Ametropias

Ametropias are refractive disorders of the eye that affect its ability to correctly focus light on the retina. This can lead to blurred or distorted vision. The three main ametropias are:

The eye focuses light in front of the retina instead of on it, which results in clear vision of nearby objects but blurred vision of distant objects.

The eye focuses light behind the retina instead of on it, which causes a clear vision of distant objects but blurry vision of nearby objects.

The cornea or the lens have an irregular curvature, resulting in distorted vision of both near and distant objects.

Visual Diseases

There are numerous diseases and disorders that can affect visual health. Some of the most common eye diseases include:

They are characterized by the opacity of the lens, which can cause blurred vision, sensitivity to light, and difficulty seeing at night.

It is a disease in which the pressure inside the eye increases, which can damage the optic nerve and cause irreversible vision loss if not treated.

It is a condition in which the macula, the central part of the retina responsible for detailed vision, deteriorates over time, which can lead to a loss of central vision.

It is a complication of diabetes that affects the blood vessels of the retina, which can lead to vision loss if not treated.

It occurs when the eyes do not produce enough tears or when the tears are of poor quality, which can cause discomfort, redness, and blurred vision.

It is a disorder in which the eyes do not align properly, which can cause double vision and difficulty focusing on objects correctly.

Also known as "red eye", it is the inflammation of the conjunctiva, the transparent membrane that covers the white part of the eye and the inside of the eyelids, which can be caused by infections, allergies, and other irritants.

It is a condition in which the cornea thins and bulges outward in the shape of a cone, which can lead to distorted vision and astigmatism.

Ocular Health

Ocular health is essential to maintain a good quality of life and optimal performance in daily activities. Here are some key aspects to maintain eye health:

It is important to have periodic eye examinations, even if no visual problems are experienced. An ophthalmologist can detect eye conditions in the early stages when they are more treatable.

Protecting the eyes from ultraviolet (UV) radiation from the sun by using sunglasses that block at least 99% of UV rays can help prevent the development of cataracts and age-related macular degeneration.

Resting the eyes regularly, blinking frequently, and maintaining an appropriate distance when looking at digital screens can help prevent eye strain and dry eye syndrome.

A diet rich in antioxidants, vitamins and minerals, such as vitamins A, C and E, as well as zinc and omega-3 fatty acids, can benefit eye health. Including foods such as leafy green vegetables, fish, fruits, and nuts can be beneficial.

Smoking is associated with a greater risk of developing eye diseases such as cataracts, macular degeneration, and optic nerve damage.

When engaging in sports or work activities that may pose a risk to the eyes, wearing appropriate protective equipment, such as safety glasses, can prevent eye injuries.

Keeping health conditions like diabetes and hypertension under control can help prevent eye complications associated with these diseases.

Getting enough sleep and resting properly can contribute to good eye health, as fatigue and stress can negatively affect vision.

SDG

The SDGs are the Sustainable Development Goals. They are a set of 17 interrelated goals adopted by the United Nations General Assembly in 2015 as part of the 2030 Agenda for Sustainable Development.

To end poverty in all its forms everywhere, ensuring a dignified life and opportunities for all.

Ensure a healthy life and promote well-being for all ages.

Ensure inclusive, equitable, and quality education, and promote learning opportunities for all.

Achieve gender equality and empower all women and girls.

Promote sustained, inclusive and sustainable economic growth, full and productive employment, and decent work for all.
