Description

Technical Field

[0001] The present invention relates to the technical field of contact lenses, and in particular to a moisturizing contact lens and a manufacturing method thereof. Background Art

[0002] The existing contact lens manufacturing methods include turning, spin molding and casting. Among them, the turning method has a complicated manufacturing process and is not suitable for mass production, the spin molding method is difficult to use for producing lenses with high complexity, and the casting method can be used for both mass production and for producing lenses with high complexity, so currently, contact lenses are mostly made by the casting method. The casting method mainly involves injecting a liquid raw material into a designed mold, and then curing the liquid raw material in the mold by UV curing or heat curing, and then removing the mold after cooling to obtain the contact lens. The casting method takes about 1 minute to cool down, but in actual production, in order to pursue production efficiency, the liquid raw material is usually injected into the mold and immediately demolded after curing, so that the pores designed for ventilation on the contact lens are easily blocked due to high-temperature demolding, excessive cooling, and severe shrinkage, so that the existing contact lenses are prone to problems such as hypoxia of the eyeball and discomfort in wearing due to poor air permeability, poor oxygen permeability, and lack of hydrophilicity.

[0003] After wearing contact lenses, they cover the surface of the eyeball. In addition to affecting the secretion of tears, they also squeeze tears out. As a result, when wearing contact lenses for a long time, the eyes are prone to dryness and discomfort due to lack of water. Therefore, when wearing contact lenses, people will relieve the problem of dry eyes by using eye drops or artificial tears. However, regular eye drops or artificial tears not only cause the trouble of wearing contact lenses, but also increase the economic cost burden by purchasing eye drops and artificial tears separately. Moreover, if the eye drops and artificial tears used contain preservatives, they will also cause risks such as corneal ulcers. Therefore, how to increase the water content of contact lenses has always been the focus of contact lens research and development. The existing methods for increasing the water content of contact lenses mainly focus on material improvement, such as the paper "Study on the Optimization of Silicone Hydrogel Contact Lens Formula and Surface Modification" published by the Department of Materials Science and Engineering of Yangming Chiao Tung University. The paper consists of two parts. The first part is the formula development and optimization of silicone hydrogel contact lenses, and the second part is to use surface modification technology to modify a variety of contact lenses to achieve the purpose of optimizing performance. Among them, the first part selects a suitable combination from large-molecule silicon-containing monomers and small-molecule silicon-containing monomers to find the best formula for forming silicone hydrogel contact lenses to improve the tensile strength and Young's modulus of the contact lenses. The second part modifies the surface of the silicone hydrogel contact lenses prepared in the first part to optimize their hydrophilicity, lubricity and moisturizing properties, and explores the modification mechanism of the moisturizing factor. Through testing, it is found that interspersing the moisturizing factor in the grid of the contact lens polymer can achieve the modification effect of improving lubricity and moisturizing properties. However, although the material modification method can achieve the purpose of increasing the water content of contact lenses, its manufacturing process is complicated and time-consuming, prone to errors, and has a high manufacturing cost, which cannot meet the current industry demand for high efficiency and low cost.

The second driving module 31 is fixed between the two pillars 12. The second axial feeding unit 3 is located above the first axial feeding unit 2. The contact lens reforming processing machine is also provided with a third axial feeding unit 4. The third axial feeding unit 4 is a Z-axial feeding unit, including a third driving module 41 and a second displacement module 32 that is transmission-connected to the third driving module 41. The third displacement module 42, the first axial feed unit 2, the second axial feed unit 3 and the third axial feed unit 4 can be linear guide rails, the third driving module 41 is arranged on the second displacement module 32, and an arc generating unit 5 is arranged on the third displacement module 42, the arc generating unit 5 includes a unit body 51, a chamber is formed in the unit body 51, and an arc generating module 52 is arranged in the chamber of the unit body 51, and a hollow tube 53 is arranged below the unit body 51, the hollow tube 53 is communicated with the chamber of the unit body 51, and the hollow tube 53 is connected with a The hollow tube 53 is connected to the rotating power module 55 on the body 51, and a nozzle 54 is arranged at the bottom end of the hollow tube 53. The nozzle 54 is provided with at least one nozzle hole 541, and the nozzle hole 541 is communicated with the hollow tube 53. The orifice of the nozzle hole 541 is eccentrically arranged at the bottom of the nozzle 54. A gas supply unit 6 is also provided. The gas supply unit 6 is connected to the chamber of the unit body 51 of the arc generating unit 5 through a pipeline. The gas supply unit 6 can supply working gas without moisture. The contact lens modification processing machine is also provided with a control unit 7. The control unit 7 is a programmable controller (PLC). Please refer to Figure 4 As shown, the control unit 7 is disposed in the machine body 1, and an operation module 71 is disposed outside the machine body 1. The control unit 7 is signal-connected to its operation module 71 and the first axial feeding unit 2, the second axial feeding unit 3, the third axial feeding unit 4, the arc generating unit 5 and the gas supply unit 6;

