Human eyes have over two million working parts.
Eyes.jpg

Per the Canadian Association of Optometrists, your eyes have two million working (or moving) parts. On top of that, they also have seven million cones, which are what allow you to see both color and detail. As for your ability to see in the dark, that's made possible with the help of a whopping 100 million cells, or rods.

The only organ that doesn't need a blood supply



Well, not an organ, but just one part of it.

The cornea is the outermost membrane of the eye. And, of course, it doesn't need blood vessels, because it has to remain transparent.

How else would we see the world through it?

But any tissue needs blood supply to get oxygen.
No, it doesn't - the cornea "gets" oxygen from the surrounding air.

WHY do you see colored circles while rubbing your eyes?

Color-circle.jpg


You may have noticed that every time you rub your eyes, the colored flashes are always of a different shape and color😏

Pressing on the eyeball causes mechanical irritation to the retina and optic nerve.

This signal goes to the visual centers of the brain, which perceive it as a normal signal from the retinal receptors.

👁� Cataract

Cataracts.jpg

is a condition occurring in the lens of the eye when proteins break down — usually due to age, physical trauma, or illness — and clump together. As these clumps grow and change, vision will become blurry; you may get double vision in one eye; your vision may turn yellow or become darker; or you may experience haziness like you are in fog. These protein clumps prevent light from passing through the eye as normal, so the images transmitted to the brain from the retina and optic nerve will be incomplete.

Treatment :- compound called 5-cholesten-3b,25-diol sterol improve lens transparency. The chemical binds to misfolded proteins in the eyes of mice, partially reversing cataracts.

@Health Cataract surgery is an outpatient procedure that does not take very long. Although healing can take several weeks and getting restored vision can take several months, the procedure itself is low-impact. Your eye surgeon will make a small incision in your cornea, and then another small incision in the capsule containing the lens of your eye. Finally, they will break up the lens with a probe, either using lasers to soften the lens first or just using sound waves to break the lens up. The probe will remove the pieces of lens, and then your surgeon will replace the lens with an intraocular lens (IOL), an artificial lens made either of silicone or plastic. This lens will take the place of your damaged biological lens.

Why our eyes are red from lack of sleep?


Eyes need a certain amount of time to regain their natural moisture level after a day's work.

They rest at night, but if those precious hours of sleep are stolen from them, they will retaliate with redness.

In winter, the redness is more pronounced, because at this time, the moisture outside freezes, and indoors, it is dried by the heating.

How Does the Eye Move?
 

There are six extraocular muscles responsible for the eye's rotational movements.

The eye muscles are divided into three groups: the muscles inside the eyeball, the eyelid muscles and the extraocular muscles, which ensure the rotation of the eyeball inside the eye socket.

Facts:-
✅Our lungs inhale over two million liters of air every day, without even thinking.

✅When humans lose weight, about 80% of the fat is converted into carbon dioxide and exhaled through the lungs.

Do you see numerous little dots in the kidney?
 

These are all nephrons as its functional units. They are the ones responsible for the entire urine formation. The nephron is a complex system of "tubes" through which urine passes and gets filtered.
