Blurry vision is one of the most common reasons behind visiting an eye specialist. Your eyes lose sharpness and you are unable to see the objects and their detailing distinctly. Several reasons account to blurriness in vision which could range from eye problems to general health disorders.
Causes of blurred vision
Some eye disorders that lead to haziness in vision are:
- Nearsightedness- myopia
- Farsightedness- hyperopia
- Corneal Ulcer
- Inflammation of iris
- Inflammation of cornea
- Age related macular degeneration
- Renal detachment
- Presbyopia- diminishing ability to focus with age
- Eye infection, inflammation or injury
- Inflammation in the optic nerve-optic neuritis
Health disorders can also lead to blurred vision and they are:
- Stroke or transient ischemic attack
- Brain tumour
- Migraine headaches
- Polymyalgia rheumatic
- Trauma in the head
How is the vision affected?
Your vision may be blurry in one eye (unilateral blurred vision) or in both the eyes (bilateral blurred vision). You may either face problem in seeing the nearby objects clearly or the far objects would appear blurry. Some people might also have blurred vision for short and long distance simultaneously. Lack of sharpness in vision can be annoying.
Symptoms associated with blurred vision
If you have an underlying health or eye disorder, then you may also be experiencing few other symptoms which could be
- Pain, itching, dryness in eyes
- Bleeding from eyes
- Teary and redness in eyes
- Discharge from eyes
- Sensitivity to light
Note: The aforementioned symptoms differ from one individual to another and are completely dependent on the cause. They may not necessarily exist.
When to see a doctor?
You must fix an appointment with an ophthalmologist if you are unable to focus clearly on objects and see everything hazy.
Diagnosis of blurred vision
You need to explain to your doctor what kind of problems you are facing and the symptoms you are experiencing.
Your doctor will consider checking your ocular history and ask you several questions regarding vision, general health and work and lifestyle.
Depending upon the symptoms, you need to undergo eye tests pertaining to the functions and anatomy of your eyes. Some common tests for blurred vision are:
Visual acuity tests which include refraction test using a Snellen eye chart, slit lamp examination, measuring intraocular pressure (tonometry), etc.
Anatomical tests involve systematic checking of every eye part. You doctor will also look for trauma, inflammation and infection in the eyes.
Treatment of blurred vision
The treatment depends on the underlying condition of the eyes. Since the most common reason behind blurriness in vision is refractive error, it’s eliminated with corrective lens. You need to wear the glasses to regain clarity in eye sight.
Eye drops and anti-inflammation medications are also prescribed to treat infections and inflammations.
Your doctor will advise you to keep your eyes clean. You can splash water in a gap of an hour and avoid straining your eyes.
Eye surgery may also be suggested to treat an underlying eye disorder with the purpose of restoring normal vision.
It’s important to get your eyes checked as a part of your routine check up because sometimes you are not aware of the fact that you need a corrective lens. This way not only your eyesight improves but you also become less susceptible to eye disorders in the future.
