Summary of Common Problems of Multifocal Soft Lenses for Myopia Prevention and Control

Like OK glasses, specially designed frame glasses, and low-concentration atropine, multifocal soft glasses, which were recently launched in China, are also one of the main means of myopia prevention and control, and are gaining more and more attention from parents. Dr. Jingcai has collected and sorted out the common problems of multifocal soft glasses, hoping to be helpful to all parents. As usual, this is pure popular science, no deception, no selling, please feel free to read.

Question 1: Which children are suitable for multifocal soft lenses?

Young children with low degrees

Multifocal soft lenses have a unique design and fixed defocus, which not only ensures that children can see clearly during the day, but also has a better and more stable myopia control effect. For young children, they may not be able to adapt to wearing hard OK lenses, and multifocal soft lenses may be a more suitable choice for them.

Children with myopia exceeding 600 degrees

The recommended wearing power of most OK lenses is within 600 degrees, while multifocal soft lenses can be fitted from 75 degrees to 750 degrees.

Children with mild trichiasis

Regarding inverted eyelashes, you can read another article by Dr. Jingcai, "What is the cause of inverted eyelashes in children and what are the consequences?" As a soft contact lens that directly contacts the cornea, multifocal soft lenses can reduce the friction and irritation of the eyelashes on the cornea.

Children who like sports

For children who like sports, it would be inconvenient to wear specially designed frame glasses. Multifocal soft lenses are comfortable to wear and do not affect their participation in sports activities.

Question 2: Can I purchase and use it on my own?

No. Multifocal soft lenses are medical devices used for myopia prevention and control. They are not ordinary contact lenses and need to be examined and fitted by a doctor before use.

Question 3: What should I pay attention to when wearing it daily?

Different from OK lenses, multifocal soft lenses are meant to be worn during the day. They must be removed before going to bed at night and should not be worn to sleep or overnight.

For children who are wearing the lenses for the first time, you can gradually increase the wearing time every day to allow them to adapt. For example, 4 hours on the first day, 6 hours on the second day, 8 hours on the third day, 10 hours on the fourth day, and gradually increase to full-day wearing (12-15 hours);

When wearing glasses, pay attention to distinguish between left and right eyes, front and back;

Remember to wash your hands before taking it off;

Do not wear defocused soft lenses when swimming, bathing, or taking a sauna;

Do not take a nap with glasses for more than 1 hour;

The lenses currently on the market are daily disposable, which means that the lenses are discarded on the same day after use and cannot be used the next day.

Question 4: When should I stop wearing them?

If your child has red eyes, increased eye discharge, eye pain, photophobia, etc., he or she should stop wearing the glasses and seek medical attention immediately;

You can also stop wearing it if you have a severe cold or fever;

Question 5: Do I need a follow-up visit?

Like other myopia prevention and control methods, it is critical to have a follow-up visit every 3 months during the use of multifocal soft lenses. During the follow-up visit, the three indicators of myopia degree, visual acuity, and axial length should be focused on. The "Health Record" function of the Tejingcai platform can help you record these data conveniently and quickly. Reviewing these data with the doctor during subsequent follow-up visits will greatly improve the communication efficiency between parents and doctors;

Question 6: How to ensure the myopia prevention and control effectiveness of multifocal soft lenses?

Standard wear, at least 10 hours a day;

Timely follow-up visits;

Other factors that lead to the progression of myopia should still be paid attention to, such as the time spent using the eyes at close range, the standardization of reading and writing postures, the lighting conditions in the reading and writing environment, whether there is enough sleep, and whether there is enough time spent outdoors in the sun every day.
