@londoneyedoctor: Ever looked at your glasses prescription and had absolutely no idea what any of it means? 👀 Here’s a quick breakdown: 👓 SPH (Sphere): Your main prescription. A minus (−) usually means you’re short-sighted, while a plus (+) usually means you’re long-sighted. 👓 CYL (Cylinder): Indicates how much astigmatism correction you need. 👓 AXIS: The angle of your astigmatism correction, measured between 0° and 180°. 👓 ADD: Extra magnifying power for near vision, often used in reading or varifocal glasses. 👓 PD: Pupillary distance, the measurement between your pupils, used to position your lenses correctly. Save this for the next time you get your eyes tested! 👀 #GlassesPrescription #EyeDoctor #EyeHealth #Astigmatism #Eyesight
