Cataract is a disease that because the lens of the eye becomes cloudy by aging, vision becomes blurry or things are seen doubly or triply.
The ratio that people with cataract cause a traffic accident is about 2.5 times more than people with normal vision. In the worst case, it causes loss of the eyesight.
Let’s check the risk of cataract Part-I
Which Japanese characters are written in Fig. 1, たどれ or たちどまれ?
The answer is たちどまれ.
If you can only see たどれ, you may have initial cataract.
Cataract often makes the lens tune yellow. Cataract is the condition seeing things through a yellow filter, so it is difficult to see yellow and it is also difficult to see blue because it becomes black (Fig. 2).
Progression of cataract makes it difficult to distinguish whether the fire of the stove is on or off (Fig. 3). That causes accidents like getting burned or burning clothes.

Which Japanese characters are written in Fig. 4, おしりor おとしより?
The answers is おとしより.
In some symptoms of cataract, things look like white. That makes difficult to see thin colors or notice a slight difference in level, causing falls.
The above 2 tests are for the cataract that the center of the eye is cloudy, but there is a cataract that the eye is cloudy in spots (Fig. 5). In this case, the center of the eye is relatively clear, so the above 2 tests can be cleared.
Let’s check the risk of cataract Part-III
How do you see the light in Fig. 6 (Needs to see actual light)?
If you see multiple lights or you see the light radially like Fig. 7, you may have initial cataract.
In the normal eye, the light going into the eye converge and we can see a thing, but in the case of cataract with cloud in spots, the light going into the eye goes through the cloud and spreads to various directions, seeing multiple or radial lights.
People with this type of cataract see things while driving like Fig. 8.
Food to prevent cataract
Salmon rich in astaxanthin which has strong antioxidant effect is effective.
