Contact lenses, also known as contact lenses, can be divided into two types: soft contact lenses and hard contact lenses. Rigid contact lenses generally need to be customized in an eye hospital, and the most commonly sold lenses on the market are basically soft contact lenses. Today, let's take a look at how long soft contact lenses can last.
Unlike hard contact lenses, which are worn at night, soft contact lenses are worn during the day. In general, contact lenses should not be worn for more than 8 hours a day, and the lenses must be removed before bedtime, otherwise it will hinder corneal breathing. In particular, some low-quality lenses can cause great damage to the eyes after wearing, and are not conducive to corneal breathing, and are likely to cause symptoms such as keratitis and conjunctivitis. At the same time, contact lenses should not be worn every day, and it is best to use them alternately with frame glasses.
The shelf life of contact lenses usually has a lot to do with the material of the lens itself, and the traditional throwing type is more durable than the short-cycle throwing type. According to the use cycle, contact lenses can be divided into daily, monthly, semi-annual, annual and so on. Once contact lenses are unpacked, they must be worn according to their life cycle.
To prolong the life of your lenses, care is essential. After each wear, rub the lenses immediately, then rinse and soak with the care solution. In order to ensure the hygiene of the storage environment, the immersion care solution needs to be replaced every 2-3 days, and it must be noted that the care solution cannot be reused.
If you wear contact lenses for a long time, you need to maintain eye hygiene and protect the health of the cornea. If you find redness, pain, photophobia and other symptoms in your eyes, you must go to the hospital for consultation as soon as possible.
