Blurry vision
It is quite common that one of the common symptoms a person notices when he/she develops an eye condition Is blurry vision. Blurry vision is simply when your vision isn't clear or in focus. It can occur at far, near, all distances, at a particular time of the day, at the center of your vision, in only one eye, and in a lot more ways. It all depends on the cause.
What causes blurry vision?
Numerous eye conditions can cause blurry vision but we are going to talk about the most common of them. They are;
Refractive errors
Refractive errors are conditions where images are not in focus because they are not formed directly on the retina. This happens due to the shape of the eye and /or the curvature of the cornea.

Types of refractive errors
Myopia: This is also known as short-sightedness which means that a person with this condition can see objects at a shorter distance clearly because objects at far are not clear and not in focus. This is when images are formed in front of the retina due to the longer eye shape.
Hyperopia: this is also known as long-sightedness meaning that a person with this condition prefers to focus on objects that are at far and can't see near objects. This is because images are formed behind the retina.
Astigmatism: This is a refractive error that occurs due to an irregular curvature of the cornea.
Presbyopia is the gradual inability to focus on near objects due to aging.
Age-related macular degeneration: as the name implies, it is an aging process in the macula that causes central blurry vision.
Cataracts: it is the clouding of the lens inside the eye, vision is unclear and hard to see through.
Cornea Abrasion: This is when the cornea (front surface of the eye) is scratched due to trauma or vitamin deficiency. This abrasion leaves a scar that in turn causes vision to be blurry.
Eye infections: The eye could be exposed to bacteria, viruses, or fungi by air or by contact and cause an infection if not treated can cause blurry vision.
Blurry vision can also be sight-threatening especially when it is sudden and starts progressing rapidly.

What can cause this?
A sharp increase or spike in blood pressure.
Head concussion
A detachment of the retina.
If you notice a sudden blurry vision, it is advised to visit the eye clinic or hospital immediately.

How to prevent a blurry vision
Blurry vision can't be prevented, but you can help yourself by following the instructions given to you by your optometrist. Make sure you have regular eye examinations.

How is blurry vision treated?
Prescription glasses and contact lenses: if you have a refractive error, these will be given to you by your doctor to help correct them. It is important to note that glasses and contact lenses do not cure refractive error, they are corrective and vision is only clear when they are put on.
Medications: a medication will help clear a blurry vision only when it is due to an infection. After a comprehensive eye exam, your doctor will prescribe the right medication for your eyes
Other treatments depend on the underlying condition that has resulted in blurry vision.

Blurry vision is a broad topic and it is indicative of so many eye conditions, just to be sure, it is best to go for a comprehensive eye examination so that the right condition is being treated. Follow the instructions and advice given to you by your eye doctor.
