The eye is the bare organ because the eyes have to see images taking in light unlike other organs such as the lungs or the heart.
What happens if the bare eye is exposed to UV rays during summer? The risk to have cataract becomes higher. There is the data that people who live in an area which latitude is low where are stronger UV rays have more cataract. That is why care is important. In fact, it is said that cataract is a disease that most people experience such as 50% of 50’s, 70% of 60’s and more than 90% of 70’s or above. The lens of the eye absorbs 99.9% of UV rays but this causes cataract. Why do UV rays make the clear lens of the eye white and cloudy? The lens of the eye is something like the white of an egg. The white of an egg is clear when it is raw, but it becomes white when it is heated. Light energy of UV rays is accumulated damaging the lens of the eye, resulting in becoming white and cloudy. The key word for the aftercare of the eyes is Lutein. It can be expected that taking lutein decreases the damage of UV rays during summer, reducing the risk of cataract. Lutein is rich in spinach. The amount of Lutein per 100 g: Broccoli: 1.4 mg Greenpeace: 2.4 mg Spinach: 12.2 mg The efficient cooking method to take lutein is a dish which oil is used. Lutein is soluble in oil so lutein is easier to be absorbed when it is cooked with oil such as spinach and corn sautéed in butter (Fig. 1).
