(Review) Elementary school child's vision test, strabismus test, color blindness test review

I felt that my first child’s eyesight was really poor around the second grade.

I went to the ophthalmology clinic, had my eyesight tested, and started wearing glasses.

However, since the child finds glasses uncomfortable, they don't wear them well at school and only wear them at home when told to, so their eyesight gradually worsened.

 

One day, around last year, my child was watching TV at an angle. At first, I just thought he was sitting improperly and kept nagging him to sit correctly. However, during a family gathering where we were playing Nintendo games with cousins, my husband mentioned that my son's eye direction seemed strange.

And after looking around the internet, they said it looks like strabismus...;;;

So, I decided to go to a larger hospital that also provides strabismus correction, instead of the local ophthalmology clinic I used to visit.

 

I went to Seoul Samsung Eye Clinic in Sejong City and had my pupils dilated for an examination. I thought my husband and I had exotropia, but it turns out I have esotropia, although it's not severe and is related to my vision.

My eyesight has deteriorated so much...;;

My son loves books so much that he often reads them in dark places, reads them while lying face down, and even looks at them while eating...

I think it might also be affected by looking at it with an improper posture.

Playing games for 30 minutes three days a week and watching 30-minute videos on the other three days without gaming might also be problematic.

Still, to get along with fourth-grade elementary school children, you shouldn't just block games.

You can't really call it reading, you know...

 

So, I repeatedly told him to get his glasses adjusted to his vision that day and to make wearing glasses a regular part of his daily life.

 

But this year, while looking at a picture with multiple colors mixed together, I realized I couldn't distinguish the orange from the green and couldn't tell the colors apart... Oh. My. God!!! ㅠㅠ

Are you color blind? No, it's just that individual colors can be distinguished, but when mixed together, red-green color blindness makes it difficult to tell them apart...

This is largely due to genetic causes... It seems that either I or my husband's ancestors have red-green color blindness.ㅠㅠ

 

First, I need to get tested...

I visited Seoul Samsung Eye Clinic again recently.

It was time to redo the vision test, so I received a reminder for my regular check-up...

 

It is one of the very large ophthalmology clinics in Sejong.

Various tests and surgeries are possible.

The director is also a doctor, right?

 

Sigh... I feel sorry for my son's back view.

It's not my fault, but I have color blindness... ㅠㅠ

 

I receive a waiting number and wait.

When I went after work, only the director was there.

 

The view of the main gate and the reception desk..

 

This is the examination room.

First, I conducted the child's vision test.

 

And next to the eye exam room, there's a place where you can do color blindness tests.

 

First, proceed with the vision test...

The news that it has fallen two more levels... so sad ㅠㅠ

 

An elementary school child is wearing lenses next to this laboratory.

I am practicing.

Perhaps they are practicing with dream lenses.

 

The results weren't very clear, but I am undergoing a color vision deficiency test. The color vision test is similar to the color blindness test I took in elementary school, where you read numbers or letters within various colors...

As expected, distinguishing between red and green is not easy...

 

The child tries to read and find out if there is a problem with themselves...

The test doctor says that this is not about right or wrong, but about checking if you have any problems, so if you don't know, just say you don't know.

I also told them it's okay and to just say they can't see it if they can't see it, and I comforted them. ㅠㅠ

 

The test above is number finding, and the one below is pathfinding..

The monitor screen has turned white..

 

And I met with the doctor to hear the test results. First of all, my vision is not even 0.1, but 0.08... Sigh...

And they said their strabismus is okay. They are not worried about their strabismus right now.

And there is red-green color blindness.

They distinguish solo colors, but when the colors are mixed, it's a bit difficult to differentiate between red and green, but there is no problem in daily life... They say that this is largely genetic and there is no specific treatment method.

I also know about this...

I told the child that Mark Zuckerberg, the person who created Facebook, a social networking service that connects people worldwide, is also red-green color blind, which is why Facebook's icon is blue.

It's not a problem at all, so don't worry.

 

I went to the optical shop with my vision test results to get my lenses adjusted again, and I came home. Haha

 

 

I'll tell you once by searching the internet about what color blindness is and what it involves.

---Yonsei Bareun Eye Clinic Blog Excerpt---

When color vision deficiency occurs, people wonder whether they are completely unable to distinguish colors or if it becomes a hindrance in social life or work.

Generally, the prevalence of color vision deficiency is about 10%, so first, let's understand how humans distinguish colors.

The eye has a structure called the retina, which functions like film in a camera, and it contains visual cells.

When an image of an object is projected onto the retina, it becomes the most direct stimulus, allowing visual information to be received.

 

In the retina, there are cone cells and rod cells, and among them, the cone cells are responsible for sensing and distinguishing colors.

These cone cells have three different types, each containing a pigment that is particularly sensitive to red, green, or blue light.

When light reflects off a colored object and enters the eye, the color is perceived based on the proportions of red, green, and blue present in the object's color.

The three types of cone cells are stimulated differently, resulting in the perception of a single color.

 

It is possible to see and distinguish various colors depending on how much the cone cells are stimulated.

At this time, what is called color vision deficiency refers to the inability to distinguish or perceive certain colors well.

It mainly appears when there is an abnormality in cone cells, including red color deficiency, green color deficiency, and blue color deficiency.

They are classified as color vision deficiency and color blindness to this extent, which can occur congenitally or acquired later in life.

 

The primary cause of congenital reasons is mainly genetics, while acquired causes include red-green or blue-yellow color vision deficiencies, such as cone cell dystrophy.

It can be caused by retinal pigment epithelium degeneration, glaucoma, diabetic retinopathy, and other conditions.

Color blindness means that, like normal people, they have all three types of cone cells: red, green, and blue.

However, when one or more cone cells are weakened and the relevant color is mixed with other colors, it cannot be distinguished.

Most color vision deficiencies in patients are red-green deficiencies, and blue deficiencies are very rare, but even with weakened function, they can still perceive red or green.

 

When there are only red and green lights like traffic signals, or just one of them, you can recognize the corresponding color.

However, when red and green are present together, people with red color blindness can distinguish green because the red appears darker and more intense.

People with green color blindness need the green to be more intense than the red in order to distinguish between the colors.

If you have doubts, it is helpful to undergo color blindness tests and color vision deficiency examinations to receive an accurate diagnosis.

 

Color blindness occurs when one type of cone cell among the three types—red, green, or blue—is missing.

Because of this, all colors are perceived with only two colors, but those with red-green color blindness cannot see red at all.

If there are no red cone cells, then when viewing red or green, only green cone cells are stimulated, causing the brain to perceive red and green as the same color.

Color blindness without green cone cells means that the person cannot perceive green at all and perceives red and green as the same color when viewing red and green.

Even when the red light is turned on, it does not appear red, but with slight color vision deficiency, red, green, and blue can be distinguished.

Color blindness test

​

1. It is difficult to distinguish the colors of traffic lights.

2. I can't tell if the meat is cooked properly.

3. I don't know the extent of the skin burn.

4. It is difficult to check whether vegetables or fruits have stripes or spots.

5. When there are red petals like roses and green leaves, it is difficult to distinguish between the flower and the leaves.

6. The colors on the subway map all look similar.

I hope this information will be helpful to someone...

 

This is our son's review of his vision test, strabismus test, and color blindness test.

Although color blindness cannot be helped, I must take good care to prevent my vision from getting worse. ㅠㅠ
