has microprotrusions. Light entering the eye through the peripheral region 112 is subject to the microprotrusions p and can be imaged on or in front of the retina. Therefore, the utility model discloses the effect that peripheral hyperopia defocused can be resisted to the sheet and the glasses of anti peripheral hyperopia defocused, and then has eliminated the factor that the axis of the eye elongates to reach the effect that suppresses the myopia and deepens.

The foregoing is by way of example only, and not limiting. It is intended that all equivalent modifications and variations not departing from the spirit and scope of the present invention be included in the appended claims.
