During this period of time, the Spring Festival became a key word, but for the Department of Optometry of the Ophthalmology Center of Zhejiang Medical University, they also entered the “Spring Festival†state this week.
Director Ni Hailong of the Department of Optometry said: “The outpatient service volume is twice as usual, and the daily outpatient service volume is nearly 2000-2500 person-times. The doctors are all on duty.â€
Money reporter survey found that the ophthalmology is not a special case of Zhejiang Spring Festival, from this week onwards, major hospitals in Hangzhou City, eye clinics have appeared overcrowded scenes.
Ni Hailong said that nearly half of the patients who see a doctor recently are young children. Obviously, this is related to the coming winter vacation. The focus of attention of parents is still eye health, vision, myopia, and light damage.
Children's vision problems make parents very anxious. However, how many misconceptions about children's eyes?
Ni Hailong suggested that as far as possible make an appointment before taking the child to the hospital. Children and adolescents often need dilated pupils, cycloplegic refraction and reexamination. This means that it usually takes 1 day to get it down, so retesting can be a different time. It's best to go earlier and it will be easier and faster. During the winter vacation, it is necessary to pay attention to children's eye health, especially to strictly control the use of electronic products.
Myth: Glasses can be worn without wearing
Timely scientific wearing glasses can control myopia
Ms. Zhu's daughter is 12 years old. In fact, as early as the age of 9, the child checked out myopia. The doctor also repeatedly advised her to give glasses to the children, but Ms. Zhu refused again and again because she had such an experience in her memory: the glasses could not be worn if they were worn, and they could not wear if they did not wear them.
Ni Hailong frankly said: "Worried that children can not get off once wearing glasses. So they seek massage, acupuncture, therapeutic apparatus, eye exercises, etc. In fact, these children can not reverse or control the development of myopia." Myopia occurred in the development of genetic Factors and a large number of acquired environmental factors, so children and young people will still show a deepening trend after wearing glasses, not wearing glasses wrong.
His advice is that timely and scientific optometrics will enable children to obtain clear and comfortable visual quality, which will help to slow down the development of myopia compared to the visual state of being in a fuzzy fatigue without wearing glasses. "After wearing glasses, we should pay more attention to good eye habits, encourage as many outdoor activities as possible every day, try to avoid prolonged use of eyes for a long time, and avoid excessive use of televisions, game consoles, computers, and mobile phones."
In addition, as many outdoor activities as possible each day, outdoor activities under natural light, telephoto, the pupil is relatively reduced, so that the eyes are in a state of relatively easy and comfortable to see, is also recognized as a way to prevent myopia. "If you read 15 minutes at a short distance, you can walk up and walk for 15 seconds. You can use activities such as playing table tennis. It is a useful activity to look at the eyes."
Myth: Less than 1.0, vision is not normal
The standard of normal vision varies from age to age
I wish my father’s son had just entered the first grade. During this semester, his physical examination revealed that his son’s left vision was less than 1.0. This was not a holiday. Mr. Zhu rushed to the hospital with his children.
Ni Hailong explained that this is an overly sensible misconception. A child’s visual acuity of 1.0 does not mean that there must be a problem with his eyesight. "To know that the standard of visual acuity is different in different stages of infant development, the eye's refractive state also gradually transitions from hyperopia to normal vision and may continue to develop into myopia."
It is understood that the normal visual acuity of children within 1 year old is usually about 0.2, and the main activity range is mid-distance. The diameter of dilated cycloplegic refraction is mostly about 300 degrees hyperopia. This hyperopia is physiological—no correction is needed. By the age of 2 to 3 years, the range of activities was expanded and there was more attention activity. At this time, the visual acuity was about 0.3-0.5, and the dilated cycloplegic refraction was 200-250 degrees hyperopia. At the age of 4-6 years, the visual function was basically completed. The visual acuity was about 0.6-0.8, and some of them reached 1.0. The mydriasis cycloplegic refraction was mostly about 150 degrees hyperopia. At 7-8 years of age, the visual acuity is usually 1.0 or more, and the dilated cycloplegic refraction is mostly about 50 to 100 degrees hyperopia.
Regular vision and refractive status examinations in early childhood can help predict the analysis of future trends in refraction or myopia, and provide better and timely interventions.
Myth: Children's eyes are quite cute
Amblyopia strabismus is difficult to cure when it is missed in primary school
The younger brothers occasionally flitted their eyes and the family was very happy. When he was in elementary school, Mr. Ma discovered that the daughter was not a joke and needed treatment.
Ni Hailong reminded that amblyopia and strabismus have passed the elementary school and have missed the best sensitive period of treatment. "Light and formative stimuli are important factors in children's visual development. Ages 2 to 6 are important for correcting vision. Amblyopia and strabismus require early detection and early treatment."
He suggested that parents should pay attention to children's eye abnormalities and promptly discover timely medical treatment.
These problems can be diagnosed by refractive correction or partial strabismus surgery. Frequent periodic reviews and adjustments to corrective training regimens can enable most children to regain their eyes in critical periods of visual development between the ages of two and three and six. Balanced light and form stimuli restore and consolidate binocular vision functions such as binocular fusion and stereoscopic vision.
However, if these problems are discovered after primary school, a sensitive period of missed treatment is required. Second, after entering primary school, it is difficult to have time to cooperate with strict and frequent periodic review and adjustment of correction training program, resulting in poor treatment and less effective. Especially after 12 years of age, it is extremely difficult.
Winter special eye reminds
Less watch TV less use Pad
The winter vacation arrived, watching the small eyes that were cured, Ni Hailong worried again.
Studies have found that blue-violet light near the ultraviolet side damages retinal cells, and many electronic products in the display contain blue light. "More importantly, close reading is an important factor in the development of myopia, but also more likely to lead to dry eye, fatigue. Therefore, to reduce reading at close range, to minimize the time to contact various types of video."
For some workers in IT and other industries, if they have to contact various videos for a long time, Ni Hailong's suggestion is that they can choose to wear special film layers to design optical glasses (that is, try to keep the visible light transmittance and retain the benefits of blue light. Blue-green light, while filtering out harmful blue-violet light, protects eyes from excessive blue light interference.
