Causes Of Blurry Vision & Ways To Prevent It

When it comes to your eyes, there are a variety of issues that can arise, and the necessity of prescription glasses in these situations should never be neglected. The eyes are one of the most delicate parts of the body, and they are prone to a variety of issues throughout the course of a lifetime, especially if they are not properly cared for. Prescription glasses can help people avoid many of the most frequent vision issues, and they also have a lot of other advantages. When blurry vision becomes a problem, there are five main causes to look out for.

Straining Of The Eyes

In today’s day and age, we spend a lot of time on our computers, smartphones, tablets, TVs, and other electronic devices. With so much screen time, comes strain on the eyes. It can occur over a period of time and can be avoided with proper breaks between screen time and the use of blue light glasses that help block and filter out the blue light that’s given off digital screens. 


For many people, migraines can be severe, painful, and strenuous, causing not only a headache but also eye aches that can lead to blurry vision. Ways to avoid migraines that can cause impaired vision are steering clear from flashing lights, long-term use of digital screens, and anything that can give a sensory overload. Prescription glasses are proven to help eliminate migraines at the root along with reducing the symptoms associated. 

High Blood Pressure

When a person has high blood pressure, their eyes tend to enlarge or swell due to the blood sugar levels going up. When your eyes swell, it can change the shape and structure of the eye and how well you can see and focus. Blurry vision is also a symptom of someone who may be pre-diabetic, so its best to seek assistance from your medical provider if blurry vision is a prolonged issue. 

Optic Nerve Inflammation

Optic nerve inflammation, often referred to as optic neuritis, occurs when the optic nerve, a bundle of nerve fibers that transmits visual data from the eye to the brain, is swollen and damaged. Characteristics of optic nerve inflammation are pain and discomfort while moving the eyes, temporary loss of vision, vision distortion, and in worst scenarios, blindness. There are a series of treatments that can assist with optic neuritis and also patients with glaucoma which are medicated eye drops, oral medicine, and laser therapy.

Scratched Eyes

Anything that comes into contact with the naked eye has the potential to scratch it, which might include dust particles in the wind or debris that flies into the eye inadvertently. The most common of scratches in the eyes are corneal abrasions that can cause the eye to become red, irritated, itchy, swollen, sensitive to light, and more. If scarring occurs, it can cause life-long issues such as blurry vision or impairment. 

Fortunately for the majority of individuals, most of the causes of blurred or impaired vision do not pose a long-term threat to vision. Nevertheless, when in doubt, get your eye checked out!
