Screens are NOT the reason kids need glasses 👀

Way more kids have fuzzy vision these days because we spend less time in outdoor light, which makes our eyeballs longer. LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Lens: A transparent biconvex structure in the eye that can change its shape to change the focal distance. - Retina: A layer at the back of the eyeball containing cells that are sensitive to light. - Fovea: A small depression in the retina where visual acuity is highest. - Myopia: A common vision condition in which distant objects are blurry. - Hyperopia: A vision condition in which nearer objects are blurry. - Emmetropization: The process by which the eye grows in order to maximize visual acuity. - Dopamine: A neurotransmitter in the retina that tells the eyeball to stop growing once it has gotten to the ideal length. - Near Work Hypothesis: The theory that the modern myopia epidemic was a result of humans spending more time looking at nearby objects.
