Creating an environment for eye care
It is important to create a small environment suitable for eye care, providing opportunities to look away and allowing the ciliary muscles to relax.
Facing the television at home is close, in the office is also close to the computer, out of the door building to building or close, such an environment is not conducive to eye health.
Work should pay attention to improve the working environment and adjust the working methods, the office should be kept ventilated and certain humidity, work to pay attention to proper rest, every 1-2 hours of work rest 10-15 minutes (closed eyes or gaze into the distance). When working, pay attention to adjust the height of the monitor, and the keyboard close to the monitor, which can relieve eye fatigue and dry eyes symptoms.
When watching TV at night, it is best to open a light on the back side of the TV set, at about 15 watts-30 watts, the light should be soft, which can play a role in protecting the eyes.
Choosing eye drops is a big learning curve
There are over-the-counter and prescription eye drops. Generally speaking, even health care eye drops should not be ordered often and for a long time because there are some preservatives in them, which are not good for your eyes for a long time. Therefore, when selecting eye drops, you should pay attention to the instructions, whether it is written that contains preservatives.
Therapeutic eye drops have to be used under the guidance of a doctor, with people’s health care awareness, in most residents at home, may be equipped with one or two eye drops for “anti-fatigue” or “anti-inflammatory”. I don’t know, eye diseases are ever-changing, only by the observation of the external eye and can not grasp the root of the disease on the arbitrary use of drugs, often can be a lifelong disaster. For example, “red eye” may be conjunctivitis, but it may also be keratitis, corneal ulcers, subconjunctival hemorrhage, acute iridocyclitis, or acute closed-angle glaucoma.
Some patients with itchy eyes or chronic conjunctivitis buy drugs from pharmacies on their own because their vision is not affected. The damage to vision is irreversible.
I suggest that, under current medical conditions, it is not necessary to have ophthalmic medication in the home, and if eye problems arise, you should seek consultation or treatment from an ophthalmologist in a timely manner, even if you have medication in the home or need to use it for a long time, you should have ophthalmic consultations from time to time.
I remember an 80-year-old man who was prescribed a bottle of tobramycin in the hospital for “eye redness” and got better after 3 days. 3 months later, his eyes were red again, so he used the same medicine and had a stroke 3 days later.
The correct way to order eye drops must also be popularized
I think the correct way to order eye drops is a knowledge that must be popularized, incorrect methods of ordering drops may bring us a lot of problems.
The first drop of eye drops should not be used after opening the eye drops, you can use the first drop of eye drops to rinse out any contaminants that may be present in the bottle. Then use your index finger to pull open your lower eyelid, look upward, and put the drops in the groove of the lower eyelid, never put the drops directly on the black eye. Use your hand to gently pull the upper eyelid after you have finished, so that the drops are evenly applied to the surface of the eye. Finally, remember to put a cotton swab in the inner canthus of the eye and squeeze it for 3-5 minutes.
This is done because the eyes and nasal cavity are connected, and they happen to be connected at the corners of the eyes. If you do not press the corners of the eyes, the drops will soon reach the nasal cavity and throat. Usually one drop of eye drops at a time is enough. When ordering drops often maintain a fixed position for a long time, which can also cause discomfort over time.
Food combination can also prevent eye disease
There is a folk saying that “what you eat is good for you”, although there is no scientific reason, but the eyes are a high energy-consuming and oxygen-consuming organ, so we should ensure a healthy diet with protein, starch, fat, vitamins, trace elements, etc., in the right proportion.
In liver, egg yolk, carrots contain a lot of vitamin A. For people who suffer from eye disease because of vitamin A deficiency, it is certainly helpful to eat some of these foods for the eyes. For elderly patients can eat more fruits, as fruits contain a lot of vitamin C, D, E, which have a role in antioxidant and anti-aging. Goji berries have the effect of nourishing the liver and brightening the eyes, and long-term use is beneficial to eye health. There are laboratories in the United States that have been studying the help of plants such as wolfberry and ginkgo for the eyes.
From a TCM point of view, snake bile has the effect of clearing the liver and brightening the eyes, but this brightening effect needs to be seen from a dialectical point of view, but also with other drugs together to work synergistically, and only when needed to eat.
I do not advocate that people with bad eyes rely on snake bile to achieve the effect of brightening their eyes. The bile should be used in medicine before consumption, as in some areas in the south, it is dangerous to eat fresh bile, as it may be infected with disease.
Stay away from the dangers of tobacco and alcohol
According to research, there are more than 750 chemical components in cigarette smoke, including many toxic substances. Through experiments on animals and clinical patients, this toxic substance can directly affect the metabolic function of eye tissues, resulting in painless, progressive vision loss and color vision impairment in both eyes. Chronic smokers, especially those who drink too much alcohol or are malnourished, will develop tobacco toxic amblyopia.
Smoking can also cause an increase in intraocular pressure, a study showed that in patients with glaucoma, smoking a cigarette that causes an increase in intraocular pressure of more than 5 mmHg up to 37%. Therefore, people with a history of glaucoma or a family history of it should try to avoid smoking.
