Biotrue ONEday for Astigmatism by Bausch + Lomb provides a high-performance solution for those requiring daily toric lenses that maintain exceptional comfort and visual stability. These lenses are designed to mimic the natural biology of the eye.
Also available in a Biotrue ONEday for Astigmatism 30 pack.
How HyperGel™ Technology Supports the Natural Tear Film
Biotrue ONEday for Astigmatism utilizes a bio-inspired material known as Nesofilcon A. This HyperGel polymer is specifically engineered to match the 78% water content of the cornea, ensuring the lens feels natural upon application. By mimicking the lipid layer of the tear film, the material effectively prevents dehydration, allowing the lens to maintain its hydration levels and maximum moisture for up to 16 hours of continuous wear.
Consistent Orientation with Evolved Peri-Ballast Design
For patients with astigmatism, visual clarity depends on the lens remaining in a precise, stable position. Biotrue ONEday for Astigmatism features an Evolved Peri-Ballast design that utilizes a sophisticated, thinned lens profile. This advanced geometry works in harmony with the natural motion of the eyelids during blinking to keep the lens locked in position, preventing the rotation that often leads to intermittent blurring in standard toric lenses.
Reducing Glare with High-Definition™ Optics
Bausch and Lomb Biotrue Astigmatism lenses incorporate aspheric High-Definition Optics. This technical advancement is designed to actively reduce spherical aberration, which is a primary cause of halos and glare. Wearers often notice significantly sharper, crisper vision when driving at night or working in challenging, low-light environments.
Who Should Consider Biotrue ONEday for Astigmatism?
Optometrists frequently recommend Biotrue ONEday for Astigmatism for individuals who:
- Require stable, rotation-free vision to correct a confirmed astigmatic prescription.
- Experience dry-feeling eyes, particularly when working in digital environments or air-conditioned offices.
- Prefer the hygiene, convenience, and zero-maintenance routine of a daily disposable lens.
- Struggle with visual discomfort from glare or halos in dim lighting.
Note: Suitability, fit, and replacement schedules must always be confirmed by your optometrist.

Common Questions About Biotrue ONEday for Astigmatism
Is Biotrue ONEday for Astigmatism suitable for overnight wear?
No, Biotrue ONEday for Astigmatism is strictly approved for daily wear only. Manufactured from a bio-inspired HyperGel material, the lenses must be removed and discarded at the end of each day. They are not approved for sleeping or overnight use, as this can restrict oxygen flow and impact ocular health.
What is the difference between Biotrue ONEday for Astigmatism and Ultra for Astigmatism?
The primary difference lies in the replacement frequency and lens material. Biotrue ONEday for Astigmatism is a daily disposable lens made from Nesofilcon A, focusing on maximum hygiene and mimicking the eye's natural water content. In contrast, Ultra for Astigmatism is a monthly replacement lens made from silicone hydrogel (Samfilcon A), offering higher oxygen transmissibility (114 Dk/t) for those who prefer a monthly replacement cycle.
How does the stabilization in Biotrue ONEday for Astigmatism work?
Biotrue ONEday for Astigmatism ensures stable vision through its Evolved Peri-Ballast Design. This technology strategically thins the lens profile so that it settles naturally and interacts smoothly with the eyelids. Every time you blink, the lens is guided back into the correct rotational orientation, ensuring your vision remains clear even during active movement.
