What is the price-performance ratio of Youzhuo Youkeling hydrogen peroxide?

In the same price of care solution, this one is more cost-effective. Now many children will wear ok glasses. I suggest they all use this instead of rubbing it. It is very convenient to use, and children can also use it themselves. Just put it in hydrogen peroxide, then add the neutralization tablet and let it stand for two hours until the color turns green, then you can take out the contact lens and put it on.
