Eye cylinder is a refraction error in the eye and is not an eye disease or a decrease in eye health. A cylindrical eye or astigmatism is a matter of the eye’s ability to focus light. Cylinder eye is an eye condition that often occurs and is usually corrected with glasses, contact lenses, or surgery.
Cylinders are caused by eyes that are not really perfectly round and occur in almost everyone. For vision problems due to cylinders, the use of glasses, contact lenses, and other vision correction procedures can be a treatment for this case.
A person’s eyes are naturally shaped like a ball. Under normal circumstances, when light enters the eye, the light will refract, or turn evenly and directed to create a clear view of the object.
The eyes of a person with cylindrical eyes are not perfectly rounded, or they may be surfaces like soccer balls that are not too flat, or the back of a spoon.
In a cylindrical eye, when light enters the eye, the light will be refracted in more than one direction, so that only a portion of the object can be focused simultaneously. Objects at certain distances can appear blurred and bumpy, even the sufferer is unable to see straight lines.
Cause of Cylinder Eyes
What causes cylindrical eyes?
Cylinder eyes are a natural factor that often causes blurred vision because objects that are seen are distorted. This is usually related to imperfect corneas. The exact cause is unknown.
Cylinder eyes occur when there is irregular corneal curvature, lenses, or both.
The cornea is a layer of transparent tissue that covers the front of the eye. It transmits and focuses light to the back of the eye while protecting the eye from infection and damage. A perfectly curved cornea can bend, or refract light properly when entering the eye.
In someone with astigmatism, the cornea is often egg-shaped with two different curves than perfectly round. This is sometimes known as corneal astigmatism.
Astigmatism is a symptom of deviation in forming a shadow on the lens of one’s eye. The existence of two different curves makes light rays focus on two points on the retina, not one.
This causes blurred vision and sometimes double vision, if the cylinder eyes are severe. It is not clear why some people are born with a cornea that isn’t curved properly, but there may be a genetic component.
A higher percentage of babies born prematurely have cylindrical eyes, compared to those born closer to their time period. Certain types of surgery or eye injuries that cause scarring of the cornea can cause cylindrical eyes.
Keratoconus is a degenerative disorder of the eye where the cornea gradually wears off and changes into a more conical shape. This can cause a condition known as irregular cylindrical eyes.
Cylinder Eye Symptoms
What are the symptoms of cylinder eyes?
People with astigmatism are often unaware that they have blurred vision so that it often leads to eye fatigue. Therefore, it is necessary to understand what the characteristics of the cylinder eyes are.
Patients with astigmatism need to schedule an eye examination if symptoms begin to feel, such as vision objects that are shaded, dizzy, and the eyes are often tired after seeing close or far.
The following are the signs and symptoms of astigmatism:
- Vision blurred or distorted at all distances
- Squinting too much
- Eye strain, especially when the eyes have to focus for a long time, such as reading from paper or a computer monitor
- Trouble driving at night
A person with these symptoms may not have cylindrical eyes, but it is a good idea to do an eye test to check.
Cylinder Eye Diagnosis
How to diagnose cylinder eyes?
Ophthalmologists can diagnose astigmatism with a thorough eye examination. Cylinders may occur with other vision problems such as the minus eye or the plus eye. Because the cylinder can increase slowly, you should visit an ophthalmologist every time you feel a change in vision.
Treating Cylinder Eyes
How is the treatment of cylinder eyes?
Nearly all “normal” cylindrical eye levels can be corrected with eyeglasses that are prescribed correctly or contact lenses that are prescribed correctly.
Specifically for people with mild cylindrical eyes, corrective lenses may not be needed at all, provided there are no other eye conditions such as minus or plus eyes. If the cylinder level is moderate to high, corrective glasses or contact lenses may be needed.
Cylinders can also be associated with abnormal conditions that affect the cornea, such as keratoconus, but this is rarely the case. When this occurs, this condition is more effectively treated with rigid gas permeable contact lenses or corneal procedures.
glasses or contact lenses. Cylindrical eye correction will usually be easy to do with the use of glasses or special soft contact lenses called toric lenses, which can be prescribed. Soft toric lenses have greater folds of light in one direction than in another.
Another option, especially for heavy cylinders, is gas-permeable rigid contact lenses. After conducting various tests, the eye doctor will determine the ideal prescription for the cylindrical eye.
- Refractive operation Another method for correcting cylindrical eyes is changing the shape of the cornea through refractive or laser eye surgery. There is more than one type of refractive surgery, and special treatment is recommended individually. Refractive surgery requires a healthy eye free from retinal problems, corneal scars, and eye disease.
As technology advances, it is strongly recommended to try all options and possible alternatives before deciding on a biased operation.