[0038] Step B. Preparing contact lenses: placing at least one dry contact lens 8 after being demolded from a mold in at least one workpiece positioning portion 231 of a tray 23 of the contact lens reforming machine, with one side of the contact lens 8 facing upward. In the main embodiment of the present invention, a plurality of contact lenses 8 are prepared and respectively placed in a plurality of workpiece positioning portions 231 arranged in a matrix on the tray 23;

[0039] Step C. Clearing pore blockage: The operating module 71 of the contact lens reforming machine controls the control unit 7 to drive the arc generating module 52 of the arc generating unit 5 to generate an arc, and at the same time, the gas supply unit 6 introduces the moisture-free working gas into the chamber of the unit body 51 of the arc generating unit 5. After the working gas enters the chamber of the unit body 51, it is immediately dissociated into plasma by the arc generated by the arc generating module 52. Then, the plasma enters the hollow tube 53 below the unit body 51. The hollow tube 53 is driven by the rotating power module 55, so that the plasma is evenly sprayed from the spray hole 541 provided in the nozzle 54 of the rotating hollow tube 53 onto the surface of the lens 8 of the contact lens, so as to clear the impurities stuck in the breathable pores of the lens 8 of the contact lens, thereby achieving the effect of clearing the pore blockage. At the same time, the micro-burrs generated on the lens 8 during the separation process of the lens 8 of the contact lens from the mold can also be removed. Please refer to Figure 5 As shown, the control unit 7 drives the second driving module 31 of the second axial feeding unit 3 to drive the second displacement module 32 and the arc generating unit 5 assembled on the second displacement module 32 to move from left to right along the Y-axis direction, so as to complete the clearing operation of the pore blockage of the contact lens 8 in the first row on the tray 23 one by one, and then the control unit 7 drives the first driving module 21 of the first axial feeding unit 2 to drive the first displacement module 22 and the tray 23 assembled on the first displacement module 22 to move backward along the X-axis direction to move away from the arc generating unit 5, and then controls The unit 7 drives the second axial feeding unit 3 to drive the arc generating unit 5 to move from right to left to reset, and pauses the arc generating unit 5, and then drives the first axial feeding unit 2 to drive the tray 23 to move forward, so that the lenses 8 of the contact lenses in the second row on the tray 23 correspond to the position of the arc generating unit 5, and then drives the arc generating unit 5 to output plasma to clear the pores and micro-burrs blocked by the lenses 8 of the contact lenses in the second row. The above process is repeated in sequence to complete the operation of clearing the pores and micro-burrs of the lenses 8 of all the contact lenses on the tray 23;

[0040] Step D. Forming a moisturizing groove: The arc output power of the arc generating unit 5 and the working gas flow rate and the carrier gas flow rate of the gas supply unit 6 are adjusted through the operation module 71 via the control unit 7 to increase the intensity of the plasma spraying from the spray hole 541 provided on the nozzle 54 of the arc generating unit 5 onto the lens 8 of the contact lens. The hollow tube 53 is driven to rotate by the rotary power module 55 so that when the plasma is sprayed from the orifice of the eccentric spray hole 541 provided on the nozzle 54, an annular groove 92 can be etched on the surface of the lens 8 of the contact lens. Then, the control unit 7 drives the second axial feeding unit 3 and the first axial feeding unit 2 to respectively drive the arc generating unit 5 and the tray 23 to move, so as to complete the processing operation of the annular groove 92 of the lenses 8 of all the contact lenses on the tray 23;

[0041] Step E. Removing the finished product: When all the contact lenses 8 on the tray 23 are processed, the control unit 7 will pause the arc generating unit 5, and drive the first axial feeding unit 2 and the second axial feeding unit 3 to respectively drive the tray 23 and the arc generating unit 5 to reset, and then drive the third axial feeding unit 4 to drive the arc generating unit 5 to move upward along the Z-axial direction away from the tray 23, so as to remove the processed contact lenses 8 from the tray 23 and place the next batch of contact lenses 8 to be processed on the tray 23.

[0042] Accordingly, through the manufacturing method of the present invention, impurities clogging in the pores on the lens 8 of the contact lens can be easily removed to improve the oxygen permeability and hydrophilicity of the lens 8 of the contact lens. At the same time, the micro-burrs generated when the lens 8 of the contact lens is demolded can also be removed to reduce the foreign body sensation of the contact lens in contact with the cornea when the contact lens is worn, and a moisturizing contact lens with an annular groove 92 on the surface can be produced. The present invention uses a working gas that does not contain water. The working gas that does not contain water helps to maintain the surface modification stability of the lens 8 for a long time, so that the structures such as the annular groove 92 after the surface modification are not easy to be restored and disappear. The present invention has learned through many experiments that if a working gas containing water is used, a false effect will be formed. After a period of time, the structures such as the annular groove 92 will be restored and disappear, and the lens 8 will be restored to the original smooth surface without the annular groove 92.

