What Are Some Causes Of Blurry Vision?

Have you experienced blurry vision? Blurry vision is one of the most common concerns I see on a daily basis. There can be many different causes of blurry vision, which is why it is crucial to have a full visual assessment. We evaluate the visual system and the health of your eyes. It’s important to understand that blurry vision is different from a loss of vision in one or both eyes (especially if a sudden loss of vision is experienced).

An Optometrist is a primary eye care provider who can properly diagnose the cause of your blurry vision.

Some of the possible reasons that someone’s vision may become blurry are:

  1. Refractive Error


    This is the most common cause of blurry vision and may be corrected with glasses, contact lenses, and in some cases surgeries like LASIK or PRK. Refractive errors include nearsightedness (myopia), farsightedness (hyperopia), astigmatism and presbyopia.

  2. Cataracts


    Cataracts occur when the natural lens inside each eye becomes cloudy, like a frosty window. This often occurs later in life and is a natural part of ageing, though it must be monitored with routine eye examinations.

  3. Eye Floaters


    Floaters often cause temporary blurry spots that can drift in and out of your vision. New floaters must be assessed to ensure the retina has not been damaged, though it is most often a normal part of the ageing process.

  4. Dry Eye


    Dry Eye Disease (DED) often causes blurred and fluctuating vision due to the instability and altered composition of the tears that cover the eyes. You can also help slow this down by eating plenty of vegetables (read more about this here) and other foods rich in omega 3.

  5. Glaucoma


    Known as the “silent thief” of vision, glaucoma occurs when the optic nerve gradually becomes damaged over time. Routine eye examinations are crucial in the detection of glaucoma. This silent thief often has no symptoms in the early stages. 

  6. Diabetes


    Diabetes can cause small blood vessels to become leaky over time. As a result, there are many ways that it can cause damage to various structures in the eye, causing irreversible vision loss if not treated early. It is crucial for patients with Diabetes to have their eyes checked every year.

  7. Pregnancy


    Hormonal fluctuations that naturally occur with pregnancy may cause blurry vision due to a change in refractive error. This may sound strange, but it is common to have your sight regained after delivery. So, it is highly recommended to get a thorough eye examination if you experience a sudden change in your vision.

  8. Retinal Problems


    The retina consists of over one million nerve fibres, which connect directly to the brain, allowing us to make sense of our vision. Retinal swelling, bleeding and inflammation may have a variety of causes and consequences to your vision. Some retinal conditions that can cause blurry vision include Macular Degeneration (AMD), Epiretinal Membranes, Retinal Vein Occlusions and Macular Edema.

It’s important to remember that there are different factors and causes of blurry vision. Take a proactive approach and make sure to come and visit us for your regular checks!
