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.
