Well it is really a tough question to answer to. After all there are still so many secrets waiting for researchers to discover. According to some material so far, it is not the same measurement of human eyes as cameras or screens. Resolution of digital appliances is measured in pixels, while human eye is different. In human eyes, there are 5 millions of cone cells, which are sensitive for colors. We can put it in this way that the 5 millions of cones are equal to 5 million of pixels of resolution. But it is far undervalued of our eyes. We know that there are rod cells in our eyes, sensitive for contrast of light and active in dim environment. There are totally 1 million of rods in human eyes, which determined the sharpness and fineness of the picture we saw. We could say that there are maximum 17000 point sources per inch of common person, while, for a good digital camera with a resolution of 2160*1440, there are 400 resolution per inch for a 4*5 printed picture taken by it. The best camera in the world can't be compared with human eyes. If we need to express the pixels of resolution of human eyes, some researchers claimed that it should be 500 million pixels. Recommend you the following article to know more. https://www.madsci.org/posts/archives/may97/864446241.Ph.r.html
Well, for your situation, I have to say that you should not be worried too much. And just calm down. And you should know that water and oil do not mix. And if you use water, it will drive the oil in more deeply and can make the burning sensation worse. And according to some researches, you can put vegetable oil at the edge of a napkin and then touch it to the corner of the eye. And also, you can just pour some vegetable oil in the palm of one hand and use the index finger of the other hand to get the oil into the eye. In that way, it will just make your eyes feel better. Finally, wash your eyes carefully. It will be fine.
It is very possible that you may get photophobia. Photophobia, also known as afraid of light, which is really a bad eye disorder that can lead to further eye problems, such as blurry vision and double vision.

People who suffer photophobia are easy to experience burning, be sensitive to light and hot wind, a feeling of sandy in eyes. The best way to heal it is surgery. And keep eye health is the most important way to prevent photophobia.
Not exactly, but what you should know is that the light is a an important factor to be considered whenever we are using our eyes, no matter reading, watching TV, using computer or even in our habitable room. Dazzling bright light should definitely be avoided. It's too strong a stimulation to the eyes and will soon lead to eye fatigue. On the contrary there may be no enough light be reflected into our eyes in dim light, and we need to try to see figures clearly, which also increases the burden of eyes. Ideally, the light is mild. If you are reading under an energy saving bulb, the surrounding shouldn't be dark also, which is too distinct a contrast. There is a particular kind of eye-protection lamp, especially good for children-using, which is characterized with a high frequency provided by variable frequency electronic ballast, with the power of 30w~40w, frequency of 6000Hz~8000Hz.
There is a large scope of vision outside the central vision, which is called peripheral vision. Put it in this way, perippheral vision means you could see out of the corner of your eyes. Peripheral vision loss creat a sensation that you are looking at everything through a narrow tunnel, which explained exactly why it is called tunnel vision in medical term. Basic causes of peripheral vision loss include retina detachment, glaucoma, eye stroke or occlusion, optic neuritis, papilliedema and concussions. Normally speaking, it won't be triggered by your exercises, unless you did some fierce or contact sports. Eyes are delicate and easy to get hurt. If you got any collision or got any trauma on head, it might cause retina detachment or concussion, which might finally lead to peripheral vision loss. You don't have to be panic about it, because some cases are just temporary, while some are permanent. You just need to visit your ophthalmologist once you found this symptom. With proper and timely treatment, it is possible to prevent it developing to permanent cases. Tunnel vision gives bad direct and guide when you are walking or driving. Be careful. Good luck!
Do you use cosmetics? Your eyelashes keep breaking may due to your mascara dosage. What is worse than it is that you use eyelash curler consistently incorrectly, which also hurt your eyelash. As a result, the lashes become a lot shorter and are all stubby depending on how much you use of mascara and how frequent you use your lash curler! See your product instructions. Well, nothing more than mascara has to be definitely waterproof. There is no doubt that it brittles your lashes, or even cause breakage. I suppose that you can use some promote (re)growth stuff called Talika eyelash gel, or something have the same function products on the market. They may expensive, but at least they are relative.
Yes, it is very possible for people with severe myopia. Because when bungee jumping, people would fall down with accelerated speed of 9.8meters per second.

Meanwhile you should also check your disease history, is there any problem with your heart or brain to make ensure you are OK with this stimulative sports. Anyhow, I dare not to jump it.

You'd better watch this video first and then you will understand the quality of a pair of sunglasses is very important in protecting your eyes when you are playing with bb guns. https://www.youtube.com/watch?hl=en-GB&gl=SG&v=jCjV8-THPdY And the bb gun is very dangerous, don't let the children to play with it. If they use it to shot other people intently for fun, it may cause big problems.
