Soflens for Astigmatism provides a proven optical solution for patients who require consistent visual clarity to correct their astigmatism. These fortnightly lenses focus on stabilizing the lens on the eye, ensuring that the blurred or fluctuating vision often associated with astigmatism is effectively managed throughout the day.
Achieving Visual Sharpness with Lo-Torque Technology
The primary challenge for those wearing toric lenses is maintaining the correct lens orientation during movement. Bausch + Lomb addresses this through several clinical design features:
- Lo-Torque™ Design: This proprietary geometry uses prism ballasting to stabilize the lens. By weighing the lens appropriately, it remains correctly oriented even during rapid blinking or eye movement, preventing the "rotation" that causes intermittent blurriness.
- High-Hydration Hydrogel: With a 66% water content, the Alphafilcon A material creates a soft, cushioned interface between the lens and the cornea. This high water volume is particularly beneficial for initial comfort upon insertion.
- Deposit Resistance: The non-ionic nature of the hydrogel material is designed to resist the accumulation of proteins and lipids from the tear film. This helps maintain a smooth, clean lens surface for the duration of the two-week wearing cycle.
Who Should Wear Soflens for Astigmatism?
Optometrists frequently recommend Soflens for Astigmatism for patients who:
- Require specialized optical correction for astigmatism rather than standard myopia or hyperopia.
- Experience inconsistent vision or "ghosting" when using spherical lenses.
- Prefer the hygiene and convenience of a fortnightly replacement schedule over monthly alternatives.
- Have eyes that are prone to protein build-up and require a material that resists deposits.
Note: Suitability, fit, and replacement schedules must always be confirmed by your optometrist.

Common Questions About Soflens for Astigmatism
Can I sleep in Soflens for Astigmatism contact lenses?
No, Soflens for Astigmatism lenses are designed strictly for daily wear and must be removed before sleeping. Because they are manufactured from a traditional hydrogel material with a Dk/t of 32, they do not allow enough oxygen to the cornea for overnight use. Sleeping in these lenses can lead to corneal hypoxia and an increased risk of eye infections.
What is the difference between Soflens for Astigmatism and Bausch + Lomb ULTRA for Astigmatism?
The main difference lies in the material technology and breathability. Soflens for Astigmatism is an established hydrogel lens that provides high water content and stability. In contrast, Bausch + Lomb ULTRA for Astigmatism is a modern monthly silicone hydrogel lens. ULTRA features MoistureSeal™ technology and significantly higher oxygen transmissibility, making it a frequent recommendation for patients who spend long hours on digital devices or experience end-of-day dryness.
Is Soflens for Astigmatism suitable for patients who experience blurry vision when blinking?
Yes, these lenses are specifically engineered to address this issue. The Lo-Torque™ design utilizes specialized stabilization zones to ensure the lens returns to its proper position immediately after a blink. This prevents the lens from spinning out of alignment, which is the most common cause of temporary blurring for those with astigmatism.
How do I clean and store my Soflens for Astigmatism contact lenses?
To maintain eye health, you must clean and disinfect your lenses every night. Professionals recommend using a multi-purpose solution, such as Opti-Free PureMoist, to rinse and store the lenses. It is essential to rub the lenses gently during cleaning to remove surface deposits and to store them in a fresh contact lens case every night. Case replacement should occur every one to three months.
