What does 20/20 vision mean?

Normal vision is called 20/20 vision. The numbers 20 and 25 mean that someone with this visual acuity must stand five feet closer to an object than someone with 20/20 vision does to see it clearly. People with 20/25 vision can strengthen their sight by wearing eyeglasses or contact lenses or by undergoing LASIK surgery.

What happens if you have 20 25 vision?

People with 20 25 vision might experience eye strain or fatigue quicker than those with perfect vision, especially during prolonged periods of screen use. Computers, smartphones, and tablets require the eyes to focus and refocus constantly, which can be tiring if your vision is not optimal.

What is 20/20 notation?

The 20/20 notation is testing visual acuity, which means the sharpness or clarity of your vision. It measures your ability to discriminate fine details at a standardized distance. The top number refers to the testing distance, typically 20 feet.

Risk warning: Digital asset trading is an emerging industry with bright prospects, but it also comes with huge risks as it is a new market. The risk is especially high in leveraged trading since leverage magnifies profits and amplifies risks at the same time. Please make sure you have a thorough understanding of the industry, the leveraged trading models, and the rules of trading before opening a position. Additionally, we strongly recommend that you identify your risk tolerance and only accept the risks you are willing to take. All trading involves risks, so you must be cautious when entering the market.
