If fluctuations in your vision occurred, it is possible that it is normal and it is not. Gradual vision changes can be due to temporary conditions, eye issues that are developing, and health problems. There can be instances that vision gets blurry out of nowhere.
Consult with your eye doctor immediately if there is a gradual vision change to determine what is causing it. A new eyeglass prescription or progressive lenses may be needed.
The Reason Why Vision Gets Blurry
Vision can be temporarily blurry because of the following reasons:
- Cataracts cause vision to worsen over time. Restoration of vision can occur with the help of cataract surgery.
- A corneal abrasion can impact your ability to see clearly. Once the scratch is healed, the vision will return to normal.
- Dehydration can cause eye dryness and strain which eventually leads to blurry vision.
- Eye strain can sometimes make vision blurry.
- Hyperglycemia causes the cornea to swell which affects vision.
- Hyphema can cause vision to fluctuate. Seek an eye doctor immediately to prevent long term damage and possible vision loss.
- Intoxication can cause double vision, blurry vision, and dizziness.
- LASIK surgery causes blurry vision to occur after surgery but it will improve each day.
- Medication can cause eye dryness that causes blurry vision to occur.
- Migraines cause light and sound sensitivity and as you avoid stimuli, vision can get blurry.
- Pregnancy causes hormonal changes and shifts that can result in blurry or double vision.
- Sleep deprivation causes vision to fluctuate.
The Underlying Conditions in Fluctuating Vision
- Detached retina causes fluctuating vision because of the impact of the altered retina.
- Dry eye syndrome results in insufficient lubrication of eyes and there are cases of fluctuating vision too.
- Glaucoma has a symptom called “tunnel vision”.
- Iritis causes blurry vision due to the inflammation of the iris.
- Keratitis is when the cornea is inflamed and it causes a change in our vision.
- Macular degeneration occurs as you age.
- Macular holes hinder vision but it usually occurs in one eye only.
- Pink eyes have secretions that can cause blurry vision.
The serious health conditions that can cause fluctuating vision are the following:
- A brain tumor can be present if your blurry vision is accompanied by headaches, seizures, nausea, and personality changes.
- Diabetes causes corneal swelling which can cause blurry vision or blindness in extreme cases.
- Preeclampsia can result in blurry vision due to hormonal change.
- Stroke can make you experience blurry vision, dizziness, and disorientation.
