(cornea)
szaruhártya
(anatomy) the transparent layer that covers the outside of the eyeball
The cornea is the transparent, dome-shaped layer at the front of the eye that covers the iris and pupil. It plays a crucial role in refracting and focusing light onto the retina, allowing us to see clearly. The cornea is composed of specialized cells and is responsible for most of the eye's focusing power. It is essential for maintaining the integrity of the eye and protecting it from external elements.
(szivárványhártya)
írisz
(anatomy) the round colored portion of the eye around the pupil and behind the cornea
The iris, a thin circular structure in the eye, contains pigments that give it color and helps control the amount of light that enters the eye through the pupil. It acts like a diaphragm, expanding or contracting to adjust the size of the pupil and regulate the amount of light reaching the retina. The unique pattern and color of the iris are used for identification purposes, making each person's iris distinct and individual.

lencse
(anatomy) the clear elastic part of the eye that concentrates light in order for things to be seen clearly
The lens, a flexible and transparent structure in the eye, contributes to the process of focusing light onto the retina. It works in conjunction with the cornea to refract incoming light, allowing for the formation of clear images. By adjusting its shape, the lens accommodates varying distances, enabling us to see objects up close or at a distance with clarity. Its function is vital for visual acuity and the perception of depth and detail.

pupilla
(anatomy) the small round black area in the center of the eye, through which light enters
The pupil, a crucial part of the eye, acts as a gateway for light to enter the inner structures. It is a dynamic, adjustable opening surrounded by a colored iris. The size of the pupil is regulated by the iris muscles, which contract or dilate in response to varying light levels. In bright conditions, the pupil constricts to limit the amount of light, protecting the delicate structures of the eye. Conversely, in dim lighting, the pupil dilates to allow more light to enter, enhancing visual sensitivity. Through its adaptable nature, the pupil plays a vital role in regulating the amount of light reaching the retina, ensuring optimal vision in different environments.
(ideghártya)
retina
(anatomy) the sensory membrane at the back of the eye that transmits light signals to the brain through optic nerves
The retina, located at the back of the eye, is a thin, light-sensitive layer that plays a crucial role in vision. It contains specialized cells called photoreceptors, including rods and cones, which convert light into electrical signals. These signals are then transmitted to the brain through the optic nerve, where they are processed and interpreted as visual information. The retina's intricate structure and arrangement of photoreceptor cells enable the perception of colors, shapes, and details, forming the foundation of visual perception. It acts as a vital sensory component, allowing us to see and perceive the world around us.

sclera
the tough, outer layer of the eye that helps protect and maintain the shape of the eyeball
The sclera, often referred to as the "white of the eye," is the tough, protective outer layer that covers most of the eyeball. It is composed of dense connective tissue and helps maintain the shape and integrity of the eye. The sclera provides attachment points for the muscles that control eye movement and serves as a barrier to protect the delicate structures inside the eye. It also plays a role in maintaining eye pressure and providing structural support. While it is primarily white, the sclera may have a slightly bluish tint in some individuals. Overall, the sclera serves as a vital component of the eye, contributing to its overall function and protection.
(szemhéjszőr)
szempilla
any of the short hairs that grow along the edges of the eyelids
Eyelashes are short, curved hairs that grow along the edges of the eyelids. They serve as a protective barrier for the eyes, helping to keep out dust, debris, and foreign objects. The eyelashes are also essential in preventing excessive light from entering the eyes, reducing glare, and providing shade. Additionally, eyelashes play a crucial role in enhancing the aesthetics of the eyes, adding definition and framing to the face. Their delicate structure and sensitivity make them responsive to touch, triggering a reflex action to blink when something comes into contact with them. Overall, eyelashes contribute to the health, function, and beauty of the eyes.
(felső szemhéj)
szemhéj
either of the upper or lower folds of skin that cover the eye when closed
The eyelid is a movable skin fold that covers and protects the delicate structures of the eye. It consists of thin layers of skin, muscles, and connective tissue. The primary function of the eyelid is to shield the eye from external factors such as dust, light, and foreign objects, while also helping to distribute tears across the surface of the eye. The eyelids can blink rapidly to keep the eye moist and to clear away any irritants. Additionally, the eyelids play a role in expressing emotions, such as blinking in response to bright light or closing during sleep.
