Eyestrain is caused by ciliary muscle spasm triggered by excessive eye use. To relieve eye fatigue, you can be treated with Heptaphyllum Digitalis Dioside Eye Drops and Compound Tropicamide Eye Drops under the guidance of your doctor. Eyestrain is usually caused by ciliary muscle spasm triggered by too much time spent in close proximity to the eyes and excessive use of electronic products such as cell phones, computers and televisions. The above factors will cause the ciliary muscle of the eye to contract for a long time and cause spasm, and the patient will have symptoms such as eye soreness, pain, blurred vision and so on. For treatment, you can order compound tropicamide eye drops under doctor’s instruction to paralyze the ciliary muscle and make it relax, so as to release the spasm. You can also order Hippophae digitalis biside eye drops to improve the blood supply to the ciliary muscle and enhance its metabolic activity, thus relieving the fatigue. However, patients who are allergic to any of the ingredients in the above medications cannot be treated with these medications. In addition, patients with glaucoma should not use compound tropicamide eye drops to relieve visual fatigue. Both of these drugs are prescription drugs and need to be used properly under the guidance of a doctor.
