We are investigating the correlation between the latest colour vision tests and Royal Canadian Air Force pilot colour-related tasks. In each session, your colour vision will be assessed with a variety of different tests and you will perform colour-related pilot tasks using simulated displays.

Eligibility: Participants between 16 and 50 years old who have normal colour vision, colour vision deficiencies, who suspect that they have colour vision, and individuals who are curious about their colour vision.ÌýÌý

Compensation: There will be two sessions separated by approximately 2 weeks, about 2.5-3 hours per session.

After completing the first session, you will receive $60 and $70 after completing the second session.

We're looking for participants who have dry eyes, neuropathic pain, neurotrophic keratopathy, or healthy individuals free of ocular disease. You will undergo a brief examination of the front of the eye, and some procedures will involve touching the eye surface. You will complete symptom questionnaires, and a sample of your tears will be collected.Ìý

Eligibility: Adults (>18/yo) who experience stinging, burning, tingling, shocking, throbbing, or stabbing pain in the eyes or those who been diagnosed with neurotrophic keratopathy. We're also recruiting control participants who have no known ocular diseases and do not wear contact lenses.

Time commitment:ÌýOne 60-minute session held in person.Ìý

Compensation:ÌýÌýParticipants will receive $20.00 in renumeration and up to $7.00 in reimbursement for parking or public transit.

We are researching the impact of childhood eye conditions such as lazy eye (amblyopia) on everyday life. This study is important because children and adults with childhood eye conditions may have different eye movements, read slowly, or have motor issues. We want to better understand the causes of these issues, which may lead to the development of early interventions and treatments. This study's primary investigator is Dr. Krista Kelly.

Eligibility: Children and adults 3 to <40 years of age diagnosed with a childhood eye condition (amblyopia, strabismus, anisometropia, cataract). We are also recruiting control participants with no vision conditions other than wearing glasses.

Time commitment: One in-person visit at the School of Optometry & Vision Science, approximately 60 minutes with an optional second visit later. Participants will receive a $50 Walmart gift card per visit at each visit in appreciation of their time, plus reimbursement for parking.

To participate, please contact Krista Kelly at krista.kelly@uwaterloo.ca or call 519-888-4567 ext 41330.

We are looking for adults diagnosed with macular degeneration for a study which examines whether reading can be improved through a combination of practice and the use of a safe, well-established technique for temporarily changing brain function called non-invasive brain stimulation. It is important to note that we cannot guarantee that you will personally experience any visual benefits. However, we are performing this study because we believe it might hold promise for future treatments and interventions.

Participants will be asked to read words on a computer screen for 9 study sessions spaced out over a period of 2 to 3 months.

Eligibility: Adults diagnosed with macular degeneration. Participants must not have any additional eye conditions (previous cataract surgery is acceptable), should not be undergoing eye-based injections, and must be eligible for non-invasive brain stimulation (researchers will screen for this).

Time commitment: Attend 9 visits (2 hours per visit) over the course of approximately 2 to 3 months. You will be given $20 per session in appreciation for your time. Transportation will be provided at no cost to you. However, if you have a driver, we can provide them with a parking voucher to cover any parking expenses.Ìý

To participate, please contact Melanie Mungalsingh at mamungal@uwaterloo.ca. Alternatively, you can call 519-888-4567 ext. 38651. If necessary, please leave a message so we can get back to you as soon as possible.

We are seeking adults to participate in a study to investigate the effects of coloured light adaptation in myopic and non-myopic eyes. The study aims to understand whether coloured light adaptation alters responses. The participant's vision will be measured with a standard eye chart along with their refractive error. Electroretinography (ERG) measurements will be recorded using a skin sensor on the lower eyelid before light adaptation for 20 minutes followed by another ERG measurement after.

Eligibility: Healthy adults (18 to 30 years old) who need corrective lenses (glasses or contact lenses) for myopia in one or both eyes or see well without correction. This study has been reviewed and received ethics clearance through the University.

Time commitment: Two in-person 1.5 hr visits. Eligible participants will receive $40 per visit.Ìý
