The lifetime of contact lens

Traditional type: the replacement cycle is more than 3 months, not more than 1 year, that is, we say we abandon after one season, and we can abandon after half a year and a year.

Frequent-change type: the replacement cycle is more than 2 weeks, not more than 3 months, that is, we often say that we throw them after 1 month or two weeks.

Abandoned type: as a one-time use, common for the day use.

Contact lenses, like food, have an expiration date. For example, the shelf life of daily contact lenses is one day (after it is opened), and can not exceed this time. And the life span of a pair of glasses depends on how long you use them each day. Although different lens materials determine different wear times, we recommend that soft lenses should not be worn for more than 8 hours per day (do not wear soft contact lenses to sleep). Traditional contact lenses can be used for a long time, so the lens is easy to produce protein-lipid deposition, and then they are easy to cause eye surface inflammation and hypoxia reaction. If conditions permit, it is recommended to choose the frequent-change type and discard type, the shorter the cycle, the healthier.


Is it a good idea to buy glasses online?

If the product is purchased from a reputable and trusted retailer, buying glasses online is just as safe as buying any other product online. Buying custom-made products, such as 'prescription glasses' online, is a bit more complicated than buying regular 'ready-made' glasses. All uploaded prescription glasses orders are reviewed and notified when serious errors are found in the prescription. All prescription glasses to be shipped are also carefully checked by quality control personnel to ensure that the glasses match the required prescription to the highest standard.



The frame needs to match the face shape.

Based on the basic principle of modifying the face shape, avoid wearing frames that are too similar to your face shape as far as possible, so as not to cause the lines of the face to be overly emphasized. The combination of the glasses and the face shape determines whether the glasses are suitable for you or not. Usually, we use the shape of the glasses to modify the shortcomings of the face shape. For example, for a man with a square face, round glasses are more suitable.

How to Know If You Need Bifocal Glasses?

As you get older, you will find that is more and more difficult to read or focus on things that are really close up. This is called presbyopia and it is a common eye condition among older people.

How to know if you need bifocal glasses? If you find yourself squinting at the text that once was easy to read or your vision is blurry, you may need to see an eye doctor. In this situation, you may need bifocal glasses to correct your eyes.

If you currently wear glasses but see print more clearly when you remove them, it is a sign that you may need bifocal glasses in the future.

To know if you need bifocal glasses exactly, check your eyes by an optometrist or ophthalmologist.


Wearing glasses correctly will not get deeper degrees

The development of myopia is not directly related to wearing glasses. Patients with myopia wear suitable glasses and pay attention to eye hygiene, and the degree of myopia will stabilize at a certain level. But if you think that with glasses, everything will be fine. If you don't pay attention to eye hygiene in normal times, if you continue to keep your eyes in a state of fatigue for a long time, it will lead to vision loss and deepening of myopia. In addition, wearing improper glasses such as no optometry or inaccurate optometry, too large power, will increase the burden on the eyes, reduce vision and deepen the power. For some people with high myopia (more than 600 degrees), although they insist on wearing glasses, the degree will still deepen, accompanied by changes in the fundus, which is medically called pathological myopia. This deepening of myopia is related to the degree of myopia and family and has nothing to do with wearing glasses.



Should I wear driving glasses at night?

In fact, it is not safe to use any colored lenses while driving. You might consider how much color plays in your average driving experience. Red, yellow, green, orange traffic signs, and other vital signs are designed to remind you to pay attention to safety signals and directions while driving. However, if you see everything turn yellow, you may miss a sign and end up making the wrong decision at the traffic light, or worse, an accident.

Another disadvantage is that they do not have a prescription. If you are looking for a pair of standard night driving glasses on the market, you will find that most of them are standard over-the-counter glasses. To have night-driving glasses that can correct vision, you must customize them in an optical shop, and the price is much higher. Under the hype of the night vision feature, you can expect the cost of prescription night driving glasses to be too high.
