Ophthalmology: Do humans have the best eyesight?

Considering the fact that we have a good vision that can see afar of images, colors, and motions. We can also differentiate hundred of colors which uniquely and completely different in shade. I knew that each of us have favourite color that suits to our personalities, types, and preferences. But will it be sufficient to call that we have the best eyesight?

To tell you the truth, I don't have a good eyesight because sometimes I do wear my eyeglasses to make blurry things clear. I know some of you wear eyeglasses as well because I noticed that some of your profile wore eyeglasses. Some of your wear anti radiation eye wears to protect your eyes to radiation coming from various forms of technological devices such as computer, laptop, smartphone, and tablet.

The unexpected rain

We were hit with a strong rain and wind last night. I do not expect to rain that hard because we didn't have any rains these past few days. It was 5 o'clock in the afternoon when I noticed that the sky is becoming grayish and I saw blackish gray at somewhere part of Manila. I reviewed my phone and checked if there is an early sunset, but what I see is not.

It was exactly 5:45 o'clock when it finally rain, drops by drops. Every drop is a big drop that I can hear from our roofs and I saw it outside as well. My father called me to heat and boil some water because he will drink hot coffee. Since it's already 6 o'clock, I decided to wash the rice and cook it. I forgot to tell you that we had no water yesterday because our subdivision is cleaning the tank every quarter. It is also for the safe of everyone because to avoid moss inside the tank. We were advised three days ahead to saved water and prepared from the incoming days. Currently, the water supply is back and my mother is busy washing some of our clothes at the back.

Finding my dog and chicks last night

Suddenly I was hit by a thought about Polar, our dog. She was outside and she is the only dog who don't have its own house. We have three dogs, and the two has its own respective dog house. I went immediately outside to check where she is. Actually, we don't have light in front of our house since we already have enough light coming from street light. I cannot find her due to strong rain and my back is so wet. My umbrella was kept hitting by a strong wind too.

As what I have said earlier, I have poor eyesight most especially at night. Although our eyes can adjust in its environment, but my eyes can adjust just a little. I found my dog inside the tricycle my father owned and it's time to find the chicks which nest in the Alitiris tree (Kerson tree). I cannot use flashlight because it might caught water and will not function anymore. I picked up those chicks and put them besides my rabbit house. They are safe and the rain cannot penetrate inside.

Eyesights comparison (humans vs animals)

There are a big difference in terms of physical and visual pattern of our eyes from animals. Animals have various forms of pupils such as circular, sub-circular, vertical and horizontal. Some eyes have rotate independently, squiggly-shaped pupils. Some eyes have exerting blod and protective eyelids. But if we compare our very own eyesight to animals, who nailed it?

Based on my research, there are several categories which divides the excellency of a certain eye. Are you curious which animal has the best sight? It is the colossal squid. Colossal squids lived at the bottom part of the Antarctic ocean and it is said the they have a soccer ball size of eyes. So big! Which animal sees best in the darkness? It is the Arctic Reindeer. Artic Reindeer is the only animal which eyes respond to the seasonal change. In summer, their eyes are golden, but in winter, it changed to blue and it has 1000 times sensitive to light.

Who sees the most color? (based on spectral sensitivity)

Our eyes are the most unique part of the body. It has the function to view our environment and enjoy its beauty. So how we see the images and its processes? Our eyes are sensitive to light and we have sensory stimuli. The waves of light we see was detected by photoreceptors which converts the light into neuro signals. These neuro signals travel to our brain and process the image.

Based on the spectral sensitivity, surprisingly, dog only have two colors which is blue and yellow. Humans have three and they are blue, green and red. But let me surprise you a little more. Bluebottle butterfly has 15 colors and Mantis Shrimp has 16 colors. Can you imagine if you have a Mantis Shrimp eyes? You can see the world in a whole new level with broad varieties of color.

Meaning, the more types of color photoreceptors we have, the better our color vision is. We cannot say who really has the best eyesight since every creatures made has their own unique and exceptional eye characteristics. There are animals excels in sensitivity, color vision, motion vision and resolution. We, humans placed only moderate compare to those animals, but what's important is how you take care of your eyes. Your eyes are the most beautiful part of your body and that beauty cannot take away from you.
