Researchers at London South Bank University and Institute of Optometry are seeking participants for a clinical study that examines whether vision or ocular comfort changes during the menstrual cycle.

Women over the age of 18 who have regular periods are invited to take part in the trial, which involves filling out an online questionnaire at three points over the course of their monthly cycle as well as an optional online vision test.

Exclusion criteria are listed on the study website – with women who are diabetic, pregnant or breastfeeding, or taking a progestogen contraceptive pill, included within the list of those ineligible to take part.

The three points are determined by information provided during the initial sign-up process, with participants automatically notified of when it is time to complete the next questionnaire.

The online questionnaire takes no longer than 10 minutes to complete, while an additional online vision test will also take around 10 minutes.

The researchers aim to publish the outcomes of the study in the first half of 2023.
