Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a contact lens PP cup with a date counting function. Background Art

[0002] Myopia is a common visual problem, also known as nearsightedness or myopia. It is a refractive disorder. When the eyeball is too long or the curvature of the cornea and lens is too strong, it causes light to focus in front of the retina instead of directly on it, making distant objects appear blurry, while nearby objects can be seen relatively clearly. The main symptoms of myopia include blurred vision at a distance, eye fatigue, eye discomfort, etc. Myopia is generally corrected using frame glasses and contact lenses, but occupations such as medical staff and flight attendants can only use contact lenses, and they must take them to work and take them off when they go to and from work. Such occupations need to count the date of contact lenses to prevent them from expiring and causing harm to the eyes.

[0003] The current contact lens PP cup with a date counting function generally has a rotating wheel that can change numbers on the contact lens case when in use, and the date can be counted by rotating it once each time it is used. However, this active date counting method has defects. When the user is in a hurry, he will forget to count the date, which will result in the contact lenses being used after the expiration date, causing harm to the user. Utility Model Content
