Blurred vision is a common condition where the sharpness or clarity of vision is reduced. It can occur in one or both eyes and can be temporary or chronic. Blurred vision may be caused by a variety of factors, including:
- Refractive errors: This includes nearsightedness, farsightedness, and astigmatism, which can all cause blurred vision.
- Presbyopia: This is a normal age-related change that causes the lens of the eye to become less flexible, leading to blurred vision when reading or doing close work.
- Eye infections or inflammation: Infections or inflammation of the eye can cause blurred vision, as well as other symptoms such as redness, itching, and discharge.
- Cataracts: A cataract is a clouding of the eye's lens, which can cause blurred vision, sensitivity to light, and difficulty seeing at night.
- Glaucoma: This is a group of eye conditions that damage the optic nerve and can cause blurred vision, along with other symptoms such as eye pain and headache.
- Diabetes: Diabetes can cause damage to the blood vessels in the eye, leading to blurred vision and other vision problems.
If you are experiencing blurred vision, it is important to see an eye doctor for a comprehensive eye exam. Treatment for blurred vision will depend on the underlying cause, but may include prescription eyeglasses or contact lenses, medication, surgery, or lifestyle changes such as managing blood sugar levels in the case of diabetes.
