Smart patch for contact lenses

The invention relates to a patch, in particular to a smart patch which is used with a contact lens and which increases the additional function of the contact lens without affecting the function of correcting the vision of the contact lens.

A contact lens is a lens that is worn on the cornea of the eye to correct vision or protect the eye. Since the contact lens has no heavy frame and lens, it has the characteristics of small size, convenient carrying, and does not affect the appearance of the user, and does not feel the burden on the use and does not affect the external beauty. Therefore, since the invisible Since the advent of glasses, they have been loved by all walks of life, especially nowadays, young people and beauty-loving people have resorted to wearing contact lenses to make up for their lack of vision.

With the change of the times and the maturity of technology, in addition to the function of correcting vision, contact lenses can also be embedded in the inside of contact lenses, and the basic metabolic values in tears can be detected through microelectronic devices. People can know the changes in blood sugar levels in the body.

However, currently contact lenses with microelectronic devices are directly embedded in the inside of the contact lens during processing, and it is quite difficult to install a microelectronic device on the spherical surface. Therefore, the use of contact lenses with microelectronic devices is limited. More and less degree of selectivity, when the wearer's myopia or far-sight degree changes, it is necessary to purchase another contact lens with a micro-electronic device to wear, which causes inconvenience in use.

In addition, conventional contact lenses with microelectronic devices, if they have the effect of detecting blood sugar and correcting vision, tend to sell at a much higher price than general contact lenses. Once the price is higher, the relative purchaser’s willingness to purchase It will decrease.

In view of this, there is still a deficiency in the use of contact lenses having microelectronic devices, and there is a need to improve and innovate custom contact lenses by creating a smart patch that can be attached to the surface of the contact lens. Without affecting the general contact lens to correct the eyesight function of the eye, the general contact lens can have the function of detecting the blood sugar by the micro electronic device through the smart patch.

The main purpose of the invention is to adsorb the smart patch on the surface of the contact lens, and to increase the additional function of the contact lens without affecting the function of correcting the vision of the contact lens, and then to wear the contact lens, so that the wearer is invisible A smart patch on the surface of the glasses that monitors blood sugar or other metabolic values.
