As one of the oldest ophthalmic companies in the United States, Bausch & Lomb has a history dating back to 1853 and was co-founded by John Jacob Bausch and Henry Lomb. From a small optical store in New York to a multi-billion dollar market capital, Bausch & Lomb provides eye drops, contact lenses and eye surgery products in more than 100 countries.
 
Bausch & Lomb has been in China since 1987 and has three independently operated companies in China. Among them, Shandong Bausch Rohamfreda is mainly engaged in the production of ophthalmic drugs, and is the largest ophthalmic drug production base in China so far, and the main over-the-counter (OTC) eye drop brand is "Runjie".
 
There are 6 types of eye drops for different groups of people and symptoms under the Runjie brand family, according to the appearance of the bottle: Blue Runjie, Ruddy Runjie, Yellow Runjie, Xiaorunjie, White Runjie and Zirunjie. If it is daily eye fatigue and dryness, adults can choose Blue Runjie containing chondroitin sulfate, and add borneol and menthol to the excipients, which has a certain cooling feeling. Xiaorunjie contains neostigmine to relieve visual fatigue in teenagers. When the symptoms of conjunctival congestion and itching occur, it is better to choose ruddy or yellow runjie, with "zolin" and other ingredients to constrict blood vessels. If the condition is severe enough to cause inflammation or trachoma symptoms, please go to the hospital immediately and use Zirunjie as an adjunct treatment for astringent and sterilization.
 
In the Runjie family, the highest safety factor is a single dose of Bai Runjie, that is, sodium chloride eye drops, which mainly rely on sodium chloride solution to bring moisture to the ocular surface, without preservatives, and the ingredients are safe and reliable. When you feel dry eyes, using Moisturizer eye drops to help replace tears can be effective in relieving symptoms. 1 box of 10 single-dose eye drops, one at a time, the price fluctuates at 21 yuan.
