What should I pay attention to when buying contact lenses? _Contact lenses_

As long as the quality of the contact lenses is good and the diameter of the lenses meets our needs, the effect of wearing them is actually quite good. Many people need to wear contact lenses for a long time, so we must buy through such a large-scale platform. In this way, if you get a regular brand of contact lenses, at least your daily wearing is more secure. But there are a few things to keep in mind when buying contact lenses. Note 1, regular brand is the key No matter what type of contact lenses you want to buy, you should always make sure that they are of a regular brand, so as to ensure that there will be no problems with subsequent wearing. And everyone should also know that contact lenses are basically bought through the Internet, so we must buy them through formal channels. They all cooperate directly with contact lenses of various brands, so they can be guaranteed to be genuine, and such a high-quality platform is definitely worthy of our trust. Matters needing attention 2, determine the situation of the base arc Many people buy contact lenses is still very easy, just come directly to buy, and determine the degree. But in fact, everyone didn't pay attention to their base arcs, and even the base arcs were marked on the Internet, but no one paid attention to them. In fact, before you wear glasses, you should go to the hospital for optometry. If you have not noticed the condition of the base arc before, you should also determine it in advance. As long as you have a clear base arc, you won't have a slippery problem when you wear contact lenses. Note 3, the usage cycle There are many contact lenses that are thrown daily and biweekly, but there are also contact lenses that are thrown semi-annually and annually, so we should definitely determine the usage cycle of the contact lenses we buy. If it is an annual disposable contact lens, if it is really to be worn for a long time, it is recommended that it should be replaced in about half a year, otherwise there will be more bacterial growth, which will have a great impact on our eyes. So be sure to pay attention to the use cycle, and do not use some contact lenses that are about to expire.
