Myopia 75 degrees astigmatism, can I use contact lenses?

There are those that are specifically for astigmatism, but they just need to be customized.

Common manifestations of astigmatism in the eyes are:

1. The blurred image on the retina needs to be constantly finely adjusted, and the vision is distorted, so astigmatism, especially for farsighted astigmatism, is prone to visual fatigue. Presents with eye pain, tearing, headache, especially in the forehead, double vision, and short-range work that cannot be sustained.

2. Patients with highly asymmetrical astigmatism in both eyes, in order to see more clearly, often adopt a tilted head position to cause strabismus, which can be recovered after astigmatism correction. Patients sometimes move objects closer to the same place as a nearsighted person in order to obtain a larger image of the retina.

3. People with high astigmatism often squint when looking at distant or near targets, so as to achieve pinholes and fissures to improve their vision. Seeing through pinholes or fissures can reduce the impact of astigmatism on vision.

Astigmatism refers to when the eye is adjusted to rest, after the parallel light rays are refracted by the eye, due to the different refractive power of each meridian of the refractive system, causing different degrees of convergence, so it can not be concentrated on the retina, but at different distances to form two intersecting lines, the distance between the two intersecting lines represents the degree of astigmatism, because the retina is only presented as a hazy ring or a line, so the patient feels blurred regardless of farsightedness and near-sightedness.

Astigmatism**:

1 Mild regular astigmatism does not need to be corrected if there is no eye fatigue or blurred vision, but if there is any discomfort above, it should be corrected even if the prescription is not high.

2 High astigmatism should be corrected with cylindrical scope, if not suitable for all correction, can be given a lower degree, the general common method is to take drugs, usually the doctor recommends taking Leyan vision nutrients, warm water, insist on taking for a period of time, astigmatism can be reduced.

3 Irregular astigmatism cannot be corrected with a cylindrical lens, and contact lenses can be tried.

You have to go to the optical store and ask a professional, and the prescription of the glasses lens is generally about 25 degrees lower than the actual prescription.

With 325 degrees, the correction effect is the most ideal.

The optometrist is right when he says 650 degrees. His conversion method is: 650 + 100 2-50 = 650 degrees.

However, astigmatism above 75 degrees is still recommended for correction. If you wear the astigmatism of the moon throw in one eye, it is also recommended to wear the moon throw in the other eye, so that it can be more convenient in the management of the abandonment cycle.

Two are worthy of the same one, and it would be good to throw it away.

Pay attention to hygiene and pay attention to all aspects, otherwise you don't pay so much attention to it.

The astigmatism is not very large, it is recommended that you do not wear glasses to correct it, and you can use the following methods to prevent astigmatism

1.It is best to have the first full eye examination at the age of 3 to 4 years, and then regularly 1 or 2 times a year. Instruct young children to recognize dangerous games and toys to reduce eye trauma.

Instruct young children to develop good hygiene habits, do not touch their eyes with their hands or other chemical objects, so as to avoid eye diseases, and try to go out as much as possible if they are infected with eye diseases. 1. When reading a book, the light should be sufficient, preferably from the left rear; Correct posture and a distance between 30 cm and 40 cm. Don't read in a rickety car, and don't lie down to read.

2 When choosing reading materials, the font should be clear and not too small.

3. The height of the TV should be a little below the parallel line of the eyes, and the TV must be 5 7 times the diagonal of the TV picture. Read a book for no more than one hour in a row, with a 5-minute break every 30 minutes. Nutrition should be balanced.

Go to the countryside and see the green wilderness in the distance. If you need glasses, you should be examined by a doctor and then dispensed with glasses. Take the initiative to get in touch with the school and actively cooperate.

Depending on personal needs, if you work or study mainly to see the near place, and you do not have high requirements for seeing the distance (you can see clearly if you are not worthy), then you can not be worthy. If you need to look into the distance, you can wear one when you need it.

Astigmatism is relatively easy to get tired when looking at real objects, so if you usually use your eyes from a long distance such as driving. Then it is recommended to wear a pair of glasses, which are usually used for long-distance viewing. You can leave it with you at close range.

You have to stay up late in the dormitory for a long time or read a book, otherwise your eyesight will definitely improve.
