What should I do if the contact lenses are inappropriate? _Contact lenses_

Because many people now buy contact lenses through the Internet, the degree needs to be chosen by themselves. If you have myopia and astigmatism, you can know what type of degree is suitable for you through the corresponding table, so that subsequent wearing is also guaranteed. But what should you do if the contact lenses you really choose do not meet your degree? Before buying contact lenses, you should determine your degree. If the degree of myopia is within 300 degrees, then the contact lenses do not need to be replaced. And if there is astigmatism or high myopia, we must check a good degree table, and then choose the appropriate degree, otherwise there may be problems. Many people are buying contact lenses for the first time, and they must ensure that the degree is reasonable, otherwise it will affect the subsequent wearing effect. New contact lenses need to be adapted. After all, the degree of contact lenses and frame lenses are different, and many people are wearing contact lenses for the first time, so you must pay special attention to the adaptation process. Try to wear it for 2 hours for the first time. If you have some dizziness, it is normal, and you can usually recover on the same day. Wear it for 4 hours the next day, and so on. After that, the wearing time should not exceed 8 hours a day, so as to ensure good wearing comfort. If you have determined that your contact lenses are not correct, so the wearing effect is not very good, then it is recommended that you replace them directly, otherwise it will definitely affect our follow-up wearing effect. If you have not opened the package and purchased the contact lenses through the official website, you can also return them directly. However, contact lenses that have been opened cannot be returned. Therefore, before purchasing, we must also determine whether it can be returned or exchanged, so as not to affect our subsequent wearing.