[0043] Please also read Figures 6 to 8As shown, the moisturizing contact lens 9 of the present invention includes a lens body 91 in the shape of an arc sheet, the lens body 91 is formed with a first surface and a second surface opposite to each other, the first surface is a concave surface, and the second surface is a convex surface. The lens body 91 includes an optical zone 911, a non-optical zone 912 and an edge zone 913 from the center to the outside. The lens body 91 is formed with at least one annular groove 92 in the non-optical zone 912 of the first surface thereof. In the main embodiment of the present invention, a plurality of concentrically arranged annular grooves 92 are formed in the non-optical zone 912 of the first surface of the lens body 91, and a plurality of fine holes 93 penetrating the first surface and the second surface of the lens body 91 are formed in the non-optical zone 912 of the lens body 91.

[0044] Thus, when the moisturizing contact lens 9 of the present invention is used, the concave first surface of the lens body 91 is covered on the surface of the eyeball, and the multiple pores 93 provided on the lens body 91 are utilized to provide the moisturizing contact lens 9 with air permeability and oxygen permeability when worn. In addition, when the eyeball secretes tears, the tears can be stored in the annular groove 92 provided in the non-optical area 912, and the tears will not evaporate or be squeezed out by pressure, thereby maintaining the water content and wetness between the eyeball and the lens body 91 for a long time and achieving the effect of enhancing tear circulation. At the same time, the tear protein can be reduced to form esters on the surface of the lens body 91, so as to improve the comfort of contact lens wearing. Furthermore, since the moisturizing contact lens 9 of the present invention can store tears in the annular groove 92 to maintain the moisture between the eyeball and the lens body 91 for a long time, the eyes will not feel dry and uncomfortable due to lack of water even if worn for a long time. Therefore, there is no need to use eye drops or artificial tears to relieve dry eyes, thereby improving the convenience of wearing contact lenses. At the same time, it can also save the cost of purchasing eye drops and artificial tears, especially avoiding the use of eye drops and artificial tears containing preservatives, which may cause risks such as corneal ulcers, thereby improving the safety of wearing contact lenses.

[0045] The above-mentioned embodiments and drawings are not intended to limit the implementation of the present invention. In addition to forming an annular groove 92 on the first surface of the lens body 91, please also refer to Fig. 9 As shown, the annular groove 92 may also be formed at the non-optical area 912 of the second surface of the lens body 91. In addition, the present invention may also omit the step of clearing the pore blockage and directly form the annular groove 92 on the contact lens, or first perform the step of forming the moisturizing groove and then perform the step of clearing the pore blockage. Here, appropriate changes or modifications made by those skilled in the art should be deemed to be within the scope of protection of the present invention.

[0046] It can be seen from the above structure and implementation that the present invention has the following advantages:

[0047] 1. The manufacturing method of the moisturizing contact lens of the present invention utilizes an electric arc to dissociate the working gas into plasma, and then sprays the plasma at high speed onto the surface of the contact lens, thereby easily removing impurities blocked in the pores 93 on the lens 8 of the contact lens, and forming an annular groove 92 for storing tear liquid on the surface of the lens 8 of the contact lens. The manufacturing process is simple, fast and low-cost, and is highly competitive in the industry.

[0048] 2. The manufacturing method of the moisturizing contact lens of the present invention connects the arc generating unit 5 and the tray 23 with a plurality of axial feeding units to increase the processing range of the arc generating unit 5. In addition, the rotary power module 55 drives the nozzle 54 to rotate reciprocatingly, so that the plasma is evenly sprayed on the lens 8 of the contact lens, thereby achieving the effect of more quickly and stably removing impurities blocked in the pores 93 on the lens 8 of the contact lens and forming the annular groove 92.

[0050] 4.

[0051] 5. The method for manufacturing moisturizing contact lenses of the present invention can remove impurities that are stuck and clogged in the pores 93 of the existing contact lenses due to high-temperature demolding, thereby restoring the air permeability and oxygen permeability of the pores 93 on the contact lenses. At the same time, it can also remove the micro-burrs generated during the separation process of the contact lens 8 from the mold, thereby reducing the foreign body sensation when the contact lenses come into contact with the cornea when worn.

[0052] 6. The moisturizing contact lens of the present invention is provided with an annular groove 92 on the surface of the lens body 91, which can keep the tears in the annular groove 92, and the tears will not evaporate or be squeezed out under pressure, so as to maintain the water content and wetness between the eyeball and the lens body 91 for a long time, and can improve the circulation effect of tears. At the same time, it can reduce the formation of esters by tear protein on the contact lens, and further improve the comfort of wearing the contact lens.

[0053] 7. The moisturizing contact lens of the present invention is provided with an annular groove 92 on the surface of the lens body 91 so that tears can be stored in the annular groove 92, thereby maintaining the moisture between the eyeball and the lens body 91 for a long time and improving the circulation effect of tears. Therefore, it is not necessary to use eye drops or artificial tears to relieve dry eyes, thereby improving the convenience of wearing contact lenses.

[0054] 8. The moisturizing contact lens of the present invention is provided with an annular groove 92 on the surface of the lens body 91 so that tears can be stored in the annular groove 92 to maintain the moisture between the eyeball and the lens body 91 for a long time.
