Myopia and Astigmatism
Myopia astigmatism generally refers to a condition where, under relaxed accommodation, parallel light rays focus in front of the retina after passing through the ocular refractive system. Astigmatism is a common ophthalmic condition, often associated with factors such as genetics and poor eye habits.
I. Causes
1. Genetics: If both or one of the parents has astigmatism, their children have a relatively higher probability of developing it.
2. Poor Eye Habits: Prolonged use of electronic devices like mobile phones and computers, or activities like reading while lying down or squinting to see things, can lead to astigmatism.
II. Symptoms
Individuals with mild astigmatism may not experience notable discomfort, but those with severe astigmatism may suffer from blurred vision, double vision, and accompanying symptoms like headaches and nausea.
III. Treatment
For mild astigmatism, corrective measures include wearing spectacle frames or contact lenses. In more severe cases, medications like atropine eye drops or compound tropicamide eye drops, prescribed by a doctor, can be used for relief.
IV. Precautions
Patients are advised to maintain proper eye care habits, avoiding prolonged close-up viewing of electronic devices to prevent symptom aggravation. Additionally, a balanced diet rich in vitamin A sources like carrots and pig liver can supplement essential nutrients for overall eye health.
