How to tell if it's time to change your contact lenses

How can I tell if it's time to replace my contact lenses? This problem is ignored by many beautiful eyebrows, especially those who buy half-year-old contact lenses or annual disposable contact lenses, because it is difficult for us to judge the period of contact lenses due to the discarded bottles or boxes of contact lenses, which is often "overdue", resulting in eye infections. Xiao Ke will introduce to you next: the reason for contact lens replacement and how to judge that contact lenses should be replaced. Reasons why contact lenses need to be replaced: 1. Many people think that a pair of annual wear contact lenses can be worn for a year, but optometry studies have shown that the lifespan of annual wear soft contact lenses is only 2600 hours, and if you wear them for 10 hours a day, you can only wear them for 8 and a half months. In fact, there are problems with wearing lenses that are used for an extended period of time. Therefore, the duration of a pair of contact lenses depends on the time of use each day. However, even if the standard of care is fully followed, the protein deposits cannot be completely removed, and if possible, it is best to use frequently changed or disposable contact lenses, as shorter is healthier, and experts recommend that consumers choose lenses with a shorter cycle. Summary: The period of wearing contact lenses depends on the time of wearing them every day, so the lenses should be replaced every year to prevent problems with the lenses due to deposits. Even if worn according to the standard of care, the protein deposits cannot be completely removed, and the more they accumulate, the oxygen permeability of the lenses will deteriorate, and the corneal hypoxia will be aggravated, which will make the wearer feel uncomfortable, increase the chance of redness and infection. Several studies have shown that the longer you wear contact lenses, the higher the chance of problems with your glasses. 2. Experts do not advocate that people wear contact lenses for a long time, which will keep the cornea in a state of hypoxia for a long time. Xiao Ke suggests: people who wear contact lenses, in addition to choosing contact lenses with good oxygen permeability, wear contact lenses for no more than 12 hours a day, and it is best to control them within 8 hours, not only that, it is best to equip a pair of frames while using contact lenses, take off contact lenses immediately when you get home from work every day, put on glasses, and it is best to set aside one or two days a week to use glasses, so that the cornea can rest and delay the process of damage. How can I tell if it's time to change my contact lenses? 1. The expiration date of contact lenses must be confirmed, and the use period cannot be exceeded; 2. If the contact lens is visible to the naked eye during the use period, such as deformation, discoloration, pigmentation and damage, or blurred eyes and discomfort while wearing, you must stop using it and replace it with a new contact lens.
