Recruiting studies in California
- NCT06034327Recruiting
Testing a new spectacle lens for slowing myopia in kids 6–8
This study tests a special spectacle lens designed to slow the progression of nearsightedness (myopia) in children aged 6 to 8. It may be a good option for kids who are mildly to moderately nearsighted and haven't used other myopia control treatments.
Santa Ana, CaliforniaAges 6–8 - NCT05606237Recruiting
Red-light sessions to slow worsening nearsightedness
This study tests whether repeated low-level red-light therapy can slow how fast nearsightedness (myopia) gets worse in children. It may help protect future eyesight, but your child must meet specific vision and health requirements and follow the study plan.
San Francisco, CaliforniaAges 8–13 - NCT07095894RecruitingPhase 3
Glasses or eye drops for slowing nearsightedness in kids
This study tests whether special glasses or low-dose atropine eye drops can slow down worsening nearsightedness in children. It compares four groups: glasses alone, eye drops alone, both together, or a placebo (no active treatment).
Fullerton, CaliforniaAges 5–11 - NCT07721714RecruitingPhase 4
Comparing two types of laser eye surgery for nearsightedness
This trial compares two laser vision correction methods: SMILE surgery in one eye and LASIK surgery in the other eye. It is designed for people with mild to moderate nearsightedness and astigmatism to see which approach works better.
Palo Alto, CaliforniaAges 22–59 - NCT07567040RecruitingPhase 3
Delaying Nearsightedness Onset in Children
This study tests whether low-dose atropine eye drops can prevent or slow down nearsightedness in children ages 6–11 who don't yet need glasses. The goal is to keep children's vision stable and reduce their need for corrective lenses as they grow.
Berkeley, CaliforniaAges 6–11 - NCT06119243Recruiting
Kids' vision study: outdoor time and nearsightedness
This study tests if spending more time outdoors can help slow the worsening of nearsightedness (myopia) in children. It involves using special contact lenses and tracking vision changes over one year.
Berkeley, CaliforniaAges 4–14 - NCT07078799Recruiting
Comparing two types of LASIK for nearsightedness and astigmatism
This study compares two types of LASIK surgery to correct nearsightedness and astigmatism. It may help if you have healthy eyes, are 22 or older, and have a stable prescription within a certain range.
Palo Alto, CaliforniaAges 22–59 - NCT07284966Recruiting
Comfort and vision with TOTAL30 multifocal lenses
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.
San Diego, CaliforniaAges 40 years+ - NCT00221897Recruiting
Eye test study to help diagnose glaucoma
This study tests new ways to evaluate eyes to help diagnose glaucoma and related eye conditions. You may be able to join if you’re an adult with normal eye health or with concerns like myopia, glaucoma suspicion, or ocular hypertension.

What taking part in a myopia study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there myopia clinical trials in California?
- Yes. We're currently tracking 9 recruiting myopia studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a myopia study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a myopia trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
