The Initial Progression of Physical and Perceptual Symptoms Associated With Aniseikonia.

Purpose: We aimed to evaluate the initial progression of physical and perceptual symptoms associated with wearing spectacles that produce unequal retinal image sizes in the two eyes (aniseikonia).

Methods: A within-subjects experiment (n = 20) was conducted to assess how symptoms change over one hour. Participants wore spectacles that contained a minifying lens (4%) over one eye and a plano lens over the other.

We Are Not All the Same: Implications of Heterogeneity Among Latiné/e/x/o/a, Hispanic, and Spanish Origin People.

There is great variation in the experiences of Latiné/e/x/o/a, Hispanic, and/or Spanish origin (LHS) individuals in the United States, including differences in race, ancestry, colonization histories, and immigration experiences. This essay calls readers to consider the implications of the heterogeneity of lived experiences among LHS populations, including variations in country of origin, immigration histories, time in the United States, languages spoken, and colonization histories on patient care and academia. There is power in unity when advocating for community, social, and political change, especially as it pertains to equity, diversity, and inclusion (EDI; sometimes referred to as DEI) efforts in academic institutions.

Equity and Justice in Family Medicine Clinical Care and Teaching Must Incorporate a Reproductive Justice Framework.

Since European settlement, the United States has controlled the reproduction of communities of color through tactics ranging from forced pregnancies, sterilizations, and abortions to immigration policies and policies that separate children from their families. Lesbian, gay, bisexual, transgender, queer (or questioning), asexual, intersex, and gender diverse people (LGBTQIA+) have been persecuted for sexual behavior and gender expression, and also restricted from having children. In response, women of color and LGBTQIA+ communities have organized for Reproductive Justice (RJ) and liberation.

How small changes to one eye's retinal image can transform the perceived shape of a very familiar object.

Vision can provide useful cues about the geometric properties of an object, like its size, distance, pose, and shape. But how the brain merges these properties into a complete sensory representation of a three-dimensional object is poorly understood. To address this gap, we investigated a visual illusion in which humans misperceive the shape of an object due to a small change in one eye's retinal image.
