Can contact lens care solution eliminate COVID 19?

I don't think it can be destroyed because there are many ways to destroy some bacteria, and it takes time, but if you want a care solution, you can't do it.

Treatment solutions are not acceptable.

You can try it first and come back and let us know if it helps.

Normal standard unaided visual acuity (generally referred to as distance visual acuity of 5 meters).

For (that's what it said.)

In other words, when this vision is reached, it is considered normal vision.

Judging from our current international standard eye chart, the best unaided eye vision is what was originally said.

These unaided visual acuity are tested in one eye at 5 meters.

The decimal method is, and the 5-point method is.

In general, normal naked visual acuity can be achieved, that is; People with refractive errors (nearsightedness, farsightedness, astigmatism) may have lower than normal visual acuity, but they can be corrected to normal vision by wearing glasses.

The best eye vision is 1, if you want to measure your eyesight, it is best to go to a regular hospital or a regular optical store to measure your vision, if you are nearsighted, you can wear glasses, you must pay more attention to the protection of your eyes, try not to look at your mobile phone or computer all the time, if you are tired, you can do eye exercises, which has a relieving effect, and you can also look at the distance to relieve it.

Normal vision is normal on the left and right, and you can use an eye chart to test the power of your eyes. Be careful not to fatigue your eyes, watch TV for a long time, and use a computer. After using your eyes for a while, you can get up and look at the sky, or close your eyes and rest for a while, if you feel that your eyes are tired, you can do eye exercises, and maintain a good posture of reading and writing.

If the unaided visual acuity is above and above, it is considered normal vision. The best eyesight at the moment is:

To maintain good eyesight, you need to develop good eye habits

1. The maximum time to use the computer is not more than 2 hours, and when it must be used continuously, take a break for half an hour for every 2 hours of use.

2. When resting (including usual), first do eye exercises, close your eyes for 10 minutes, and then, gently rub your face and rub your eyes, and then look far away (whether day or night, the purpose is to relax your eyes).

3. To surf the Internet at night, there should be an incandescent lamp with 15 watts in front of the computer. Internet access during the day, and the light in front of the computer should not be too strong. (It is better not to use energy-saving lamps).

4. Pay attention to posture and light when reading and writing.

5. Maintain a certain amount of outdoor activities every day, see more green plants, and look into the distance;

6. Eat less sweets and more purple foods.

Children under the age of 18 who have normal vision now should be prevented from developing myopia. It is recommended to take two sachets of Joy Vision Nutrients every day, and you can see the change in 7 days. If you take it for a period of time, you can prevent myopia.

Most people's eyesight is good eyesight, but my eyesight is much better, and I can see clearly at twice the distance, which should be the best eyesight.

Let's understand what is myopia?

Myopia is also called short-sightedness because it can only see far and not close. When the eye is at rest, the parallel light from infinity passes through the refractive system of the eye and then converges to form a focal point in front of the retina of the light-sensitive layer of the eye, and forms an unclear image on the retina.

The development of the eye, in fact, begins with farsightedness and experiences hyperopia |Stop|If you can't stop the car, you will become myopia if you continue to overdevelop.

If farsightedness is in the normal range, glasses are not required.

Infancy: 0-3 years old, is the most critical period of visual development, and it is also the period of the fastest change in refractive power in a lifetime. Degree of farsightedness: 600 300 degrees.

Preschool age: 3-7 years old, is a sensitive period for visual development and the beginning of the establishment of a refractive profile. Degree of farsightedness: 250-150 degrees.

School age: 7-12 years old, which is the period when myopia is prone to high incidence and is also the best period for myopia intervention.

Farsightedness Orthopedia: 175-0 degrees.

For example, a 6-year-old child should have about 200 degrees of farsightedness, and if it is only 75 degrees when checked, then it may quickly become myopia.

Hello, it should be, the key is to pay attention to eye hygiene. Pay attention to timely adjustment to avoid eye strain.

