01. Why is myopia possible?
02. How can you not myopic?
03. Why is glasses worn after myopic degree still met rise?
04. What kind of lens should be chosen after myopia?
axial myopia
In myopic eyes, the focus of parallel rays refracted by the eye is in front of the retina when the eye is at rest. Studies have shown that more than 80% of myopia in children is caused by an elongated axial eye
Axial myopia: The axial growth of the eye causes the retina to move backward, and the light refracted by the eye's refractive system can only fall in front of the retina, making it difficult to see distant things.
Defocus theory of peripheral telephoto
• Myopia after monophoscope correction
• Objects in central vision are projected onto the retina, but their periphery is projected behind it.
Peripheral overcorrection can cause myopia to deepen
Good mydrimetry
