Testing New Bifocal Toric Contact Lenses for Astigmatism
Part of Eyes & vision clinical trials.
This study evaluates how well new bifocal contact lenses work for people over 40 who have astigmatism (blurred vision at all distances) and need reading help. You'll wear the lenses daily for about a month and share feedback via text message to help researchers understand comfort and vision quality.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Age 40 or older and currently wear toric contact lenses (lenses that correct astigmatism)
- Have astigmatism between 0.75 and 2.50 diopters in each eye
- Need reading correction (presbyopia) of +0.75 or stronger
- Willing to wear the study lenses at least 13 hours daily for 29 days with no overnight wear
- Have worn reusable silicone hydrogel toric contact lenses in the past year without major discomfort
- No history of dry eye disease, eye surgery, eye infections, or serious eye conditions

Other trials that look related to this one.
This trial tests how comfortable and clear your vision is with TOTAL30 multifocal contact lenses. If you already wear multifocal soft lenses and are 40+, you may qualify to help understand how these lenses perform in daily life.
This study tests how well MyDay contact lenses work for people over 40 who need reading help. If you wear these lenses and struggle with near vision, this trial may help you find a more comfortable solution.
This study tests two types of soft contact lenses that help with both distance and near vision. If you wear multifocal lenses or use a monovision setup, this trial may help find which lens works better for your daily activities.
This study compares multifocal contact lenses to single vision lenses and reading glasses for people over 40 who need help seeing up close. It aims to find which option provides a better experience for presbyopia (age-related blurry near vision).
This study compares two brands of multifocal contact lenses (lenses that help you see at multiple distances) in people over 40 who are currently happy with their INFUSE One-Day Multifocal lenses. Researchers want to see if switching to DAILIES TOTAL1 Multifocal lenses provides similar or better comfort and vision.
This trial tests if people who currently wear Acuvue Oasis contact lenses can switch comfortably to a new lens (P7) for astigmatism. It looks at how well the new lenses fit and how satisfied you are with them.
