Update Date: 2024-05-22 Source: Network

Some people's vision may decline due to a lack of attention to eye hygiene, which can affect their normal life. Some people may experience a significant difference in vision between their left and right eyes, in which case it is important to develop good eye habits. Eating foods that are beneficial for eye health, such as broccoli, goji berries, carrots, and blueberries, can help improve vision. What is the normal vision for both eyes? What should I do if there is a large difference? Let's take a look.

1. What is the normal vision for both eyes?

The vision of both eyes is consistent, and the standard vision for adults is 1.0. However, the physiological characteristics of the eye are that it transitions from being farsighted to nearsighted from birth to age 6, so children under age 6 are unable to achieve standard vision. At age 3, vision is approximately 0.6; at age 4, it is around 0.8; and at age 6, it is basically close to or reaches the standard vision of adults. If a child's vision is lower than the standard, they can undergo optometry or fundus examination at an ophthalmology clinic. Elderly people generally have vision lower than 1.0 due to vitreous opacity, lens opacity, or poor ocular muscle regulation.

2. What should I do if there is a large difference in vision between both eyes?

The vision of both eyes should not only be normal but also balanced. If there is a significant difference in vision between the two eyes, it is necessary to undergo cycloplegic refraction. If there is an organic disease in the eye, it may cause poor vision in the affected eye. In this case, the doctor will perform an examination to observe which part of the eye has a problem and whether it can be treated or surgically corrected. If treatment is possible, vision may improve after surgery, but whether it can return to its previous state before surgery or illness varies from person to person. If there is a significant difference in vision between a child's two eyes, it is necessary to undergo cycloplegic refraction to check for amblyopia caused by refractive anisometropia.

3. Methods to improve vision

1. Correct eye use. In daily life, correct eye use is the key to maintaining good vision. It is recommended that people maintain an appropriate distance from related items when reading, writing, or working. At the same time, avoid prolonged eye strain and take breaks to relax the eyes after a certain period of time to effectively improve vision.

2. Reduce the use of electronic products. Nowadays, electronic products are widespread, and many people rely heavily on them. However, prolonged use of electronic products can cause serious harm to vision. Therefore, it is recommended that people reduce the use of electronic products in their daily lives.

3. Look into the distance. In daily life, it is recommended that people try to look into the distance when resting their eyes. It is advisable to look at green plants more often, which can help improve vision to a certain extent.
