It will take you 10 to 20 minutes when you first start putting your contacts in. You will get better and quicker doing this over time. Make sure to rinse them when you take them out or are about to put them in. Just make sure there isn’t a ton of solution on the contact or else it won’t stick to your pupil. Never sleep with them in. The doctor will probably say that you should change your contacts every 2 to 3 weeks. In my experience, you can change your contacts every 2 to 3 months. This will save you money in the long run. I suggest getting a pair of glasses, too. Your eyes will get tired of wearing contacts, so wearing glasses can help with that.
