High pressure in the eye, also known as ocular hypertension, can occur when fluid builds up in the eye because it's not draining at its normal rate. This can be similar to a water balloon, where the more water that's added, the higher the pressure. If the pressure gets too high, it can damage the optic nerve in the eye, which can lead to gradual vision loss over time. Ocular hypertension can also be an early sign of glaucoma, an eye disease that can cause irreversible vision loss if left untreated
Here are some things that happen when you blink: Distributes tears Blinking spreads a fresh layer of tears across your eyes, which prevents them from drying out. Removes debris Blinking removes dead cells, dried tears, and other debris from your eyes. Sends nutrients Blinking brings nutrients and other substances to the surface structures of your eyes, keeping them healthy. Expels excess moisture If there's too much moisture, excess tears are expelled through the tear ducts and into your nasal passages, which can cause a runny nose when you cry.

Research has suggested that people who apply eyeliner run the risk of contaminating their eye and causing vision issues. When eyeliner is applied on the inner eyelid, it is likely to migrate into your eye, potentially causing damage. Eyeliner ingredients commonly include wax, oils, silicones, and natural gums. These ingredients are designed to make your eyeliner stay on, so they are difficult for the eye’s natural cleaning process to remove once they are introduced into the eye. When makeup enters the tear film, it can cause:
Drinking too much water in a short period of time can increase intraocular pressure (IOP) in the eye. A study found that IOP increased significantly 15 minutes after drinking water and remained elevated for 45 minutes. Drinking a quart of water in less than five minutes has been shown to be dangerous. Instead, it's recommended to drink small amounts of water frequently to stay hydrated.
, blinking is important for eye health. Blinking helps keep eyes lubricated and comfortable, and protects them from irritants and debris. Blinking also helps prevent infection, clears and brightens vision, and replenishes the tear layer for contact lens wearers
