contact lens case

Abstract

The invention discloses a contact lens case, which comprises a case cover and a cup body. A plate-shaped support is fixed on the inner surface of the case cover and extends toward the inner cavity of the cup; The projections that match the lenses; each projection is provided with an openable mesh cover, and the mesh cover and the projections form a cavity for placing contact lens lenses; the upper connecting part connected with the mesh cover is rotatably installed on the plate-shaped bracket On the upper surface of the net cover and the lower surface of the box cover, a defoaming net with several through holes is sleeved on the plate-shaped bracket. There is a matching hole in the middle of the defoaming net. The bracket moves up and down. The present invention can realize the function of eliminating most of the bubbles only by slightly changing the spectacle case in the prior art, has a high generalization degree, and has strong convenience and practicability.

Description

technical field [0001] The invention relates to a contact lens case, in particular to a low-cost contact lens case which can eliminate foam produced by hydrogen peroxide. Background technique [0002] Contact lenses, or contact lenses, are lenses worn on the cornea of ​​the eye to correct vision or protect the eyes. Correct wearing and daily care of contact lenses are very important to eye health. During use, contact lenses will constantly have deposits such as protein, grease, and bacteria attached to them.

Picking up contact lenses and washing them by hand will further aggravate the germ contamination, so after washing, they need to be soaked in sterilizing solution to sterilize. There are contact lens multifunctional care solutions that integrate cleaning and sterilization on the market, but the fungicides in these products will be abso...

AI Technical Summary

Problems solved by technology

In fact, the foam removal effect of this contact lens case is not obvious, because the foam formed by the hydrogen peroxide care solution, which is mixed with various catalysts, stabilizers, and water-retaining agents, is not easy to break in the air, and it is easy to follow the overflowing gas. Run to the outside of the box body, and after testing, even if the hydrogen peroxide care solution is added to a certain distance below the scale line, the care solution will flow out from the vent hole of the box body
