Why is my eye sight blurry?

Understanding Blurry Vision: Causes and Solutions Explained

Have you ever experienced moments when your vision seems fuzzy or unclear? Blurry vision can be not only frustrating but also a potential sign of underlying eye health issues. Understanding why your eyesight goes blurry is the first step towards finding solutions to improve your vision. At PW Optics, our team of fully qualified Opticians and Optometrists is here to shed light on the causes of blurry vision and provide personalised solutions to help you see clearly again.

Blurry vision can occur for several reasons. It’s essential to determine the cause to address the issue effectively.

Why is my Eye Blurry when I Wake Up

  1. Dry Eyes: Overnight, tear production decreases, leading to dryness upon waking up. Dry eyes can cause blurry vision until normal tear production resumes.
  2. Corneal Edema: Fluid accumulation in the cornea overnight can cause swelling, leading to blurry vision in the morning. This may occur due to prolonged contact lens wear or certain medical conditions.
  3. Eyelid Issues: Conditions like blepharitis (inflammation of the eyelids) or meibomian gland dysfunction can disrupt tear production and lead to blurry vision upon waking.
  4. Eye Allergies: Allergens present in bedding or the sleeping environment can trigger allergic reactions, causing redness, itching, and blurry vision upon waking up.

Causes of Blurry Vision at the End of the Day

  1. Eye Fatigue: Prolonged screen time, reading, or performing close-up work throughout the day can strain the eyes, leading to blurry vision by the end of the day.
  2. Dry Eye Syndrome: Environmental factors, such as air conditioning or heating, can exacerbate dry eye symptoms over the course of the day, resulting in blurry vision.
  3. Contact Lens Discomfort: Extended wear of contact lenses or improper cleaning can lead to discomfort and blurry vision by the end of the day.
  4. Refractive Errors: Individuals with uncorrected refractive errors may experience worsening blurry vision as the day progresses due to eye strain and fatigue.

Why is my Vision Blurry in One Eye

  1. Refractive Errors: Differences in refractive error between the eyes can cause one eye to be blurrier than the other. This is common in individuals with significant differences in prescription between their eyes.
  2. Corneal Irregularities: Conditions such as keratoconus, where the cornea becomes progressively thinner and more conical in shape, can cause asymmetric blurry vision, often affecting one eye more severely.
  3. Eye Injuries: Trauma or injury to one eye can lead to blurry vision specifically in that eye. This may be accompanied by other symptoms such as pain, redness, or swelling.
  4. Eye Diseases: Certain eye diseases, such as optic neuritis or retinal detachment, can cause sudden onset blurry vision in one eye. These conditions require prompt medical attention.

Seeking Medical Evaluation

If blurry vision persists or worsens, especially if accompanied by other concerning symptoms such as pain, redness, or flashes of light, it’s crucial to seek prompt medical evaluation from an eye care professional such as an optometrist. Optometrists are primary eye care providers who can perform comprehensive eye examinations, prescribe glasses or contact lenses, and diagnose and manage various eye conditions. They can also detect signs of systemic diseases that may manifest in the eyes.
