Treatment for blurry vision depends on the cause. An optometrist will be able to diagnose the root of the problem with an eye examination and recommend an appropriate treatment. Your exam will usually consist of a Snellen eye chart test, slit lamp and measurement of spatial contrast sensitivity.
If you're short or long-sighted, treatment most commonly consists of corrective lenses. Another more invasive option is LASIK eye surgery. With this option, you may encounter temporary blurry vision after surgery, but this will hopefully clear up after a few days.
Multifocal contact lenses can also correct presbyopia. Those with astigmatism will be prescribed toric lenses.
Blurred vision, when temporary, can be caused by high blood sugar levels. High blood sugar levels can cause the lens of your eye to swell, which then affects your sight. To correct your vision, getting your blood sugar levels back to a healthy range is vital.
Depending on what’s causing the blurred vision, other treatments include eye drops and medications.
