AIER Ophthalmology.

1. Professionalism. Aier Eye Hospital Group is a global ophthalmology chain, and there is no need to question its professionalism, while Dawu Smart Glasses is just a small store with low professionalism.

2. Word of mouth. Aier Eye Hospital has more than 400 Aier Eye Hospitals in China. It is a first-line ophthalmology brand in my country with a good reputation, while Dawu Smart Glasses is less well-known.
