A second transparency. In more detail, since the accommodating tank body 11 is formed with a plurality of the optical microstructures 11c, the light passing through the accommodating tank body 11 will be refracted and diffused by the multiple optical microstructures 11c. . Furthermore, the refractive index difference between the accommodating tank 11 and the storage liquid 4 is smaller than the refractive index difference between the accommodating tank 11 and the air, and the aspect ratio of the plurality of optical microstructures 11c Therefore, the diffusion of light passing through the wetted area R1 is reduced (that is, the wetted area R1 is more conducive for light to pass through directly), and thus has the second transparency that is greater than the first transparency.

As described above, in the present embodiment, the contact lens product 100 forms a plurality of optical microscopic lenses with similar aspect ratios (eg, 0.01 to 0.1) on the inner surface 11 b of the accommodation tank 11 . structure 11c, so that the accommodation tank 11 can pass the cooperative relationship between a plurality of the optical microstructures 11c and the preservation liquid 4, so that it can achieve the difference between the first transparency and the second transparency.

The tank detection step S130: As shown in Figures 9 and 10, an optical inspection instrument 200 is used to perform a tank defect detection operation on the accommodation tank 11. The optical inspection instrument 200 in this embodiment may be an automated optical inspection (automated optical inspection, AOI) instrument. Furthermore, since the accommodating tank body 11 exhibits the first transparency (eg, translucent), the accommodating tank body 11 can partially refract the passing light, thereby making the optical detection instrument 200 can detect defects of the accommodation tank 11 more accurately.

The packaging step S150: as shown in Figures 9 and 4, place the contact lens 3 and the preservation solution 4 into the accommodation tank 11, and seal the contact lens with the sealing layer 2. The glasses 3 and the storage solution 4 are sealed in the accommodation tank 11 (such as the closed space E) to jointly form the contact lens product 100 .

Wherein, the part of the accommodation tank 11 that the preservation liquid 4 contacts is defined as the wet region R1 and has the second transparency greater than the first transparency. Furthermore, the storage liquid 4 does not fill the accommodating tank 11, so that the contact lens product 100 retains the bubble B in the accommodating tank 11, and the bubble B contacts The location of the accommodation tank 11 is defined as the drying area R2 and has the first transparency.

The lens detection step S170: As shown in FIGS. 9 and 11 , the optical detection instrument 200 is used to perform a lens defect detection operation on the contact lens 3 located in the accommodation tank 11 . Among them, since the accommodating tank body 11 exhibits the second transparency (eg, transparent), the accommodating tank body 11 can substantially completely transmit light, thereby enabling the optical detection instrument 200 to be more transparent. Defects in the contact lens 3 are accurately detected.

As mentioned above, the accommodating tank 11 detected by the detection method S100 in this embodiment can change the relationship between the first transparency and the storage liquid 4 through the cooperative relationship with the storage liquid 4 . changes between the second transparency, so that the detection method S100 can implement the tank detection step S130 on the accommodation tank 11 exhibiting the first transparency, and through the second transparency The accommodating tank 11 performs the lens inspection step S170 on the contact lens product 100, thereby facilitating all inspections using the optical inspection instrument 200.

In addition, in the lens detection step S170, the contact lens 3 is preferably completely immersed in the storage solution 4, so that the position of the contact lens 3 corresponds to all the positions of the accommodating tank 11. The wet region R1 facilitates the optical inspection instrument 200 to accurately detect defects of the contact lens 3, but the present invention is not limited thereto.
