Ocular biometric responses to simulated polychromatic defocus.

Evidence from human studies of ocular accommodation and studies of animals reared in monochromatic conditions suggest that chromatic signals can guide ocular growth. We hypothesized that ocular biometric response in humans can be manipulated by simulating the chromatic contrast differences associated with imposition of optical defocus. The red, green, and blue (RGB) channels of an RGB movie of the natural world were individually incorporated with computational defocus to create two different movie stimuli.

Demographic Differences in Insomnia and Anxiety and the Association with Cardiovascular Risk Factors among Jordanian Healthy Adult.

Background: Prior studies showed that anxiety and insomnia are both associated with Cardiovascular Disease (CVD). There is a lack of literature related to the prevalence of insomnia and anxiety among healthy adult populations in developing countries as in Jordan, Therefore, this study aimed to examine the association between the CVD risk factors and both insomnia and anxiety among healthy adults had one or more modifiable CVD risk factors.

Materials And Methods: A cross-sectional method was used to examine the prevalence of anxiety, insomnia, and demographical and clinical association with anxiety and insomnia among 1000 Jordanian adult participants using the Hamilton Anxiety Rating Scale and the insomnia severity index.

Parenting a child with attention deficit hyperactivity disorder: Jordanian's perspectives.

Raising your child with attention deficit hyperactivity disorder (ADHD) in Jordan is a challenge due to the prevailing behavioral concerns, low availability of specialized care, and generalized feelings of social stigma. This phenomenological study involved twelve Jordanian parents of children aged 4-14 years, all diagnosed with ADHD according to DSM-IV-TR criteria. Participants were recruited through purposive sampling, and semi-structured interviews were conducted.

A Child-Friendly Wearable Device for Quantifying Environmental Risk Factors for Myopia.

Purpose: In the past few decades, the prevalence of myopia, where the eye grows too long, has increased dramatically. The visual environment appears to be critical to regulating the eye growth. Thus, it is very important to determine the properties of the environment that put children at risk for myopia.
