Description

1234023 V. Description of the invention (1)---- " [Technical field to which the invention belongs], The present invention relates to a color contact lens. In particular, the present invention relates to a color contact lens having a holographic pattern. [Previous technology] In recent years, due to the development of color contact lenses, in addition to the original medical functions (vision correction), functions such as beauty and loose makeup have been added. There are not many occasions for use of colored contact lenses in the t period, and most of them are used for dance performances, but recently, colored contact lenses have gradually become a kind of 佶 Γ Even if young people do not have myopia, they will wear colored contact lenses ^ Bar 'The vision Γ that did not increase the wearing time and frequency of colored contact lenses. It was pointed out in a recent research report that evaluation results such as f-vision mitigation and wearing comfort among colored contact lenses showed that at night * \% TTj Often when the eye is insufficient, 'color contact lens lenses can not keep the wearer in a normal towel, not fit, also on, can do, 5 k into personal injury' even more when driving or exercising Reachable and innocent. , JN t ° The pupils of the human eye will expand or contract with the brightness of the light ° Y 列 士 ϋ 胳 \-nB ni The pupils of the eyes on the eyes of the umbrella are usually enlarged, sometimes larger than the six-hole visual The perimeter of the colored contact lenses are colored, which makes the size of the pupils' day and nine products redundant. Generally speaking, this color contact lens J can be inserted into the ancient world, χ§ Γττ σ °, the size of I is about four to six millimeters (mm). In Germany, a study on private eyes (11.% see 'wearing such colored contact lenses for a long time, the visual range and clarity at night may be affected.

1234023 V. Description of the invention (2) In addition, it is used to prepare colored lenses, which will harm the eyes of users. In order to make the colors more diversified, contact lenses are added without authorization. This color mirroring, but even if used only once, develops another type of colorist's injury, which has its need. For this reason, hologram is a direction of development. In recent years, it has been applied to a variety of product types. The so-called holographic technology refers to the method of forming a master of a holographic film on a sheet. The method of photoresist is a method of forming a surface by the development of a photoresist. There are two direct methods. After obtaining the master of the full-image film, a mold is obtained. This can then be used to mass produce full-images. Because the principle of optical interference is not required in the holographic technology, it will not hurt when the stereo comes into direct contact with the human body. Therefore, the present invention is directed to glasses. The dyes and pigments of the shape glasses are more or less already added on the market. Some manufacturers have added unapproved pigments and dyes. Although the price is cheap and the colors are more diverse, it will cause great damage to the eyes. In order to reduce the use of colored contact lenses, the technology should be able to provide colored contact lenses. In addition, holographic technology has gradually matured, and, for example, laser labels, CD discs, and decorations record the interference fringes of light on the photosensitive base. Traditionally, methods such as agents are used to record the required interference fringes, and then the master of the undulating pattern. After the interference fringe interference method and the computer simulation interference fringe method, the master is then cast, and the mold can be flattened or rolled, that is, using dyes or pigments, which uses the physical body color effect, so it has a full body effect. Like objects, the toxicity of chemical dyes causes the body to provide a color invisibility with a full image

1234023 V. Description of the invention (3) [Summary of the invention] The object of the present invention is to provide a color contact lens with a hologram to avoid damage to the eyes caused by chemical dyes or pigments contained in conventional color contact lenses. Another object of the present invention is to provide a color contact lens with a full image, so that the color contact lens can present stereo vision. Yet another object of the present invention is to provide a color contact lens with a full image, so that when a third party looks at the eyes of a user, different color presentations can be viewed with different viewing angles. Due to the vision that human eyes can receive, it is caused by external light entering the eyes through the pupil to form an image, and parts other than the pupil (for example, the iris) are not responsible for receiving external light sources. Therefore, according to the present invention, a color contact lens with a hologram is provided on the contact lens lens with a perforated optical region for enabling the pupil of the eye to receive an external light source. The lenses in the optical region of the pupil are generally invisible. The spectacle lens is the same, and may have a diopter or no diopter, which is not particularly limited herein. In addition, the diameter of the pupil of the eye can be adjusted by the intensity of external light to control the amount of light entering the eye. In general, the diameter of the pupil is mostly less than 4 micrometers (mm). Therefore, in order to make the external light that the eye can receive is sufficient and will not affect the visible range of the eye, the diameter of the pupil optical area is preferably 4 ~ 10 microns, more preferably 6 to 8 microns. In addition, a full-image area having a plurality of fine lines capable of presenting an optical interference phenomenon is provided around the pupil optical area, so that the color contact lens can present a full-color color appearance at the full-image area. This fine texture can be pre-imaged

1234023 In addition to the colorful D-shaped dagger, it is 'because the 4 daggers that use materials or colors can be borrowed without limitation'. It can be used for color and freely. This principle is full of holographic images, so the material injury is caused by reference. The book is made with some preparations. It can be prepared in the conventional way.) The color rendering with holographic mirrors presenting the colors at the viewing angle and presenting the somatosensory colors is the eye damage of the users who have achieved the color. The following implementations reveal the improvements and modifications previously disclosed. V. Description of the invention (4) Ink or holographic film layer is used to make molding) or spin molding (spi is attached to contact lenses. Borrowing glasses. Another type of contact lens presented by the user changes the color of the flat surface, which is a scientific dye or pigment. The artist category of these examples. Cast molding method (cast) When preparing contact lenses, it has a full image The effect of invisible colored contact lenses can be mentioned in a way, and by the difference of contact lenses, the different presenting effect will not be the color effect created by the light interference of small lines, so there is no need to use eyes to wear It will not be further explained by the dyeing example at the time. This shows the content. Familiar with the present invention, but still does not depart from the [Embodiment] of the present invention. See the first picture, the exhaustion diagram of the contact lens 100.
