Facing the trouble of myopia, convenient and beautiful contact lenses have become the first choice for many people. Contact lenses are worn periodically. How can you better understand contact lenses and protect your eyes? Dr. Pan Qing, Deputy Chief Physician of the Department of Ophthalmology of Zhejiang Provincial People's Hospital, came to share with you those things about the contact lens wearing cycle.
At present, the mainstream international wearing concept is to promote "shorter and healthier". However, through clinical observation, Dr. Pan pointed out that as far as the wearing cycle of contact lenses is concerned, there still exist some misunderstandings among wearers . such as:
The reason why the annual and quarterly contact lenses can be used longer is because of the better quality.
I only wear contact lenses once in a while, so I buy them year-by-year and season-by-day in case I need them.
Q4'15 Incidence data shows that more than 1 million wearers in China ’s six contact lens consumer regions (Shanghai, Beijing, Guangzhou, Shenzhen, Hangzhou, Chengdu) still use quarterly, half-yearly or even annual contact lenses . In this regard, Dr. Pan pointed out that many research data show that long-term contact lenses can cause unnecessary damage to the eyes, and wearing contact lenses should follow the correct concept of "shorter and healthier."
Cycle evolution of contact lenses
Although the contact lens is a modern invention, its history can be traced back to the idea of "brain opening" in 1508 by artist and inventor Leonardo da Vinci. For more than 500 years, contact lenses have undergone several theoretical and research and technological innovations.
One of the latest achievements is the invention of short-cycle replacement contact lenses in the 1980s, which refers to products with replacement cycles shorter than or equal to one month (including daily, bi-weekly, and monthly). In order to distinguish this, the previous long-period contact lenses are called traditional contact lenses. Traditional contact lenses support longer wearing, which generally refers to the annual, semi-annual, and quarterly throws currently on the market.https://www.gift-package.com/
