A 4-week-old child with 175 degrees of myopia needs to first determine if it is true myopia or pseudomyopia. True myopia can be corrected with eyeglasses, while pseudomyopia can be alleviated by resting the eyes.
A 4-year-old child with 175 degrees of myopia needs to be further examined by dilated optometry to determine the type of myopia, which in most cases is due to pseudomyopia and in a few cases is due to true myopia.
For pseudomyopia, there is no need to wear eyeglasses or other means of correction, but can be eliminated by paying attention to good eye protection, avoiding visual fatigue, and resting the eyes more often.
For true myopia, the child usually needs glasses to correct it.
It is recommended to bring the child to the ophthalmology department of the hospital for a detailed examination by the doctor to confirm the diagnosis and guide the treatment.
