There are multiple different eye shapes, such as hooded eyes, downturned eyes, and upturned eyes, among many others.

Some people are unaware of the exact eye shape they have, but it’s fairly easy to determine your eye shape on your own.
Vision and eye shape are usually independent of each other. However, certain eye shape variations may affect vision. Keep reading to find out how you can determine what your eye shape is.
How Does Vision Work?
Vision is a complex process. Rays of light go through the cornea and into the eye. The cornea refracts these rays as they pass through the pupil.
The rays then go through the lens of the eye where they are further bent. From here, they focus on the retina at the back of the eye.
There are light-sensing nerves in the retina referred to as cones and rods, based on their distinct shapes. The cones are at the center in the macula of the eye. They allow people to have color vision and sharp central vision. The rods are outside the macula, and they allow for peripheral vision.
The cones and rods take light and turn it into electrical impulses. These impulses travel to the brain via the optic nerve. This is when an image is produced.
The Different Eye Shapes
People often consider the shape of their eyes for makeup application. However, there are several other reasons to know the shape of your eye.
- Deep-set eyes: Deep-set eyes make the brow bone appear more prominent since they are deeper in the skull and larger.
- Monolid eyes: This type of eye does not have much of or any crease. On the surface, they are flat.
- Hooded eyes: The lid appears smaller with this type of eye. This is because there is an extra layer of skin that is over the crease, which droops down.
- Protruding eyes: With this type of eye, the eyelids appear to project outward in the eye socket area.
- Upturned eyes: This type of eye has an almond shape. At the outer corner, there is a natural lift.
- Downturned eyes: At the outer corners, this type of eye has a slight drop.
- Close-set eyes: When the eyes are close set, the space between them is less than one eyeball width apart.
- Wide-set eyes: With wide-set eyes, the space between them is more than one eyeball width.
What Is My Eye Shape?
To determine eye shape, there are a couple questions to answer. If you can see your crease, there is a second question to answer. If the crease is not visible, you have monolid eyes.
If there is a visible crease, use the following to determine what your eye shape is:
- If the colored part of the eye has a little white showing and the crease is visible, your eyes are round.
- If the eye’s outer corners turn down, your eyes are downturned.
- If you have a crease that is not visible due to a skin flap, you have hooded eyes.
- If the iris touches the bottom and top of the eyelid and the crease is visible, the eyes are almond-shaped.
- If there is a flick upwards of the outer corners of the eyes, you have upturned eyes.
To determine structure abnormalities inside the eye, you need to visit an eye doctor. They can perform a comprehensive eye examination and additional tests, such as a slit lamp exam, as necessary to determine if there are issues with different eye structures, such as the lens, cornea, or retina.
How Eye Shape Affects Vision
When the lid droops, this could potentially affect vision. This is a condition referred to as ptosis. The upper eyelid border falls lower than normal. In severe cases, ptosis can interfere with vision by covering the pupil completely or partially.
It is possible for both or just one eye to be affected by ptosis. In some cases, this condition is present at birth. For other people, it can occur over time as a result of nerve problems or different muscle diseases, such as myasthenia gravis.
The affected eye can look smaller than it actually is. The crease between the eyebrow and upper eyelid can start to decrease. If the ptosis is drooping enough, the pupil becomes covered, which can completely or partially obstruct vision. This can cause someone to raise their eyebrow in order to see regularly. This could lead to tension headaches.
The treatment for ptosis depends on the underlying cause. There are surgical options to correct the drooping if it is age-related or a condition from birth.
The shape of the actual eyeball will affect vision.
It is possible for the eyeballs to be either shortened or elongated. An elongated eyeball is also referred to as myopia or nearsightedness. With this condition, people have difficulty seeing objects that are far away.
Nearsightedness usually does not affect the ability to use a smartphone or read a book. Only distance vision is affected. It is possible to experience headaches due to straining to see objects in the distance.
This condition may also occur as a result of the cornea having an abnormal shape. The cornea curvature is too much for the length of the eyeball. In some cases, the lens of the eye is too thick. Why the eyeball may get too long remains unknown.
A shortened eyeball is known as hyperopia or farsightedness. This condition makes it difficult to see objects that are close. For example, it may be difficult to read a computer screen or a menu. When this condition is significant, the blurriness may also affect distance vision.
In this case, the eyeball is shorter than what is considered normal. A shortened eyeball may also be used to describe a cornea with a curvature that is too slight. This can cause the rays of light that are entering the eye to focus behind the retina, making it difficult to see close objects.
Does Shape Affect Your Eye Color?
When you mention any eye color, you’re actually describing how the iris looks. Depending on your ancestry, your iris may be light blue, green, dark brown or any number of hues within this color spectrum.
But eye shape has nothing to do with the color of your iris. Genetics is the more plausible explanation for the differences in eye color evident in people with different ancestries or from different parts of the world.
Your genes will determine your eye color specifically by dictating the amount and quality of melanin in some of the tissue forming the iris. Researchers came to this conclusion after discovering that a greater proportion of the genes responsible for the pigmentation of the iris are involved in melanin generation, transportation, and storage.
Melanin influences color in various body organs, and people with high concentration of this pigment generally have brown eyes. If you have blue eyes, that’s because you have less amounts of melanin.
Your eye shape barely plays a role in determining the iris’s pigmentation.
You Can Change the Shape of Your Eyes
Eye shape can be altered, thanks to advancements in surgical and non-invasive optical techniques. Generally, some people have the outward appearance of their eyes changed for cosmetic reasons. Others change the shape to fix vision problems.
If you wish to change the shape of your eyes, there are options worth considering, including blepharoplasty and LASIK surgery.
Eye Shape and Your Personality
The notion that an individual’s eyes and personality have a close connection is deeply-rooted in many cultures. As per many of the ancient theories on eye shapes, you can look at someone’s eye and decide whether or not they can be trusted.
You only need to look closely and you might be able detect deeply-concealed malice or genuine love. For example, some people believe large eyes signify emotions that run deep. Going by this belief, individuals with large eyes are quick to trust people and many times end up being betrayed.
These notions about eye shapes and character traits have no scientific basis whatsoever. So, next time someone looks you into the eye, don’t be afraid they’re going to peep into your soul and accurately judge your personality.
There is is no evidence that eyes serve another purpose in the human body besides enabling us to see the beauty of the world around us.
Mostly an Aesthetic Issue
There are numerous eye shapes, and for the most part, eye shape is just an aesthetic issue.
