Fortnightly Contact Lenses Australia
Fortnightly contact lenses — also called two-weekly or bi-weekly lenses — are replaced every 14 days rather than daily or monthly. They occupy a practical middle ground in the contact lens market: more convenient than monthly lenses (shorter wearing period, less deposit accumulation) while more economical than daily disposables for full-time wearers. For many people, the two-week replacement cycle fits naturally into a fortnightly routine that's easy to maintain.
BuyContactsOnline.com.au stocks the Acuvue Oasys fortnightly range — the most widely prescribed fortnightly lens in Australia — at competitive prices, with same-day dispatch on weekday orders placed before 10am and free express post on orders of four or more boxes.
Fortnightly contact lenses are soft contact lenses worn daily and cleaned and stored each night, with the lens replaced after 14 days of wear. Like monthly lenses, they require a cleaning and storage routine using a multipurpose contact lens solution. Unlike monthly lenses, the shorter wearing cycle reduces the time available for protein deposits and lipids to accumulate on the lens surface — which helps maintain comfort and optical clarity closer to the level of a fresh lens for a greater proportion of the wearing period.
The two-week schedule also means wearers go through lens changes more frequently, which some find easier to keep track of than a monthly schedule.
Fortnightly Lenses at BuyContactsOnline.com.au
The fortnightly collection at BuyContactsOnline.com.au is anchored by the Acuvue Oasys range from Johnson & Johnson Vision — consistently one of the most prescribed contact lenses in Australia across both fortnightly and extended wear formats.
Acuvue Oasys with HydraLuxe Plus (Spherical)
Acuvue Oasys with HydraLuxe Plus is a fortnightly silicone hydrogel lens for wearers with myopia (short-sightedness) or hyperopia (long-sightedness). It uses HYDRACLEAR Plus technology — a moisture-rich wetting agent integrated throughout the lens material — to maintain a consistently hydrated lens surface across the full two weeks of wear.
Acuvue Oasys is particularly well regarded by wearers with higher-than-average screen exposure, air travel, or environments with low humidity, where tear evaporation and lens drying are more pronounced challenges. It is also approved for occasional extended wear of up to six nights and seven days, subject to optometrist assessment. Available in a 6-pack.
Acuvue Oasys for Astigmatism (Toric)
Acuvue Oasys for Astigmatism is a fortnightly toric lens for wearers who require astigmatism correction. It uses BLINK STABILISED Design — a four-point stabilisation system that maintains precise lens orientation through the natural movement of blinking, rather than relying on gravity weighting alone. This results in fast, reliable stabilisation even during activities involving rapid eye movement.
Like the spherical version, it incorporates HYDRACLEAR Plus technology for sustained moisture across the wearing period. Available in a 6-pack. For a broader overview of toric lens options across all brands and wearing schedules, see our toric contact lenses collection.
Acuvue Oasys Multifocal
Acuvue Oasys Multifocal is designed for wearers managing presbyopia — the gradual loss of near vision that typically develops from the mid-40s. Using Acuvue's Pupil Optimised Design Technology, the lens adapts the balance between near and distance correction based on pupil size under different lighting conditions, providing natural-feeling vision transitions at all distances.
Fortnightly contact lenses suit a specific wearing profile. They are a strong choice for full-time wearers who:
Prefer fewer lens changes than a daily schedule requires
Want a shorter replacement cycle than monthly for comfort reasons
Are prescribed Acuvue Oasys specifically and value its extended wear approvals
Find the two-week schedule easy to track and maintain
If you're a part-time wearer — wearing lenses three days a week or fewer — daily disposables are generally a more practical option, since with fortnightly lenses you are still replacing the lens on a 14-day calendar schedule regardless of how many days you actually wore them. Explore our daily contact lenses collection if a daily format suits your wearing pattern better.
For full-time wearers comparing fortnightly versus monthly schedules, our monthly contact lenses collection covers the leading monthly brands and how they compare.

Frequently Asked Questions
Do I need a prescription to order fortnightly contact lenses?
Yes. Contact lenses are classified as prescription medical devices in Australia under TGA regulations and can only be supplied with a valid prescription from a registered optometrist or ophthalmologist.
How often do I replace fortnightly contact lenses?
Fortnightly lenses are replaced every 14 days, regardless of how many days you wore them during that period. The 14-day clock starts from the first day you open the lens, not from the last day you wore it.
Can I sleep in fortnightly contact lenses?
Acuvue Oasys with HydraLuxe Plus is approved for occasional extended wear of up to six nights and seven days, subject to assessment by your optometrist. Continuous wear is not appropriate for all wearers. Speak with your optometrist before sleeping in any contact lens.
How does a 6-pack of fortnightly lenses work out?
A 6-pack provides six individual lenses. For a single eye, six lenses cover three months of wear at the fortnightly replacement schedule. Most wearers purchase two 6-packs — one for each eye — to cover three months of bilateral wear, which also meets the four-box threshold for free express post.
Can I claim fortnightly contact lenses on my health insurance?
Yes, in most cases. Contact lenses are claimable under the optical extras component of most Australian private health insurance policies. BuyContactsOnline.com.au is registered with all major Australian health funds (Provider Number 2413719K). Every order confirmation includes item numbers and a PDF invoice for easy claiming.
