Blurry Vision: Causes, Symptoms, and Treatment

What kind of doctor treats Blurry Vision?
An ophthalmologist is a medical doctor who treats eye diseases. An optometrist is a doctor who examines eyes and fits glasses. These two are the main doctors for blurry vision. If a disease like diabetes causes the problem, your regular doctor helps too. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is blurry vision?
Blurry vision means the loss of sharpness of vision. Things look fuzzy, and you cannot see fine details. Your provider may ask whether it affects one or both eyes, and whether it is constant or comes and goes. Blurry vision is not a disease by itself. It is a sign that something is affecting the way your eyes focus or the health of your eyes.
Symptoms
The main symptom is seeing things out of focus. Other vision problems can show up with it:
- Double vision, when you see two images of one object.
- Hazy vision, or a glare or halo around bright lights.
- Distorted vision, when straight lines look wavy.
- Headaches or eye strain, when your eyes feel tired or sore.
- Trouble focusing when reading or looking at a computer.
Some people with blurry vision also notice floaters, which are small dark spots or squiggly lines that float across their vision.
Causes and who gets it
Many things can cause blurry vision. Refractive errors are the most common type of vision problem. They happen when the shape of the eye keeps light from focusing correctly on the retina, the light-sensitive layer of tissue in the back of the eye. The four common types are nearsightedness, which makes far-away objects look blurry; farsightedness, which makes nearby objects look blurry; astigmatism; and presbyopia, which makes it hard to see things up close as you get older.
Eye diseases can cause blurry vision too. Cataracts, which are cloudiness of the eye lens, cause poor night vision and halos around lights. Glaucoma is increased pressure in the eye. Macular degeneration causes blurred vision, especially while reading. Diabetes can also damage the eyes. Other causes include eye infection, inflammation, or injury. Some medicines may also affect your vision.
How doctors diagnose it
Eye doctors find the cause of blurry vision with a comprehensive eye exam. The exam is simple and painless. You read letters on a chart, and the doctor may use eye drops to widen your pupil and check for other eye problems. Tests may include a dilated eye exam, a slit-lamp examination, a refraction test for glasses, and tonometry, which measures the pressure inside the eye.
Treatment
Treatment depends on the cause. Eyeglasses are the simplest and safest way to correct refractive errors. Contact lenses also correct refractive errors. Some types of surgery, like laser eye surgery, can change the shape of the cornea, the clear outer layer of the eye, to fix refractive errors. Eye diseases such as cataracts and glaucoma need their own treatment, and surgery may be needed for some conditions. If a medicine seems to be affecting your vision, do not stop or change it without talking to your provider.
When to see a doctor
See a provider if you have any problems with your eyesight. Call 911 or go to the emergency room right away for sudden blurred vision with eye pain, especially if the eye is also red. A red, painful eye with blurred vision is a medical emergency. Get the same emergency help for partial or complete blindness in one or both eyes, double vision, a sudden shade or curtain over your vision, or a sudden increase in floaters or flashes of light. These can be signs of retinal detachment, which can cause permanent vision loss without quick treatment. Also call 911 if blurry vision comes on suddenly with weakness or numbness on one side of the body, a drooping face, trouble speaking, confusion, or fainting.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. This kind of doctor can check your overall health, since diseases like diabetes and high blood pressure can affect your eyes. They can also recommend how often you need eye exams.
Common questions
Can blurry vision be normal?
No. Blurry vision is common, but it should not be ignored. Refractive errors are the most common type of vision problem, and more than 150 million Americans have one. Many do not know they could be seeing better, which is why eye exams matter.
When is blurry vision an emergency?
Call 911 or go to the emergency room if blurred vision comes on suddenly with eye pain and a red eye. Sudden blindness, double vision, a curtain over your vision, or many new floaters are also emergencies. Quick treatment can protect your vision.
Can glasses fix all blurry vision?
No. Glasses fix refractive errors, which are a very common cause. But blurry vision from eye diseases may need drops, other treatment, or surgery. Your eye doctor can find the cause and talk over your options with you.
How often should I get my eyes checked?
It depends. People with known eye problems or conditions like diabetes or high blood pressure need earlier and more frequent exams, so ask your provider how often you need them. Regular checkups from an ophthalmologist or optometrist are important.
