Factors that cause eye pain when wearing orthokeratology lenses

People who wear glasses frequently know that wearing glasses for a long time can cause some uncomfortable symptoms. This situation mostly occurs because the care solution on the lenses is not cleaned during the cleaning process. Also, the glasses have been used for too long and scratches appear on them, causing eye discomfort. Wearing glasses in this state for a long time can easily cause eye discomfort and pain, so be sure to check your glasses before wearing them.

I divide these factors into three stages according to the time of wearing glasses:

1. When you first put on glasses

It is common to experience pain when wearing glasses, which can be relieved by taking off the lenses. It is obvious that this situation is mainly caused by wearing glasses. I found in my work that pain occurs when you first wear glasses. There are two main reasons:

The lens care solution is not rinsed clean

The care solution on the lenses is not rinsed off, which is common in families who have just started wearing lenses. This is caused by insufficient preparation of cold boiled water or lack of expertise in wearing and care. (Some people will feel a certain degree of irritation after the care solution enters the eyes) So I will remind my users to prepare more cold boiled water in advance to rinse off the residual care solution on the lenses, and the eyes will no longer hurt.

Scratches on the lens

Generally, scratches will appear on the lenses after half a year or a year of use, and occasionally some new users may also have scratches. The main causes of scratches on lenses are long fingernails or lenses that have been dropped on the ground. When there are scratches on the lenses, your eyes will feel uncomfortable when you wear them.

Of course, some smaller scratches will not cause eye pain. Only larger scratches will cause eye pain. Some minor scratches can be sent back to the factory for polishing as long as they do not affect the wearing effect. However, if the scratches are too large, the only option is to replace the lenses.

2. When sleeping at night

Wearing glasses at night is fine, but after wearing them for a while (usually a few hours), children will cry at night and say their eyes hurt. There are also two factors at this stage:

The lens is not clean and has sediment

This situation usually occurs after the lenses have been used for a period of time. Because the lenses are not cleaned vigorously enough every morning, a lot of protein secreted by the eyes will precipitate on the lenses, and some even have a white circle. In this case, the air permeability of the lenses will decrease, and when children wear glasses for a few hours, it will cause corneal hypoxia, resulting in pain.

The complete solution to this problem is to clean the lenses. Of course, ordinary care solutions may not be able to clean them thoroughly. Parents can take the lenses to a fitting hospital and use advanced cleaning solutions to clean them, or send the lenses to the manufacturer for processing. If none of them can clean them, then it is recommended to replace the lenses.

The lens is misaligned

Another situation is that when the child enters deep sleep, there is a rapid eye movement period, and the lenses are dislocated. At this time, just take off the lenses.

3. When taking out the lenses in the morning

Eye pain after getting up in the morning is rare and usually occurs when it is difficult to remove the lens. After wearing the lenses for a night, they will sometimes be fixed on the cornea. When the lenses are removed without any mobility, the eyes will feel painful due to excessive force. At this time, observe whether the child's eyes are congested. If so, you can use some anti-inflammatory drugs appropriately. In order to protect the cornea, you can also use some sodium hyaluronate eye drops appropriately. If there is no redness or swelling, the pain will be relieved in a few minutes or ten minutes, and no special treatment is required.

You may not encounter the above situations. But if you know in advance the factors that cause eye pain when wearing orthokeratology lenses, you can avoid such problems. If parents have any questions during use, please call our fitting doctor in time! It is a good way to remind users of orthokeratology lenses to have regular checkups to ensure safety and effectiveness.
