When someone says “Picture this,” can you actually visualize the scene in your mind, or did you think that phrase was a metaphor? If you answered the latter, you may have aphantasia, a condition characterized by the inability to conjure mental images. This week, we explore everything on the spectrum from aphantasia to hyperphantasia and its impact on certain cognitive functions and personality traits. TLDR: Aphantasia describes the inability to visualise images in one’s mind, but this does not necessarily limit one’s imagination, creativity, or overall cognitive abilities   Links: https://theconversation.com/aphantasia-explained-some-people-cant-form-mental-pictures-162445 https://psyche.co/ideas/when-the-mind-is-dark-making-art-is-a-thrilling-way-to-see https://www.sciencedaily.com/releases/2021/06/210609115555.htm Socials: instagram.com/thelabdoctors twitter.com/thelabdoctors Credit for theme music: Fresh Time by Roa https://soundcloud.com/roa_music1031  Email: [email protected]

In this episode, we will explore the causes of amblyopia as well as up-to-date treatment options and how early intervention can make a difference.  TLDR: Lazy eye is typically treatable, especially when caught early through routine eye exams Links: https://www.healthline.com/health/lazy-eye  https://jamanetwork.com/journals/jama/fullarticle/2775449 https://linkinghub.elsevier.com/retrieve/pii/S0022-510X(22)00235-0 Socials: instagram.com/thelabdoctors twitter.com/thelabdoctors Credit for theme music: Fresh Time by Roa https://soundcloud.com/roa_music1031  Email: [email protected]

Be honest, how much time do you really spend looking at a screen every day? As technology advances, and especially in a post-pandemic world, screen time is at an all-time high. Join us as we see what the research has to say about how screen time impacts the risk of myopia (or nearsightedness), and tips on how we can protect our eyes TLDR: Experts suggest that screen time increases risk of myopia due to eye strain and prolonged near work, one helpful way to combat this is the 20-20-20 rule (Every 20 minutes, look away from your screen and at an object at least 20 feet away for 20 seconds) Links: https://www.theguardian.com/society/2021/nov/14/eyeballs-screens-vision-nearsightedness-myopia https://reviewofmm.com/what-does-science-say-about-screen-time-and-childhood-myopia/ https://www.thelancet.com/journals/landig/article/PIIS2589-7500(21)00135-7/fulltext Socials: instagram.com/thelabdoctors twitter.com/thelabdoctors Credit for theme music: Fresh Time by Roa https://soundcloud.com/roa_music1031  Email: [email protected]