Alcohol can cause blood vessels to spasm, plus mood excitement promotes increased spasm and higher blood pressure. Patients with diabetes and hypertension are more likely to have blood vessels rupture due to the presence of varying degrees of arteriosclerosis, leading to retinal hemorrhage. If the hemorrhage occurs in the posterior pole, it can cause extreme loss of vision, and if it occurs in the macula, it can lead to blindness. In addition, long-term excessive alcohol consumption, especially frequent heavy drinking of strong alcohol, can cause digestive and absorption impairment, vitamin B deficiency in the body, conjunctivitis, optic neuritis, visual impairment and visual field defects.
Of course, a small amount of alcohol can also be good for the eyes, may have the so-called “blood” function. Studies have confirmed that drinking alcohol can lead to a temporary decrease in intraocular pressure, especially in patients with glaucoma, which is even greater.
Inappropriate diet triggers eye inflammation
We have found that irritating foods, such as spicy foods, can be a trigger for ocular “wheals” and “acute dacryocystitis”. Some seafood may be closely associated with the development and recurrence of uveitis. Therefore, patients with a history of uveitis, especially recurrent uveitis, should be careful to moderate their eating habits.
Between 25 and 40 percent of the elderly suffer from chronic conjunctivitis. After drinking alcohol, the blood vessels in the eyes dilate and become congested, and the bulbar conjunctiva becomes congested, causing dry, uncomfortable eyes. So people with conjunctivitis should be careful to drink less alcohol and eat less spicy foods.
For elderly people, especially those with high risk factors for cardiovascular disease such as diabetes and hypertension, it is recommended to eat more vegetarian food because greasy food, which tends to increase blood viscosity, forms thrombus, which in turn can lead to blockage of the central retinal artery or central vein.
For patients with open-angle glaucoma, especially those who are currently medically diagnosed as having normal intraocular pressure glaucoma, a fat-free diet and vegetarian diet should be the mainstay. A fat-free diet not only lowers IOP but also improves the local blood flow status of the eye. Some studies have shown that tea generally does not cause an increase in IOP, but coffee can cause a transient and mild increase in IOP, while heroin and marijuana can lower IOP.
Since the metabolism of sugar in the body requires large amounts of vitamin B1 and reduces the amount of calcium in the body, vitamin B1 deficiency can exacerbate the degree of myopia, while a decrease in the amount of calcium can weaken the elasticity of the eye wall and contribute to the development of myopia.
Bad emotions also affect eye health
We often see in historical novels or movies that excessive sadness, depression or emotional ups and downs can lead to overnight “blindness”. Now, we know that “overnight blindness” can be “acute central retinal artery blockage” or “acute angle-closure glaucoma” if accompanied by severe headaches. These two diseases are the most serious ophthalmic emergencies, with rapid onset and irreversible blindness within a few hours. The Chinese have a relatively short eye axis, which predisposes them to this disease.
Therefore, it is recommended that people over the age of 40 should have regular eye examinations on the one hand, and on the other hand, if they find themselves with psychological problems, they should promptly adjust their psychological state through various methods. Once the disease has developed, it is important to go to the nearest major hospital. Of course, for the elderly, in addition to regular eye examinations, attention should also be paid to avoid prolonged close eye use and low head work at once.
Proper exercise can slow down eye disease
Exercise can lower blood pressure and prevent coronary heart disease and diabetes, so what effect can exercise have on eye disease? The effect of exercise on visual function has not been reported exactly, but one article reported that three patients with advanced glaucoma showed decreased visual acuity during exercise, and two patients had complete ophthalmologic examination data before and after exercise. two patients had significant decreases in central visual acuity, central concave light sensitivity and visual field, but complete or almost complete recovery after exercise was stopped.
In patients with glaucoma, performing appropriate running exercises can be equivalent to at least one less IOP-lowering drug. However, glaucoma patients should not lift weights and “squatting horse stance”, both of which can raise the IOP and even lead to conjunctival hemorrhage and retinal hemorrhage. In addition, the inversion exercise can lead to an increase in IOP. In particular, patients with advanced glaucoma should limit their activities.
Eye protection when going outside
As environmental pollution increases, the ozone in the atmosphere is destroyed and ultraviolet radiation is enhanced. The onset and development of age-related macular degeneration and cataracts have been shown to be associated with UV exposure. Age-related macular degeneration currently has no ideal treatment and is the number one blinding eye disease in many developed countries.
Although the technology of surgical cataract removal is quite mature, and a better visual acuity can be obtained after surgery, poor adjustment affects the quality of life and faces possible risks of surgery. Therefore, protective glasses should be worn when going out to the south or highland areas. Longer exposure to strong sunlight or watching solar eclipse should also be avoided to avoid solar retinitis.
As people’s standard of living improves, we need good eye protection tools when we go out, such as sunglasses. When winter comes, outdoor skiing and other activities are becoming more common, so you should also pay attention to eye protection to avoid UV damage to the retina from the snow, which can lead to so-called “snow blindness”.
