Patients require daily disposable lenses that they can wear all day and use at work, where they often use screens for many hours, and consequently spend much of the day blinking less frequently leading to tear film evaporation^11^.

Biotrue ONEday for Astigmatism daily disposable contact lenses with Surface Active Technology maintain 98% of their moisture for up to 16 hours and provide comfortable vision for your astigmatic patients^1,2^. Biotrue ONEday for Astigmatism is designed to control spherical aberration in both the cylinder and sphere meridians of the lens, helping to reduce halos and glare^3^. 

Visual clarity throughout the day for your patients^3,10^

  • The world-class engineers and scientists team behind Biotrue ONEday have used aspheric optics to provide spherical aberration control, something unique to Bausch + Lomb^3^
  • A study of 414 people demonstrated that Biotrue ONEday lenses deliver consistently crisp, clear vision without blurriness or fluctuations throughout the day^9^  
  • The prism-free peri-ballast stabilisation design helps to ensure stability on wearing^10^

Exceptional all day moisture and comfort^2,7,8^

  • The Biotrue ONEday lenses are biocompatible and have been shown to maintain a healthy tear film which helps provide comfort
  • Biotrue ONEday contact lenses contain 78% water and possess a dehydration barrier that means that 98% of the lens moisture is maintained for up to 16 hours^1^ – meaning that the lens starts and ends the day with more moisture than other daily disposables and is therefore less likely to change shape causing blurriness or fluctuation in vision
  • Biotrue ONEday lenses have an oxygen transmission Dk/t level of 42, which is above the level of required for the cornea to remain healthy when the eye is open 

Science & Technology

Advanced Technology for today's astigmatic patients 

Provide your patients with consistently clear vision and comfort throughout the day^2^. Prism-free peri-ballast stabilisation design helps to ensure stability and comfort on wearing^10^.



Surface Active Technology

Biotrue ONEday contact lens material possesses an effective dehydration barrier that maintains 98% of its moisture for up to 16 hours^1^.


  • PVP (hydrophilic polyvinylpyrrolidone) allows for a high water lens that is 78% water^10^ 
  • Poloxamer 407, a Surface Active Macromer, forms a dehydration barrier that helps Biotrue ONEday start and end the day with more moisture than leading daily disposables^1^
  • Like the lipid layer of the tear film, Biotrue ONEday provides smooth optical surface and resists dehydration^1^

1. Twenty-two subjects participated in a randomized, double-masked, contralateral eye study to evaluate water loss of Biotrue® ONE Day and 1-Day ACUVUE Moist contact lenses. After 4, 8, 12, and 16 hours of wear, lenses were removed and immediately weighed (wet weight). The lenses were then completely dried and reweighed (dry weight). The percent water loss was then calculated for each lens from the wet and dry weights.

2. Results from a 7-investigator, multi-site study of Biotrue ONEday for Astigmatism on 126 current non-daily disposable toric soft contact lens wearers. Lenses were worn on a daily wear basis for 1 week. Performance was rated using a 6-point agree/disagree scale and statistical analysis was performed to assess whether significantly more patients agreed than disagreed

* WARNING: UV-absorbing contact lenses are NOT substitutes for protective UV-absorbing eyewear, such as UV-absorbing goggles or sunglasses, because they do not completely cover the eye and surrounding area. The effectiveness of wearing UV-absorbing contact lenses in preventing or reducing the incidence of ocular disorders associated with exposure to UV light has not been established at this time. You should continue to use UV-absorbing eyewear as directed. NOTE: Long-term exposure to UV radiation is one of the risk factors associated with cataracts. Exposure is based on a number of factors such as environmental conditions (altitude, geography, cloud cover) and personal factors (extent and nature of outdoor activities). UV-blocking contact lenses help provide protection against harmful UV radiation. However, clinical studies have not been done to demonstrate that wearing UV-blocking contact lenses reduces the risk of developing cataracts or other eye disorders.
