Eye vitamins during cataract

Eye vitamins in cataracts: understanding, science and effective strategies

Chapter 1: Cataract – extensive review

Cataract, clouding of the lens of the eye, is one of the leading reasons for the deterioration of vision and blindness around the world. Understanding the mechanisms of its development, risk factors and potential strategies for slowing progression is crucial for maintaining the health of the eyes throughout life. The lens, usually transparent and elastic, focuses the light on the retina, allowing us to see clearly. With age or under the influence of certain factors, the lens can lose its transparency, which leads to blur, worsening vision at night, sensitivity to light and, ultimately, to a significant decrease in the quality of vision.

1.1. Cataract types:

Cataract is classified by the location and reasons for its occurrence. The main types include:

• Age cataracts: The most common type associated with the natural aging of the body. Proteins in the lens begin to collapse and stick together, leading to clouding.

• Congenital cataracts: Present at birth or develops during the first few years of life. It can be caused by genetic factors, infections during pregnancy (for example, rubella), or metabolic disorders.

• Traumatic cataracts: It occurs after the eye injury, such as a blow, a puncture or the effect of chemicals.

• Secondary cataract: It develops as a complication of other diseases such as diabetes, or after taking some drugs, in particular corticosteroids. Sometimes it can occur after operations in the eyes for other reasons.

• A backcapsular cataract: It is located on the back of the lens. Often progresses faster than other types and can cause significant impairment of vision, especially in bright light.

• Nuclear cataracts: It develops in the center of the lens (nucleus). Over time, the core can turn yellow or even darken, which affects color vision.

• Cortical cataracts: It begins with the periphery of the lens (bark) and gradually spreads to the center. It manifests itself as wedge -shaped cloudings that can cause glare and vision of vision near.

1.2. Risk factors for cataract development:

Many factors can increase the risk of cataracts. Awareness of these factors allows you to take preventive measures and slow down the progression of the disease.

• Age: The most significant risk factor. The risk of cataract development increases significantly with age, especially after 60 years.

• The effect of ultraviolet (UV) radiation: Long -term exposure to sunlight without eye protection can accelerate the development of cataracts.

• Smoking: Smoking increases the risk of cataracts due to increased oxidative stress in the body.

• Diabetes sugar: Diabetes increases the risk of cataracts and can accelerate its progression. A high blood sugar may damage the proteins of the lens.

• High blood pressure: Hypertension can have a negative effect on the health of the eyes, including an increase in the risk of cataract development.

• Obesity: Obesity is associated with an increased risk of developing various diseases, including cataracts.

• Eye injuries: Eye injuries, as already noted, can cause traumatic cataract.

• Previous operations in the eyes: Some operations in the eyes, such as vitrectomy, can increase the risk of cataracts.

• Corticosteroids: Long -term use of corticosteroids, especially in high doses, is associated with an increased risk of cataract development.

• Alcohol: Excessive alcohol consumption can increase the risk of cataracts.

• Genetic predisposition: The presence of cataracts in a family history can increase the risk of its development.

• Inal meals: The lack of certain nutrients, especially antioxidants, can increase the risk of cataracts.

1.3. Symptoms of cataracts:

Symptoms of cataracts develop gradually and can vary depending on the type and stage of the disease. It is important to pay attention to any changes in vision and consult an ophthalmologist in a timely manner.

• Loud or blurry vision: This is one of the most common symptoms of cataracts.

• Difficulties with a vision at night: Cataract can worsen vision in conditions of low light, making it difficult to drive at night.

• Sensitivity to light and glare: Bright light can cause discomfort and glare.

• Dangling in one eye: In rare cases, cataracts can cause double vision in one eye.

• The need for a brighter light for reading: As cataract progresses, it may require a brighter light for reading and other activities.

• Frequent changes in the recipe for glasses: Cataract can cause frequent changes in the recipe for glasses.

• Deterioration of color perception: Colors may seem less bright and dull.

• The vision of the halo around the light sources: Galo may appear around light sources.

