Why can't you wear expired contact lenses?
Contact lenses have a throwaway cycle. If the contact lens has been opened, the shelf life of the contact lens is calculated from the day it was opened. Contact lenses have a life cycle. The life cycle is the shelf life of contact lenses. For example, if you wear daily contact lenses, you will have to throw them away. If you wear monthly contact lenses, they will have a shelf life of one month. Even if you wear them only a few times, you will still have to throw them away. The shelf life of contact lenses is calculated from the day the lenses are taken apart, not from the number of days they have been worn.
After the shelf life of contact lenses, there will be some cases like lens aging, hardening, lens discoloration, decreased transparency, lens deformation, thickening, an increase of lens protein, and other precipitates. The microbe is easy to deposit, resulting in poor oxygen permeability. If you continue to wear it, it is easy to cause inflammation of the conjunctiva and corneal hypoxia, and the comfort level will be much worse. It is suggested to analyze the case according to your own care. Once the contact lenses have the above cases, they should be replaced in time.

Keyhole glasses are different from saddle glasses.
Glasses without nasal pads are common, usually with plastic eyewear frames and metal frames. Plastic frames without nose pads usually have a saddle-shaped nose area, therefore this type of bridge is called a saddle bridge. The keyhole is designed to touch the two points of the bridge of the nose, eliminating pressure from the top of the nose. This style is a bold fashion statement for both men and women. The design has short pads on either side of the nose, which is thought to be the most comfortable area.
