What is the difference between dry eye syndrome, floaters, and presbyopia? Which nutrients are the most antioxidant and good for the eyes?
What causes dry eye syndrome? May dry eyes for a long time cause corneal disease?
The main causes of dry eye syndrome are insufficient tear secretion in the aqueous layer, insufficient secretion in the oily layer, insufficient secretion in the mucus layer, and excessive tear evaporation. Generally speaking, tears will provide nutrients to the cornea. When the secretion of tears is not enough, it will cause damage to the corneal epidermal cells, resulting in corneal rupture or foreign body sensation.
Patients with dry eye syndrome may easily feel sore eyes, get tired easily, feel sleepy, itchy, have a strong foreign body sensation, are prone to secretions, are sensitive to external stimuli, and prone to blurred vision, etc. This may be the early stage of dry eye syndrome. Further deterioration may lead to eye redness, congestion, keratinization, corneal rupture, etc. Over a long period of time, it may cause corneal lesions and affect vision.
Blinking too few times may also be related to dry eye syndrome. The average number of blinks for a normal person is 12-15 times per minute, and the interval between each blink is about 2.8-4 seconds. If you have been staring at the screen to catch up on dramas or need to stare at the screen Office workers, as well as the elderly whose tear gland secretion has deteriorated due to age, and oil duct obstruction caused by eyelid inflammation, all have a higher chance of developing dry eye syndrome.
How to check for dry eye syndrome? What nutrients help prevent dry eye syndrome?
When dry eye problems are suspected, the clinic will use instruments to analyze the patient’s canthus lipid layer, and then check the meibomian gland function based on the thickness of the lipid layer. The normal tear film break-up time falls between 10 and 30 seconds. If the tear film break-up time is less than 10 seconds, it indicates dry eyes.
To prevent dry eye problems, you can moderately supplement vitamins A, C, E, DHA and fish oil. The two most important nutrients of omega-3 in fish oil are DHA and EPA. The content of DHA is particularly high in the retina and brain. It is an important component of brain cells and visual cells and participates in the transmission of light signals by retinal cells. It plays an important role in visual function.
As for the main role of EPA is to improve triglycerides, it has the effect of cleaning blood vessels, reducing inflammation and improving cardiovascular disease. It is recommended that those in need can supplement some anthocyanins, fish oil, bilberry and linseed oil. Do daily health care for dry eye syndrome.
Are floaters related to high myopia? 3 dietary supplements to help with antioxidants
There is a “vitreous body” in the eye structure that maintains the shape of the eye. It is composed of collagen fibers and hyaluronic acid. It will slowly degrade with age. In addition, blue light and ultraviolet rays in the environment will cause the fibers to become disordered. The most important thing is The reason is that hyaluronic acid liquefies, and after liquefaction, it will form small water droplets. When light is projected in, it will create shapes of different sizes, ranging from small dots, circles, lines to spider webs, resulting in a visual sense of shaking debris. , sometimes you can even see images such as “flash” or “lightning”.
Floaters often occur in patients who have undergone cataract surgery and people after laser surgery. Generally speaking, floaters are physiological, degenerative, and pathological, and must be differentially diagnosed by an ophthalmologist. They are common. Suitable for people who are over 50 years old, highly myopic, have eye trauma or complications from cataract surgery, diabetic retinopathy, etc.
Floaters themselves are not terrible, but if they worsen to the point where flashes of light, lightning, etc. occur, you must seek medical attention to see if there are any combined holes in the fundus, which can lead to retinal detachment in severe cases. If it is mild floaters, you only need to follow up regularly at the clinic. You can supplement more vitamin A, anthocyanins, fish oil omega3, etc. on weekdays. Flavonoid compounds such as anthocyanins have strong free radical scavenging properties. For antioxidants, you can also eat yellow-orange foods including egg yolks, corn, carrots, etc., which are helpful for your eyes.
Does presbyopia cause the crystalline lens to become less elastic? Should cataracts be treated simultaneously?
Presbyopia is the loss of elasticity of the lens that adjusts the focal length, and the weakening of the muscle adjustment ability of the ciliary muscle, which affects the eye’s ability to focus on close-up scenes, causing changes in our vision at close range, which makes it difficult for reading or reading small fonts. It is particularly difficult and is called presbyopia.
Presbyopia usually reaches more than 100 degrees at the age of 40, and gradually increases by about 10 degrees every year. The only way to treat presbyopia is to wear reading glasses or presbyopia laser. If there is cataract, you can consider replacing the artificial lens. Implanting a multifocal intraocular lens simultaneously treats cataracts and presbyopia, and can even improve myopia, farsightedness, and astigmatism.
Is ultraviolet rays the culprit of lens lesions and cataracts? 6 Nutrients to Increase Antioxidant Power
In fact, the most lethal factor in the environment for the eyes is ultraviolet rays. As the weather changes, summer sun exposure continues to increase compared with the past two decades. Ultraviolet rays are divided into UVA, UVB, and UVC according to wavelength. The shorter the wavelength, the stronger the energy. When ultraviolet rays penetrate the atmosphere and enter our lives, blocking ultraviolet rays from harm has become a must-have health awareness for modern people.
Although UVC is effectively blocked by the ozone layer, if UVB directly reaches the eyes under the scorching sun, it may cause cataracts and retinopathy. For example, when you go to the beach for a short time or engage in welding work, high-energy UVB for a short period of time may cause the nuclear protein of the conjunctival epidermal cells of the eye to absorb energy, causing temporary strong photokeratitis, causing the patient to shed tears, be photophobic, have red and swollen eyes, and become incapacitated. Open. As for excessive ultraviolet rays passing through the eyeball for a long time, it will cause the content of incompatible fibrin in the lens to increase, affect the patient’s vision, lead to lens lesions, and eventually develop into cataracts.
Therefore, be sure to wear a hat and sunglasses when going out to block UV rays. The hat has a physical sun protection function and can also block UVA from causing sunburn to the skin, as well as the possibility of sunburn on the scalp due to reduced hair. It is recommended that the daily diet should be based on a balanced diet of fruits and vegetables, and ensure adequate intake of lutein and zeaxanthin. For health food supplements, you can choose antioxidant-rich lutein, SOD, astaxanthin, Q10, vitamin A and fish oil.
In addition, some drugs will enhance the damage of ultraviolet rays to the body, such as sulfonamides, tetracyclines, diuretics, tranquilizers and oral contraceptives. People who are taking the above drugs should pay special attention. As for UV sterilizers available at home or at work, be careful not to look directly at the sun or UV lamps when using them. The following is a brief summary of different eye problems and dietary supplement recommendations:
Cataracts are mainly lesions of the lens. If supplemented, astaxanthin and anthocyanins should be used.
For macular degeneration in the center of the retina, the supplement association recommends taking lutein, astaxanthin and DHA for maintenance.
If the cornea is short of oil or water, resulting in dry eye, you need to supplement more anthocyanins and omega-3.
For floaters caused by vitreous lesions, suitable supplements are vitamin A, anthocyanins, and fish oil omega-3.
Presbyopia caused by abnormal ciliary muscle regulation can be supplemented with more astaxanthin and anthocyanins.
In addition, there are more than 2 million people with diabetes in Taiwan. Diabetic people have long-term elevated blood sugar, and their crystals are prone to degeneration under the influence of excessive sugar. In addition, high blood sugar slows down wound healing and causes more complications for patients, increasing the risk of surgery. Diabetic patients are at risk of retinopathy. Therefore, if you have blood sugar control problems and high myopia, it is best to undergo annual eye tracking to ensure eye health.
