At the Herbert Wertheim School of Optometry & Vision Science, our goals are to explore new models and strategies for diagnosis, treatment, and prevention of ocular anomalies by conducting patient-based clinical studies/trials, as well as translational research. Our researchers are involved in clinical trials and studies that often seek participants. Current studies are described below:
Contact Lens Studies
We have various contact lens studies throughout the year, and we welcome anyone who is a current soft contact lens wearer (with or without lens-induced discomfort) to participate.
These studies typically require several visits over the course of 1 day in which clinicians will assess fit and wearing-comfort of contact lenses. Studies are updated weekly so please contact us for the most up to date information about these studies.

The CAM Study
The Childhood Activity and Myopia (CAM) Study is interested in understanding how your child’s typical indoor (e.g. device use) and outdoor activities may be related to whether or not they wear glasses.
This study is novel in that it captures information about your child’s visual environment by using two wearable devices over the span of a 2-week period. If your child has had a dilated eye exam in the last 30 days, the study visits are much more streamlined. And just to note, as a token of appreciation for your participation, a $40 Amazon gift card and a small gift will be issued.
Your child does not have to be a glasses wearer or have a history of myopia and may be able to participate if:
-They are between the ages 6 to 10 years old
-They have no history of eye disease/surgery, amblyopia, strabismus
Intermittent Exotropia Treatment Study
We are now enrolling patients with intermittent exotropia for our new study (IXT7). An intermittent exotropia is a common type of strabismus (eyeturn), where one eye turns outwards.
The Pediatric Eye Disease Investigator Group (PEDIG) is conducting this clinical trial to evaluate the effect of full-time patching versus no patching (observation). The purpose of this study is to see if full-time patching can improve distance control of IXT after 3 months of treatment.
- Randomly assigned 1:1 to one of two treatment groups:
- Patching full-time with occlusion dose monitor, OR
- No patching, observation only.
- One follow-up visit at 3 months from enrollment.
- Compensation for patients: $100 enrollment visit, $100 for completion of study visit at 3 months.
Up to 82 children to be randomized who meet the following criteria:
- 3 to <9 years of age.
- Intermittent exotropia (IXT) (near tropia does not exceed distance by 10 pd).
- No previous strabismus, intraocular, or refractive surgery (including Botox injection).
- No previous nonsurgical treatment for IXT (patching, vergence therapy, vision therapy/orthoptics, base-in prism, or deliberate overminus).
- Not allergic to adhesive patches or silicone.
The CHAPERONE Study
The CHAPERONE study, sponsored by Bausch Health, is a double-blind longitudinal study designed to investigate the use of microdosed atropine to slow the progression of nearsightedness in children.
The study duration is four years, and your child may be randomized to any one of three possible treatment arms, including a placebo group after the initial baseline visit. However, all participants are guaranteed treatment for at least 12 months of the study. If randomized, your child would come in every six months for a follow-up routine eye exam and to exchange study medication. We also reimburse for travel expenses during these visits with an Amazon gift voucher, and up to $200 of updated eyewear per year. These visits are free (and no insurance is billed for exams or eyewear) so we would encourage participants to continue to see their primary eye care provider for annual exams and to purchase eyewear.

Amblyopia or “Lazy Eye”
Amblyopia, also referred to as ‘lazy eye’, is a neuro-developmental abnormality that results in physiological alterations in the visual pathways and impaired vision in one eye, less commonly in both. Aside from refractive error, amblyopia is the most common cause of vision loss in infants and young children.
Participants will be randomly assigned to either:
Sequential Treatment
Full-time glasses first, with subsequent patching for 2 hours per day/7 days per week if there is no further improvement in amblyopic eye visual acuity with glasses alone and there is residual amblyopia; OR
Simultaneous Treatment
Full-time glasses and part-time patching for 2 hours per day/7 days per week.
Occlusion dose monitors (ODMs) will be used to record actual patch wear time during prescribed patching and follow-up visits will be every 8 weeks for 56 weeks.
Children between 3 to < 13 years old, with visual acuity in the amblyopic eye between 20/40 and 20/200. No previous treatment for amblyopia is allowed, including glasses or contact lenses.
Hypersensitivity to Light in Traumatic Brain Injury
Our researchers are investigating the mechanisms of light sensitivity in healthy adults with photalgia or Traumatic Brain Injury (TBI). Participants are compensated for their time at $40, and up to $20 for parking and transportation reimbursement.
Participation involves:
A 1-hour or less visit to the Tang Eye Center at UC Berkeley;
Behavioral testing of sensitivity to different flashing light intensities; and
Measurement of eye response while viewing flickering colored displays.
To qualify, participants must:
Be between the ages 18-65;
Have photalgia (hypersensitive to light) with; OR without having experienced a traumatic brain injury/concussion;
Be in normal health with no known eye disease or neurological conditions;
Not be pregnant; and
Have full COVID Immunizations.
Assistive Technology for Reading for People with Visual Impairment
People with low vision often use screen magnification software to read on a computer screen. Since a magnifier expands the screen content beyond the physical size of the screen (the “viewport”), it is necessary to move the content so that the portion of interest falls within the viewport. This typically requires continuous horizontal or vertical scrolling using the mouse or the trackpad, a tedious operation that can be challenging for those with poor manual dexterity.
This project will develop a new software system that relies on the user’s own gaze to control scrolling when reading with magnification. This will greatly facilitate use of a screen magnifier, and thus enable better access to onscreen information for people with low vision.
Participants will be asked to read aloud several short paragraphs from a document, or to search for and read aloud titles of pictures on a web page at a screen magnification level that they need. Participants’ gaze will be recorded using an eye tracker and how they move a computer mouse to scroll across paragraphs or to search for the titles on a web page will also be recorded.
Only one visit is required and it should take no longer than 2 hours. Participants will receive $50 for participating in the study, and transportation expenses will also be reimbursed.
Adults 18 years old or older whose vision is impaired in both eyes and need magnification to read text on a computer, tablet or smartphone are eligible. A confirmed diagnosis of eye disease that causes the vision loss will be helpful to establish eligibility.

Enhancing Vision for People with Macular Disease
People with macular disease, for example, macular degeneration, often experience difficulties with daily tasks such as reading and seeing faces. The goal of this research project is to develop methods to enhance vision for people with macular disease.
Participants will be asked to perform simple visual tasks such as detecting whether or not a spot of light is present, or identifying letters. In most cases, we will be recording the image of the retina while participants perform the tasks. The tasks themselves are simple but because we need to get multiple measurements, the testing takes about 1.5 to 2 hrs for a single session. Participants can choose whether or not to return for additional testing sessions. Participants’ time in the lab, and transportation expenses, will be reimbursed.
Adults 18 years old or older whose vision is impaired in both eyes (vision preferably within the range of 20/40 and 20/400 in the better-seeing eye) due to any form of macular disease are eligible. A confirmed diagnosis of macular disease that causes the vision loss will be helpful to establish eligibility.
