- Blurry vision is a common eyesight problem, especially in the elderly.
- Blurriness could be a sign that your glasses or contacts prescription needs updating.
- A fuzzy vision can sometimes mean something more serious.
Having a blurry vision is a common problem, but knowing the reason behind it can help tell if you are experiencing the world in all its dimensions or not.
Here are common causes of blurry visions and what to do about them.
You need prescription glasses, or you need an updated prescription.
Nearsightedness, farsightedness, and astigmatism are the most common causes of blurry eyesight. These can be fixed with prescription glasses or contact lenses, and LASIK surgery.
You need reading glasses.
Presbyopia is a refractive error that causes trouble focusing on things that are close up. If you have presbyopia, eyeglasses, contact lenses, and surgery can help your vision.
You have conjunctivitis.
Pesky viruses usually cause conjunctivitis. Conjunctivitis goes away in one to two weeks without treatment, but if you have severe symptoms, consult your doctor.
You sleep with your contacts.
Sleeping with your contacts promotes the growth of infection-causing organisms and cause corneal ulcers and open sores on the cornea that can blur vision.
You have an eye infection.
Herpes keratitis is an eye infection caused by the herpes virus. Bacteria and fungi from an eye injury can also cause infection.
Eye drops and medications usually help.
You’re developing cataracts.
A cataract occurs when the lens in the front of the eye becomes blurry and blocks light reaching for the retina. Cataracts are often treated with surgery.
You’re developing glaucoma.
Glaucoma is caused by extra pressure in the eye, which damages the optic nerve. Treatments for glaucoma include prescription medications, laser treatment, and surgery.
You have macular degeneration.
People over 60 years old have a higher risk of damage to the macula. There is no treatment for this disease, but high doses of vitamins and minerals can slow its damage.
You have diabetes.
Diabetic retinopathy occurs when damaged blood vessels leak or extra blood vessels grow in the back of the eye and start bleeding.
Injections and laser surgery can help treat your vision.
You have high blood sugar.
High blood sugar can cause blurry vision. If you think you might have high blood sugar, see your doctor right away.
You have high blood pressure.
High blood pressure can cause a mini-stroke of the eye called vein occlusion, which usually strikes just one eye. Immediate medications can effectively treat the swelling.
You’re dealing with ocular migraines.
The spasm of the blood vessels that help the brain process visions causes ocular migraines, which can occur with or without a headache, and typically lasts under an hour.
You have a concussion.
Suffering from a concussion can cause vision issues, so see your doctor immediately for treatment.
You’re stressed out.
Stress can cause the pupils to dilate unnecessarily, while adrenaline can increase pressure on the eyes. Prolonged heightened stress levels can cause permanent vision loss. Preventing stress can help treat stress-related vision problems.
You have uveitis.
Uveitis is a group of diseases associated with auto-immune or infectious disease that is most commonly limited to the eye. Treatment can vary from antibiotics or antivirals for infectious causes to corticosteroids, and immune system modulators when the cause is auto-immune.
You have dry eye syndrome.
If your tear film is unhealthy, it will irritate your cornea, and light will be scattered rather than focused as it enters the eye, leading to blurred vision.
