Should You Fully Correct Astigmatism? Expert Insights on Eyewear Choices
Does astigmatism require corrective lenses? Hello, doctor. Previously, you suggested going to an ophthalmologist for a refraction test with a ciliary muscle relaxant to determine if my astigmatism correction is adequate. Does this mean that the need for correction varies from per...
Dr. Wang Zhishun Reply:
Hello, for children, it is generally recommended to prescribe full correction. For adults, after an eye examination, subjective refraction may require further fine-tuning (including both sphere and cylinder adjustments), rather than simply categorizing as full correction or not.[Read More] Should You Fully Correct Astigmatism?

Will My Myopia Worsen at 30 from Increased Near Work?
Myopia will increase? Is it possible for myopia to increase at the age of 30? I've been reading a lot over the past year, which means I'm frequently focusing on near objects.
Dr. Gao Pilin Reply:
Hello, In adults, the development of myopia is usually caused by the inability of the ciliary muscle to accommodate, which is different from axial myopia commonly seen in children. Frequently focusing on nearby objects keeps the ciliary muscle in a state of tension, and over ti...[Read More] Will My Myopia Worsen at 30 from Increased Near Work?