The standard is a five-meter count! The highest visual acuity decimal count is.

Hello, the best vision for a normal adult is. Vision has a great impact on our normal lives. It is recommended that you should pay attention to protect your eyes to prevent the phenomenon of vision loss.

It is advisable to eat more vitamin-rich vegetables and fruits, such as blueberries, grapes, apples and other fruits.

It is recommended that patients should pay attention to eye care, do not stay up late, rest on time, and eat reasonably.

There is a tribe in Africa, the Maasai (transliteration). The Maasai live in the African savannah. They live in tents, surrounded by endless grasslands except for dead grass and bushes.

The Maasai people who lived in this primitive environment developed superhuman visual abilities. They can see objects from several kilometers away, as well as objects that move instantaneously and clearly see objects tens of meters away in the dark.

When a Japanese television station interviewed the Maasai people, they tested the eyesight of the Maasai people, and the two people with the best eyesight in the tribe had more than one eyesight.

The eyesight of each age is different, people's eyesight is slowly developed, about 8 years old or older can be reached, everyone's eyesight is different, and the above are normal.

1. Central vision: that is, the visual acuity determined by people usually looking at the eye chart, including distance vision and near vision. Patients with hyperopia present with better distance vision than near vision; The opposite is true for patients with myopia.

People with astigmatism have poor distance and near vision. When the near and distance visual acuity is above or above, the central visual acuity is normal.

2. Peripheral vision: When the eyes are fixed on a certain target, the range that can be seen in the non-fixation area is large or small, which is called peripheral vision, which is often referred to as "residual vision". The range of peripheral vision in a normal person is quite large, up to 90 degrees on both sides, 60 degrees above and 75 degrees below.

Patients with myopia and night blindness have poor peripheral vision, and some fundus diseases can also cause peripheral vision loss.

3. Stereopsis: Stereopsis is a kind of superlative vision, that is, on the basis of normal vision in the center of the two eyes, through the harmony of the two hemispheres of the brain, you can feel the distance relationship between objects in space. Some people have normal central vision but abnormal stereopsis, which is medically called stereopopia.

To prevent myopia, we must learn to use our eyes scientifically, read and write in a correct posture, keep the distance between our eyes and books about one square foot, and read books continuously for no more than one hour, and look at the distance or look at green plants every once in a while. Do more eye exercises during breaks, eat more carrots, apples, bananas, cuttlefish, eggs and other foods, and take a walk or exercise outdoors in your spare time.

It is recommended to take Joy Vision Nutrients, myopia can recover quickly, and the younger the better. You only need to take one sachet twice a day, with warm water, and stick to it for a period of time.

China generally uses the decimal record method and the quintal record method (the international standard eye chart uses the decimal record method, and the standard logarithmic eye chart uses the five-point record method). The eye chart has a total of 14 rows, and the letter E gets smaller and smaller from top to bottom, and the corresponding visual acuity is from top to bottom.

The widely used vertical eye chart, there are only 2 large optoscopes at the top, 3 optograms in a row, 8 optoscopes in a row below, 2 in a row, and seeing a visual target represents an improvement in vision, while 8 a row of optographic targets is.

There are 2 ways to represent visual acuity, namely the standard logarithmic eye chart and the decimal record eye chart.

2 standard logarithmic eye charts Decimal records eye charts ---

Generally, according to the measured visual acuity, the eye chart will have a corresponding visual acuity, either the representation of the new eye chart or the representation of the old eye chart.

The new eye chart and above are normal vision, and below it may cause myopia, farsightedness, astigmatism, etc.

The old eye chart and above are normal vision, and below it, there may be myopia, farsightedness, astigmatism, etc.

The power of the eye will be different depending on the value, and the specific result of refraction will be used to see the visual acuity.

Nowadays, there are more and more children with myopia, and they are getting younger and younger, and regular eye checks can prevent the occurrence of myopia, which is also good for children's future education and employment.
