"Half-year disposable colored contact lenses" refers to colored contact lenses with a discard cycle of six months. That is, after being opened and used, the theoretical design life span is about six months. However, in practice, considering various factors, it is recommended to shorten the use time:

Practical Usage Guidelines:

 From a health perspective, even with strict adherence to cleaning protocols, contact lens materials will gradually degrade over time. This includes reduced oxygen permeability and the gradual buildup of proteins, lipids, and other impurities on the lens surface. Minor scratches or deformations that are hard to detect with the naked eye may also develop. Professional recommendations generally advise discontinuing use and discarding lenses after 4-5 months of wear. If you experience frequent usage, improper care, or symptoms like eye discomfort, redness, or pain during wear, it's advisable to replace the lenses earlier than recommended.

Precautions:

Hygiene Guidelines: Always wash your hands thoroughly before putting on contact lenses to prevent bacterial or dirt contamination. As personal items, never share colored contact lenses with others to avoid cross-infection. If applying makeup, wear colored contact lenses first before applying cosmetics, and remove them before removing makeup to prevent cosmetic residue from adhering to lenses. After removing contact lenses, use a dedicated lens care solution to thoroughly clean and soak them, removing protein deposits and lipid residues. Regular use of protease tablets can also help achieve deep cleaning.

Wearing time:

 the daily wearing time should not be too long, generally recommended to be no more than 8 hours, avoid long continuous wearing, try to reduce overnight wearing, so that the eyes have enough rest time.

Special circumstances: 

When the eyes are ill (such as conjunctivitis, keratitis, etc.), it should be avoided to avoid aggravating the condition; women with cold and fever, menstruation or pregnancy, and minors should also be cautious or avoid wearing.

Product Advantages and Features: 

Compared to daily disposable lenses, semi-annual disposable colored contact lenses are more affordable per pair. Their shorter usage cycle reduces potential risks from lens aging and contamination compared to annual disposable lenses. Additionally, these semi-annual lenses offer diverse color options, patterns, and diameter choices to meet aesthetic needs. For example, smaller diameters naturally enhance eye appearance for daily commuting, while larger diameters create exaggerated eye enlargement effects suitable for special occasions.

Precautions for use Strictly follow the use period：

 do not operate the time to wear in order to save costs, so as not to cause eye problems. Wear it for no more than 8 hours a day to avoid eye fatigue. If you feel eye discomfort, such as stinging, itching, redness, etc., during wearing, you should immediately remove the lens and consult an ophthalmologist.
