What Are Contact Lens Durations?
With so many different coloured contact lens durations available, it is critical to understand the distinction between regular daily wear contact lenses and annual wear contact lenses. Each time period represents the recommended number of days of regular wear, beginning when the contact lens is opened and removed from its package.
Here are some of the most common names and expiration dates for coloured contact lenses found online.
- Daily contact lenses are only good for one day; once opened, they can only be used once.
- Monthly contact lenses are recommended for regular use for 30 days after they are opened.
- Quarterly contact lenses are recommended for regular use for 90 days after they are opened.
- Yearly contact lenses are intended for daily use for 365 days after they are opened.
You must take care of all maintenance and care requirements for contacts that are intended for repeated use. Our annual contacts are ideal for repeated use, but they must be kept clean to remain hygienic and comfortable to wear. Check out our guide for all the details on storing your contact lenses between uses. This is a must-read for anyone who wears contact lenses for an extended period of time.
How Long Can I Wear Daily Disposable Contact Lenses?
Daily disposable contact lenses are intended to be worn for no more than one day. These contact lenses are commonly referred to as single-use, disposable, or one-day contact lenses, and they should be prepared in the same way as any other contact lens. After one use, you can simply throw away your contact lenses, eliminating the need for contact lens aftercare and storage.
How Many Hours Per Day Can Colored Contacts Be Worn?
Colored contact lenses should be worn for no more than 8 hours per day. If you exceed this time limit, your eyes will become dry and dehydrated. Because of the lack of free flowing oxygen, contact lenses can prevent your eyes from moisturizing themselves. Although some soft contact lens materials are oxygen permeable, this will only keep your eyes hydrated and fresh for a short time.
Is The Contact Lens Duration Different From The Expiration Date?
The duration of contact lenses is the number of days that a pair of contact lenses should be worn. The stated expiration date is the last month and/or year that a contact lens is safe to open and wear. Soft coloured contact lenses can have a shelf life of up to four years from the date of manufacture. This varies from lens to lens, so always check the label before use.
What Happens If I Wear Contact Lenses Beyond Their Expiration Date Or Duration?
The duration of use begins when you open your contact lenses. A common misunderstanding is that duration refers to the number of uses, which is incorrect. If you have 30 days worth of lenses, for example, they will last exactly 30 days after opening, not 30 uses.
This is because, over time, contact lenses naturally weaken and become more prone to damage due to increased use and handling. Longer-lasting contact lenses are typically constructed of thicker and more durable materials.
The same thing happens with contact lenses that are still in their packaging, which is why it is critical not to use expired contact lenses. The solution in the lens becomes less effective, potentially affecting the lens.
Can I Sleep With My Contact Lenses On?
Although contact lenses are frequently referred to as long-lasting contact lenses, they should not be worn while sleeping. We recommend removing all of our coloured contact lenses before going to bed and storing them in a contact lens case with fresh solution.
