Features: 

VT-5E ophthalmoscope is developed on the basis of the original VT-5A ophthalmoscope technology. The high-end products for foreign markets have more mature technology level and quality than similar products. 

This product is the highest grade in material selection, technology, and assembly. It is beautiful in appearance, rich in functions, easy to handle, accurate in card position, crisp in sound, smooth and smooth in adjustment, and free from stuck feeling. The streamlined design is more aesthetic. It is an essential optometry partner for large and medium-sized optical shops and hospitals.
