About contact lenses 2 weeks to throw, about half a year to throw contact lenses

Once opened, the expiration date cannot be extended regardless of whether you wear it or not. There is also a correction upstairs that the color of the Johnson & Johnson contact lenses is a pigment embedded in the middle of two films, which does not come into direct contact with the eyes, and is by no means paint. So the damage to the eyes can be minimized.

But I suggest that if you can only wear it for 5 days a week, you can consider using daily disposable contacts, so that the cost of each wearing is about 20 yuan per use, and the cost may be lower than that of two weeks, because using daily disposable is not only more hygienic and convenient, but also can save money on buying cleaning liquid.

If you open it, you can't extend it.,It's recommended that you buy a daily throw-away.,There is also a 1L of the so-called paint brush??? This is really impressive... It's hard to think if you haven't seen color films or other reasons, now whether it is Japan, South Korea, Europe and the United States, color films are all laser colored (not excluding you to buy fake or domestic goods), Johnson & Johnson is like a sandwich clamp relatively safe but relatively thick, not breathable,

I know what you mean, but once it's opened, it doesn't matter if you use it or not, it's a day. Also, the color with color is definitely not good for the cornea, and its color is brushed with paint, which can easily occupy the eye. What's more, it's very fake to bring this.

It's better to go for another pair. I remember asking them when I bought it, and they said that half a year is counted from the day you open it, no matter how many times you wear it, but when the time comes, it's best to change it again. After all, it's your own eyes, so it's better to be cautious.

Personally, I don't think it's too many times to bring it.

The time can be extended appropriately.

On the question of changing the water.

Why do you say that it changes every three days?

Because the care solution will lose its effect on protecting your glasses if you don't change it for a long time, so you can keep your glasses clean.

Try to change it every three days.

But it's not very demanding.

It can be slowed down for a few days.

But don't change it every few days.

It's better to buy a new one.

The problem with the care solution is that it is not commonly used, and it is okay to change it infrequently.

Definitely not, you can only wear it once, unless you wear it for a while, wash it and bring it on, it can be soaked in the care solution, if you think that the day is wasted, you can really consider throwing it next month, half a year or year, they are cyclical longer, there is no waste of money on the day, but I think that for the sake of eye safety, it is better to wear the day! ~

It is not recommended, it may be possible twice for a short time, and don't do this for a long time each time. It's like food that has passed its expiration date.
