When you have trouble seeing an object, maybe you will guess whether your condition is minus, plus, or cylinder eyes? Difficulty seeing straight lines clearly is often associated with cylindrical eye disorders. However, there are still other signs and symptoms that fall into the characteristics of a cylinder eye. Consider the following explanation to distinguish the characteristics of cylindrical eyes from other visual disorders.
What are the characteristics of a cylinder eye?
Cylindrical eye (astigmatism) occurs due to the shape of the cornea or lens on the inside of the eyeball that does not have complete curvature. This condition causes the eye to be unable to focus light on the retina (refractive error) so that objects cannot be seen clearly.
You may experience cylindrical eyes to a different degree in each eye. This means that only one eye may have a cylinder, while the other may not. In some cases both eyes may become cylindrical, but of different severity.
Cylindrical eyes are usually experienced in conjunction with nearsightedness (myopia) or farsightedness (hypermetropy). Most people with cylinder eyes, especially children, find it difficult to realize if they have this visual disturbance.
Therefore, it is important for you to recognize the characteristics of a cylinder eye so that this visual disturbance can be treated immediately. Here are some of the symptoms of a cylindrical eye:
1. The vision is blurry or blurred
Blurred vision is a common sign indicating damage to the eye. Normally, the shape of the cornea or lens inside the eyeball is perfectly round. This aims to even out the spread of light coming to the eye so that objects can be seen clearly.
However, in a cylindrical eye, the curvature of the eye lens is not completely formed. This difference in the shape of the curve can change the incoming light or refract it back in another direction. Finally, light cannot fall directly on the retina.
This condition causes vision in the eye to become blurry and unclear. People with cylinder eyes usually have difficulty seeing straight lines or surfaces. In addition to appearing blurry, the characteristics of the cylinder eye sometimes show that objects can appear shaded.
2. Eyes tired and difficult to focus
Because the eyes have to work extra hard because of the damage, the eyes get tired easily when they see. Especially when you have to focus for a long time on an object, such as reading, staring at an electronic screen, working at a computer, or viewing from a distance.
This characteristic of cylindrical eyes causes the eyes to sting, itch, or water, so they need to be rested by closing the eyes for a moment. Tired eye conditions make it difficult for a person to focus on observing or doing something.
According to the NHS, when these cylindrical eye symptoms occur in children and are not treated promptly, they can lead to lazy eye complications.
If the child often complains that his eyes feel tired and sore when focusing on watching or reading for a long time, immediately do an eye vision examination to detect cylindrical eyes early.
3. Often squinting
The next characteristic of cylindrical eyes is that they often squint when looking at them from near or far away. It is difficult to see an object, often makes you have to squint until the object is quite clear.
Symptoms of these cylindrical eyes can be clearly seen when you have certain vision disorders. For example, those of you who are nearsighted usually can still see objects up close clearly, but cylinder eyes can cause the vision of near objects to become blurry.
4. Headache
In some cases, severe cylindrical eye conditions can also cause headaches. This usually occurs because the eye is working too hard to see objects clearly. Even though the eye has decreased its ability to see due to cylindrical eyes.
Headaches due to cylindrical eye symptoms are usually accompanied by eye fatigue, especially if these have been experienced frequently. When a headache appears, the eyes usually feel tense too. The pain in the head can get worse if the cylinder is not treated immediately.
In conditions of mild astigmatism, usually the eyes can still adjust. However, wearing contact lenses or glasses can be a way to treat the annoying cylindrical symptoms. In addition, maintaining eye health is also important to prevent cylindrical eyes from getting worse.