1.4. Cataract diagnosis:

Diagnosis of cataracts is carried out by an ophthalmologist using various examination methods.

• Assessment of visual acuity: A standard test for determining the clarity of vision at different distances.

• Slit lamp: Used for a detailed examination of the lens and other eye structures. Allows the doctor to evaluate the degree and type of cataract.

• Ophthalmoscopy: Inspection of the retina and optic nerve using a special device (ophthalmoscope).

• Tonometry: Measurement of intraocular pressure to exclude glaucoma.

• Sensitivity to contrast: Assesses the ability to distinguish objects with varying degrees of contrast.

• Test for color vision: Assesses the ability to distinguish colors.

• Refraction: Determining the need for vision correction using glasses or contact lenses.

Chapter 2: The role of vitamins and antioxidants in the health of the eyes

Vitamins and antioxidants play an important role in maintaining the health of the eyes and protecting against various diseases, including cataracts. They help neutralize free radicals, reduce inflammation and maintain the normal function of the eye cells.

2.1. Free radicals and oxidative stress:

Free radicals are unstable molecules that can damage the cells and tissues of the body, including eyes. They are formed as a result of normal metabolic processes, as well as under the influence of external factors, such as ultraviolet radiation, environmental pollution and smoking. Oxidative stress occurs when the balance between free radicals and antioxidants is disturbed, which leads to damage to cells and the development of various diseases.

2.2. Antioxidants: Eye Defenders:

Antioxidants are substances that neutralize free radicals and protect the cells from damage. They are found in various foods, especially in fruits, vegetables and berries. Some of the most important antioxidants for the health of the eyes include:

• Vitamin C (ascorbic acid): A powerful antioxidant that helps protect the lens from oxidative damage. High concentrations of vitamin C are contained in the lens of the eye.

• Vitamin E (Tokoferol): A fat -soluble antioxidant that protects cell membranes from damage by free radicals.

• Beta-carotene: The predecessor of vitamin A, which also has antioxidant properties.

• Lutein and Zeaxanthin: Carotinoids, which are concentrated in the retina, especially in the makul (central part of the retina). They protect the retina from blue damage and oxidative stress.

• Selenium: A trace element that is a component of antioxidant enzymes.

• Zinc: A trace element that is necessary for the normal function of enzymes involved in antioxidant protection.

• Glutathione: A powerful antioxidant that is synthesized in the body. He plays an important role in protecting the lens from oxidative damage.

2.3. Eye vitamins: scientific data

Numerous studies have shown that certain vitamins and antioxidants can play a role in the prevention and slowdown of cataract progression.

• AREDS и AREDS2: Two large clinical studies conducted by the US National Institute (Nei) of the United States showed that taking certain vitamin additives can slow down the progression of age -related macular degeneration (VMD) – another common eye disease. The Areds formula contained vitamin C, vitamin E, beta-carotene, zinc and copper. The Areds2 formula replaced beta-carotene with Luthein and Zeaksantin, as it was shown that beta-carotene increases the risk of lung cancer among smokers. Although these studies were focused on the VMD, they also showed that vitamins and antioxidants can be useful for the health of the eyes in general. Some studies suggest that the AREDS/AREDS2 formula can have a favorable effect on cataracts, although additional studies are required to confirm this.

• Studies of vitamin C: Some studies have shown that the high level of vitamin C in blood plasma is associated with a lower risk of cataract development.

• Studies of vitamin E: Some studies have shown that vitamin E can help protect the lens from oxidative damage.

• Research Lutheina and Zeaksanthin: These carotenoids, as shown, protect the retina from damage to blue light and oxidative stress. They can also help improve visual acuity and reduce the risk of cataracts.

• Meta-analyzes and systematic reviews: Many meta-analyzes and systematic reviews appreciated the influence of vitamins and antioxidants on the risk of cataracts. Some of these reviews showed that taking certain vitamin additives may be associated with a lower risk of cataract development, but the results remain ambiguous and additional studies are required.
