Convenient and healthy disposable contact lenses
Article Tags: disposable contact lenses
Disposable contact lenses are worn for a certain period and replaced by a new pair, so that they are more convenient and healthy. According to replacement interval, contact lenses can be divided into some types: disposable lenses replaced every two weeks, frequent replacement lenses replaced monthly or quarterly and traditional lenses replaced every six months or longer. Currently, disposable lenses including the first two types have been the most popular.
Lenses replacement schedule
Contact lenses require regular cleaning so as to keep lenses clean and prevent eye infections. However, the cleaning process can not wipe out all of the deposits on them, including protein, calcium, lipids that are generated by tears. So, after a period time of use, contact lenses should be discarded.
The terms replacement schedule and wearing schedule may be confusing. Replacement schedule is the frequency in which your lenses are discarded and replaced by new ones. The replacement frequency of disposable contact lenses depends on your eyes conditions. Some people may have more proteins and lipids in their tears, while others may have allergies. For these people, the frequency should be higher.
Daily disposable contact lenses are an extreme
One fact is that if you replace contacts in a higher frequency, more health insurance your eyes will get. In this case, daily disposable contact lenses just provide the extreme protection. Also called one-day disposables, these contact lenses are discarded every night and replaced by a new one in the next morning. Daily disposable contact lenses eliminate all care such as cleaning and storing.
Lenses wearing schedule
Completely different from lens replacement schedule, lens wearing schedule refers to the removal frequency. Many people may get confused with these two terms, which actually focus on different aspects. Disposable lenses are offered in different wearing schedules: both daily wear and extended wear. Daily wear contact lenses must be removed every day at night and applied in the next morning. In other words, this type of lenses is not approved to stay in the eyes overnight. Extended wear contact lenses allow more flexible use that they can stay overnight in the eyes for more than one day. Currently, the maximum period of continuous use is 30 days. Always follow your doctor to determine the best replacement schedule and wearing schedule.
Technological improvements help lower lens prices
In the early days, contacts were expensive devices and most people thought that it was pity to discard them frequently. This concern originated from the contacts materials and designs. Nowadays, new manufacturing methods have been created and thus contact lenses can be made in greater volumes and sold still at lower prices. Furthermore, even new materials are created to produce these disposable contacts and bring down their prices.
The concern about expense
If you take conventional contact lenses, cleaning products like solutions are a necessity. This is also a part of the total expenses. Disposable contact lenses remove this cost, so that the incremental cost is relatively reduced, even if you use daily disposable contacts. In addition, disposable contacts’ price may vary between different cities, ECPs, and your specific prescriptions.
Prescription determines eligibility
The only thing that may affect your eligibility for disposable contacts is your prescription. If you have a special prescription, your options of disposable may be narrowed down. For example, you may only be permitted to wear frequent replacement contacts, rather than disposable lenses. Even if you can only wear traditional contacts, the good news is that the cleaning technology has been improved.
