Supplements and dry eye syndrome

Dry eye syndrome is an increasingly common disorder, affecting a large number of people worldwide. Caused by insufficient tear production or excessive tear evaporation, this condition can cause significant discomfort and affect the quality of daily life. In this context, dietary supplements are a promising option to alleviate symptoms and improve ocular health. In this comprehensive guide, we review the best supplements available to counter dry eye, analysing their benefits, mode of action and expert recommendations for optimal use.

Introduction to Dry Eye Syndrome

Dry eye syndrome is a widespread eye condition that is often overlooked despite its significant impact on many activities of daily living. This section provides a fundamental overview to better understand this condition, its causes, symptoms and consequences on quality of life.

What is Dry Eye Syndrome

The dry eye syndrome or Dry Eye Disease (DED) is a disorder caused by insufficient tear production or excessive tear evaporation.

Both hyposecretive and evaporative dry eye result in insufficient lubrication and moisture on the surface of the eye.

Tears

Tears are among the constituents of tear film, the film that covers the corneo-conjunctival surface and forms the interface between the eye and the external environment. The tear film consists of three layers: lipid, aqueous and mucous.

Tears are essential for keeping the eyes healthy, offering natural protection against infection and irritation.

They contain mainly water, but also electrolytes, proteins, fats and an important antibacterial enzyme, the lysozyme.

They are produced by the main and accessory lacrimal glands and perform numerous functions:

- lubricate the eye, creating a smooth surface on the cornea on which the eyelids can slide easily.

- nourish the cornea, which, being devoid of blood vessels (avascular), receives nutrients and oxygen precisely through the tear fluid.

- protect the eye by removing all waste substances and not allowing germs to take root.

A very important characteristic of the tear film is theosmolarity, which chemically is the concentration of osmoliparticles that contribute to the osmotic pressure of the tear film. Recent studies have shown that an increased osmolarity of the tear film (hyperosmolarity) is one of the main causes of inflammation of the ocular surface and a number of related damages.

Symptoms and Causes of Dry Eye

Many people experience symptoms such as burning, redness and a foreign body sensation in the eyes. Although not always serious, this condition can become debilitating if not managed properly. It is crucial to recognise the symptoms early to prevent chronicisation and to avoid more serious complications.

Correct identification of dry eye syndrome is the first step towards effective treatments. Early diagnosis and appropriate treatment approaches can greatly improve the quality of life of those affected.

Several factors can contribute to the onset of dry eye syndrome.

Common causes include advanced age, prolonged use of digital screens and exposure to adverse environmental conditions. The use of certain medications and underlying medical conditions can also exacerbate the problem.

Symptoms vary from person to person, but often include:

  • Burning and itching
  • Feeling of sand in the eyes
  • Blurred vision

Understanding causes and symptoms is essential to determine the most appropriate treatment. Identifying personal triggers can help tailor treatment for maximum benefit.

Impact on Quality of Life

The dry eye syndrome can affect multiple aspects of daily life. Affected persons may find themselves constantly uncomfortable, with a reduced ability to concentrate and perform activities that require clear vision.

Continuous discomfort can lead to frustration and stress, further worsening the symptoms. Even simple activities such as reading, working on the computer or driving can become challenging.

The psychological impact should not be underestimated. Improving the management of dry eye not only alleviates physical symptoms, but also general well-being, improving the ability to enjoy daily activities without visual limitations.

Importance of Supplements

Food supplements are a valuable support in the treatment of dry eye syndrome.

Omega-3 supplementsfor example, are known to reduce inflammation and improve tear quality. Others, such as the vitamin Asupport the health of the ocular surface.

These supplements work mainly by providing essential nutrients that may be lacking in the daily diet.

Incorporating supplements into the daily routine can lead to a significant improvement in dry eye symptoms. However, it is important to consult a health professional before starting any new supplementation regime.

Scientific Research and Supplements

Numerous studies support the use of supplements for dry eye.

More scientific research shows that Omega-3 can improve tear film stability, significantly reducing dry eye symptoms.

One study showed that participants taking Omega-3 supplements experienced a 20% reduction in symptoms compared to the control group. Other studies confirm the effectiveness of antioxidants in protecting the ocular surface from oxidative stress.

This scientific evidence also underlines the importance of a balanced diet supplemented with specific nutrients for ocular well-being.

Safety and Considerations

Before starting to take any dietary supplements, it is advisable to consult a doctor or nutritionist. This helps to avoid side effects and ensure that the supplements you choose are suitable for your specific needs.

In fact, the use of supplements must be approached with care, as safety is paramount, as is understanding potential interactions with other drugs one routinely takes. It is also essential to choose quality products from reputable manufacturers.

Adhering to recommended doses and following the manufacturer's instructions is crucial. Excessive intake of supplements can cause unwanted side effects, so moderation is the key to safe and effective use.

Types of Supplements for Dry Eye

There are several types of supplements that can help in the management of dry eye.

Omega-3 and Benefits

Omega-3s are essential fatty acids known for their effects anti-inflammatory.

Omega-3 is found in foods such as oily fish and flaxseed, but it is often difficult to obtain sufficient quantities from diet alone.

Their positive effects at a glance:

  • Promote tear production and improve tear composition
  • Reduce ocular inflammation
  • They support general eye health

Supplementation with Omega-3-containing nutraceuticals can be a practical alternative to ensure a steady supply, but it is important to choose high-quality supplements to maximise the benefits.

Vitamin A and Ocular Health

The vitamin Aalso known as retinol, retinoic acid, retinaldehyde, is an important nutrient for vision, tissue growth and differentiation, cell division, reproduction and immunity. It is also known for its antioxidant properties.

Vitamin A is introduced into the body through food in two forms:

  • directly as vitamin A (retinol)through foods of animal origin
  • as provitamin A (carotenoids), a precursor of the vitamin, through foods of plant origin

The precursor is converted into vitamin A within the portion of the intestine called the dim and then goes to the liver which will, depending on the body's needs, either store it or release it little by little bound to a protein that transports it into the bloodstream. The two sources of vitamin A are not equivalent; the body absorbs retinol from animal sources better

Including vitamin A in the diet can prevent dryness and improve the integrity of the ocular surface. Consulting a health professional to determine the appropriate dosage is always advisable.

Antioxidants and Eye Protection

The antioxidants, such as vitamin C and E, play a crucial role in protecting eye cells from oxidative damage. This damage can contribute to inflammation and worsening of dry eye syndrome, as:

  • Protect eye cells from free radicals
  • Reducing the risk of inflammation
  • They support general eye health

Choosing the right supplement

When choosing a supplement for dry eye, there are several factors to consider. These include the quality of the product, the recommended dose and the origin of the ingredients. The presence of quality certifications is also crucial.

It is therefore necessary:

  • Assessing the specific needs of the individual
  • Consider any allergies or interactions with other drugs
  • Consult a health professional for personalised advice

A wise choice can make all the difference in treating symptoms and improving overall ocular health.

Advice from the Experts

Experts recommend basing the choice of supplements on scientific evidence and clinical studies. Choosing supplements that are backed by solid research can ensure greater efficacy and safety.

We also recommend:

  • Prefer supplements with natural ingredients
  • Opt for independently certified products
  • Follow your doctor's recommendations for safe use
