Question:
Is my eyeglasses number really severe??
My eyeglasses number is -7.5, and I am nearsighted. Is this a really high number. Can you give me a website that checks the severity of each type of number
Answers:
* Low myopia usually describes myopia of −3.00 diopters or less.[4]
* Medium myopia usually describes myopia between −3.00 and −6.00 diopters.[4] Those with moderate amounts of myopia are more likely to have pigment dispersion syndrome or pigmentary glaucoma.[15]
* High myopia usually describes myopia of −6.00 or more.[4] People with high myopia are more likely to have retinal detachments[16] and primary open angle glaucoma.[17] They are also more likely to experience floaters, shadow-like shapes which appear singly or in clusters in the field of vision.[citation needed] Roughly 30% of myopes have high myopia.[9]
