HM Vision Plus - Eyeball Anatomy:
Our eyes are surrounded by the cornea, and the cornea is closed, so the contact lens never travels behind the eyeball.

Confusing Situations <br/>Your contact lenses disappear and you may be confused and worried about whether they fit behind your eyeballs. Whether it's because you're rubbing your eyes too hard or removing your contact lenses too hard, you may be alarmed by the sudden disappearance of your glasses. However, according to experts, it is absolutely impossible for a contact lens to travel behind the eyeball. This is because the structure of our eyes prevents this from happening.

Doctor's Advice <br/>Dr. Liang Zhongling is the director of the Ophthalmology Department of Asia University Hospital. She often encounters this situation: people rub their eyes hard and find that their contact lenses are missing, so they nervously touch their eyeballs to try to find the missing glasses. However, such behavior may cause scratches on the corneal surface and cause the feeling of foreign body rubbing. Even if the glasses are eventually found, serious damage can be caused.

Solution <br/>When your vision is blurry and you cannot find your glasses, please drop saline solution or artificial tears first, and do not rush to search with your fingers. You can move your eyes up, down, left, and right to feel which area is particularly uncomfortable. The glasses are usually in that position. You can also close your eyes, gently touch your eyelids, slowly move your eyeballs, and feel which part of your eyelids has a slight protrusion. If necessary, you can ask someone else to help you find it, or check the floor, table, sink or even clothes to make sure the glasses have not been dropped elsewhere.

If none of the above methods are able to locate your glasses, and you've confirmed that the lenses are not near your eyes, you may need to seek help from your doctor. However, most of the time, the glasses just fall out where you didn't find them instead of getting stuck in your eyes.

Tips: Care and Use of Contact Lenses <br/>In addition to the above problems, modern people often wear contact lenses for extended periods of time, which may cause the lenses to become excessively dry and difficult to fit into the eyeballs easily. This can cause eye coloration, dryness, fatigue and discomfort. Therefore, follow these tips to maintain proper contact lens use and care:

1. Follow your doctor's advice: Get regular eye exams and follow your eye doctor's recommendations for contact lens use.
2. Proper Fitting and Removal: Learn the correct way to fit and remove contact lenses. Make sure your hands are clean and follow the guidelines for cleaning and disinfecting contact lenses.
3. Observe wear time limits: Observe contact lens wear time limits and do not wear them longer than recommended. Excessive contact lens wear can lead to eye discomfort and problems.
4. Use appropriate eye drops: Use doctor-recommended artificial tears or saline solution suitable for contact lenses to keep your eyes moist.
5. Avoid contact with water: Avoid exposing contact lenses to water sources, such as swimming pools or hot tubs. This can cause contact lenses to become contaminated or damaged.
6. Replace contact lenses regularly: Replace contact lenses regularly according to your doctor's recommendations and product guidelines. Using expired contact lenses can be harmful to your eyes.

If you have any questions about the use or care of contact lenses, it is recommended to seek the advice of an eye specialist or optician.

Regardless, whether or not your contact lens has fallen behind your eye, if you experience discomfort or have vision problems, seek help from a medical professional immediately.
