Extend the lifespan of your myopia glasses glasses with these maintenance tips!

We all know that expiration dates play an important role in protecting food safety. However, when food spoils, it can cause harm to the body.

However, the damage caused by spoiled food pales in comparison to the damage to your eyes caused by expired glasses.

Today, we'll teach you how to identify and understand the expiration date of your myopia glasses

Signs of myopia glasses  Aging

Many people with myopia often wear their myopia glasses for years after getting them, never considering replacing them until they become damaged or their vision worsens.

Little do they know that glasses have their own expiration date.

1.Lens Freshness

Optical lenses wear and tear over time. Plastic lenses absorb ultraviolet light, causing them to age and yellow. These factors affect lens transmittance.

2.Validity Period of  Myopia Glasses

With age, the refractive state of the eye changes due to varying eye conditions and severity.

Therefore, re-examination is necessary every year to year and a half.

3.adjust the angle frequently

When wearing nearsighted myopia glasses, they must be aligned with your line of sight. Otherwise, your eyes will be misaligned. Therefore, regular visits to the optician for adjustments are essential.

4.Replacing aging accessories

Like all things that depreciate, nearsighted myopia glasses accessories are not permanent. They can become damaged and loose. Therefore, it's important to replace aging accessories every three to six months.

Glass replacement cycles at different ages

Just like the naiveté of childhood, the rebelliousness of youth, the maturity of middle age, and the composure of old age.

Depending on the wearer and the material of the glasses, the replacement cycle for glasses is not absolutely fixed. The replacement cycle for different age groups varies as the body changes.

1.Children in their peak eye-use period

Glasses should be checked every three to six months after fitting. If the prescription changes by more than 50 degrees, they need to be replaced.

Children in this age group are developing physically and entering their prime learning years. Those wearing glasses during this period should have annual checkups and any changes in vision should be promptly replaced.

2.Youth

At this stage, people's bodies have matured, and the prescription of their glasses has stabilized. Myopia glasses are generally checked every one to two years, and any change in prescription by more than 100 degrees requires replacement.

3.30-40 Years Old

Some people may experience eye fatigue or discomfort due to a busy work schedule and require regular eye exams.

During this period, both their eyes and glasses should be checked at least once a year, and replacement lenses should be considered based on their vision.

4.After approximately age 60

Presbyopia reaches its maximum, and the prescription of presbyopia glasses generally stabilizes. Glasses can be replaced if damaged.

Behaviors that shorten the lifespan of glasses

1.One-handed Wearing and Removing Glasses

While wearing and removing glasses with one hand is convenient, it can easily loosen the screws on the other side of the temple, leading to them falling off and falling apart over time.

Roughly removing glasses can directly break screws or deform the temples.

2.Dry Cleaning Glasses

Glasses exposed to air for extended periods of time can accumulate fine dust on the lenses. Wiping them directly with a glasses cloth, paper towel, or sleeve can cause the friction of the dust to wear away the lenses. Cleaning with wet wipes, ultrasonic cleaners, or running water is the correct method.

3.Wearing Glasses While Bathing or Taking a Hot Spring

Many people who wear glasses wear their glasses into the shower and wash them along with them. Sometimes, they even wear their glasses while taking a hot spring bath. This is a serious mistake.

Lenses are made of a multi-layered film, which can easily peel, swell, and deform when exposed to steam or hot water.

At this point, moisture can easily penetrate the lens coating, causing it to peel and damage the lens.

4.Cleaning Glasses with Soap or Body Wash

Using acidic or alkaline soaps to clean your glasses can easily cause the lens coating to peel and damage. Furthermore, soap easily forms scum, which can lodge deep in the grooves and crevices of the frame.

Body washes and hand soaps contain oils, which not only fail to remove grease from the lenses but can also cause them to fog up after cleaning.

Besides specialized eyeglass cleaners, neutral dishwashing liquid is the best cleaning agent, and it's recommended to clean your glasses at least once a day. This not only prolongs the life of your lenses but also helps maintain clear vision.
