Blurry vision refers to vision where there may be fuzzy or hazy lines instead of clear and sharp borders. It can cause navigation difficulty resulting in issues with driving, reading, and writing. Blurry vision doesn’t only affect the line of sight, but also parts of the entire vision. This can involve the peripheral vision.
Blurry vision can affect one or both eyes. Although blurry vision may seem trivial to most, it is important to seek medical attention if the blurry vision is accompanied with loss of muscle control on one side of the boy, severe headache, issues with speech, loss of vision, and facial drooping. The above symptoms are consistent with a stroke and warrants emergent care by professionals.
The diagnosis of blurry vision can be diagnosed via the patient’s history and physical examination performed by the physician. Eye tests such as the use of an eye chart, refraction test, ophthalmoscopy, tonometry, and slit lamp examination may be necessary. Blurry vision is treated based on the underlying cause.
Blurred Vision Cause #1: Atropine
Atropine is a type of medication used in the treatment of pesticides and nerve agent poisonings. It also helps to decrease heart rate and lowers saliva production during surgery. Used as an eye drop, it can treat uveitis and amblyopia.
Large doses help with the treatment of certain poisonings. Side effects of atropine use include urinary retention, large pupils, constipation, dry mouth, and tachycardia. One of the main side effects of atropine include blurry vision if used topically on the eye.
