2 Week Disposable Lenses
Weekly or two-weekly disposable lenses are designed to last up to a fortnight, providing a cost-effective middle-ground between daily lenses and monthly lenses. These halfway house lenses are a relatively new phenomenon in the world of contact lenses, but they are swiftly becoming popular as people find them to be a great balance. 2-week or bi-weekly lenses are a great option for people who are seeking an economical alternative to daily lenses and don’t mind the easy to manage upkeep that comes with wearing weeklies.
What are the Benefits of 2 Week Lenses?
2-week disposable lenses are designed to provide up to 14 days of clear vision when combined with a simple cleaning routine in between wears. One of the key benefits of 2-week lenses is that they are a great mix of the benefits of dailies and monthlies. Using fresh lenses each day provides a more hygienic experience and comfort, as protein deposits and debris can build up on the lens over time, but they’re also more expensive.
Monthlies are more affordable, but they require cleaning and can become uncomfortable towards the end of a whole month of wear before a fresh pair is used. With weekly lenses, there is a compromise. They are less likely to wear out as they are replaced more often than monthly lenses but they’re cheaper than daily contacts. 2-week disposable lenses are usually made from slightly thicker materials than daily lenses so they’re less likely to tear and are more durable.
In addition to better value, weeklies provide plenty of comfort as they are typically made from silicone hydrogel, so they enable your eyes to get plenty of oxygen which encourages healthy vision. Weeklies also provide versatility, as some brands can be worn as extended wear lenses which means you can wear them night and day for up to a week, if approved by your optician, without the need to remove them for cleaning. Many lenses also offer UV protection which helps to shelter the eyes from some of the sun’s damaging rays.
Caring for 2 Week Disposable Lenses
2-week lenses do require a cleaning regime to stay hygienic, in order to remove deposits on the surface of the lens and for them to stay comfortable. This includes gently rubbing the surface of the lens with some saline solution in the palm of your hand when you take them out each night and then storing them in fresh solution in a clean contact lens container until the next time you wear them. Remember to always remove your lenses with clean hands and always thoroughly wash and dry your hands before cleaning them to avoid any bacteria being transferred to the contacts.
After 14 days have passed (even if you haven’t worn them for 14 days) the lenses need to be thrown away and replaced with a fresh pair. Wearing them for any longer than this could lead to infections or discomfort, as the lens will begin to deteriorate from the first wear. While some opticians may say that using them for up to 30 days if you haven’t worn them regularly is fine, everyone’s eyes are different and the amount of protein and calcium deposits that build up on the lens can vary from person to person. For this reason, many companies suggest freshening up your lenses every two weeks to ensure they stay as hygienic as possible. Setting a recurring reminder on your phone or calendar will ensure you refresh them on a regular basis to prevent the risk of them causing infections.
Choosing 2 Week Disposable Lenses
Weekly contacts are the most appropriate option for people who wear contact lenses on a regular basis. If you’re someone who only wears lenses on occasion, such as for sport or nights out, then weeklies are likely to be a more expensive option and daily lenses would be a preferable choice. When choosing your 2 weekly lenses, look for brands that provide high levels of breathability to keep your eyes healthy and plenty of hydration, so they stay comfortable throughout the day.
Weeklies can be used to correct several vision problems, including:
Myopia and Hyperopia – Terms for short and long-sightedness, 2 weekly lenses can be used to correct myopia and hyperopia to help wearers focus on objects with greater clarity. Lenses that keep your eyes moisturised throughout the day and allow plenty of oxygen to pass through to the eye will ensure you stave off dryness and irritability by the end of the day. Acuvue Oasys lenses have Hydraclear Plus technology which means they can be worn for 24 hours a day, for up to six nights, making them an incredibly convenient option. The technology provides a wetter surface to the lens that stops them drying out too quickly for better comfort.
Astigmatism – Astigmatism is a condition that causes the cornea to have an elongated shape compared to the standard round shape than healthy eyes have. This leads to individuals having blurry vision and can also cause discomfort. Toric lenses are designed to provide a secure fit for these shaped eyes and 2 weekly contacts combine toric lenses with the convenience and hygiene of standard weeklies. Acuvue Oasys lenses for astigmatism combine the same comfort as non-toric lenses with the convenience of a 2 weekly wearing pattern. They’re made form soft, flexible material which retains moisture really well to keep the eyes comfortable and healthy.
Presbyopia – An age-related condition that causes the muscles in the eyes to lose their flexibility, presbyopia results in people struggling to adjust their focus for objects at different distances. This makes tasks like reading more difficult and causes blurred and distorted vision. Multifocal lenses, much like their varifocal glasses equivalent, make it easier for people with presbyopia to focus at different ranges with a single pair of lenses. The Acuvue Oasys lenses for presbyopia have an innovative Stereo Precision Technology that allows for a more stable and consistent vision experience. These lenses allow plenty of oxygen to pass through to the eye and also keep the eyes hydrated, meaning presbyopia sufferers won’t have to worry about wearing reading glasses and lenses.
