BACKGROUND

Technical Field

The present disclosure relates to a contact lens package and a contact lens packaging method. More particularly, the present disclosure relates to a contact lens package disposed with a guard ring and a contact lens packaging method thereof.

Description of Related Art

Conventionally, package of disposable contact lenses mainly includes a plastic body and a flexible cover. The plastic body usually has a circular recess for containing a single contact lens and enough buffer liquid or contact lens solution, while the flexible cover being used to seal the circular recess for preserving the contact lens therein. Moreover, a part of the flexible cover will not be sealed with the plastic body for the user to hold and rip the flexible cover off the plastic body, such that the contact lens in the circular recess can be retrieved.

However, since the circular recess makes the package thicker, the volume of the package cannot be reduced. Moreover, the flexible cover is usually tightly sealed with the plastic body for preventing the contact lens solution from leaking. In this case, the user may rip the flexible cover with too much force, such that the contact lens and the contact lens solution may be accidentally tossed and spilled out of the package.

Further, there exists another conventional package which seals the contact lens and the buffer liquid merely with two aluminum foils. However, this aforementioned package is fragile and more likely to be damaged during transportation.

SUMMARY

According to one aspect of the present disclosure, a contact lens package including a first substrate, a contact lens, and a guard ring. The contact lens is disposed on the first substrate. The guard ring is disposed on the first substrate and surrounds the contact lens, wherein the guard ring is fixed on a side surface of the first substrate. The contact lens and the guard ring are surrounded and sealed in the first substrate.

According to one aspect of the present disclosure, a contact lens package including a first substrate, a contact lens, and a guard ring. The contact lens is disposed on a first surface of the first substrate. The guard ring is fixed on a second surface of the first substrate, and a projection of the guard ring on the first surface surrounds the contact lens. The contact lens is sealed in the first substrate.

According to one aspect of the present disclosure, a contact lens packaging method, applicable to a contact lens package array, wherein the contact lens package array includes a plurality of contact lenses, a plurality of guard rings, and a plurality of first substrates. The method includes the following steps: disposing each of the guard rings onto a first surface of each of the first substrates; placing each of the contact lenses into each of the guard rings; folding the first substrates; and hot-press sealing the contact lens package array.
