Blurred Vision

Is multi-faceted; Here are just some of the reasons your vision is blurry:

Front of the eye

Your cornea (the clear layer that covers the front of your eye), or the shape of your eye itself means you need to have your vision corrected using lenses.

Corneal abrasions – Have you scratched your eyes or had an eye injury recently? Perhaps you have got something in your eye? Scratches as a result of getting grit in the eye, eye rubbing, chemical irritation etc. can cause abrasions. These abrasions can heal quickly (24 to 72hrs), but can develop into infections.

If you think that you have dust or dirt in your eye, try rinsing your eye for several minutes using clean water. Do not rub your eye. If you are wearing contact lenses, take them out. If you don’t have access to water, pull your upper eyelid outward and downward over your lower eyelid. This simple maneuver may allow your natural flow of tears to flush the debris away. If these strategies do not help, or if you think your eye has been scratched, book an emergency appointment with us.

Your optometrist may prescribe antibiotics or other medications to treat infection and damage to the cornea. He may also recommend you take pain relief. Keep your contact lenses in their case until you are advised you can wear them again. It’s very likely that you will need a follow up appointment or a teleconsultation.

Corneal opacifications – An infection, often the result of an injury causes your cornea to become cloudy. This clouding (produced by scars), stops the light passing through to the structures that help us to see and can interfere with your vision. Your Independent prescribing Optometrist could advise you to take eye drops including anti biotics, steroids or suggest phototherapeutic keratectomy (PTK), if scarring is close to the corneal surface. In more severe cases you may need to consider a corneal transplant.

Dry eye syndromes including blepharitis – Often age related and affecting those with underlying health conditions can cause your vision to be blurred. Treatment relies on the underlying cause of the dry eyes and can include drops, Blephex treatments and procedures to block your tear ducts amongst other things.

We check these conditions out during the anterior part of your eye examination and may direct you to the appropriate eye care package for your eyes should you need additional help. Those on our gold package will receive Slit lamp bio microscopy as standard.

Structures within the eye

Lens Cataracts, changes to the lens of the eye
Retina Age related macular degeneration, Diabetic retinopathy
Vitreous Posterior vitreous detachment (PVD)
Optic Disc Glaucoma, Optic neuritis

Ophthalmoscopy (where the inside of your eye is viewed to rule out a number of conditions), is often conducted on a dilated pupil at McShaw Optometrists, so we get a really good wide and stable view. It takes longer but it’s worth it. The entire retina is a fundamental part of your eyes’ architecture and is the only part of the central nervous system visible from outside of your body. This procedure is carried out no matter which package you choose. Further examinations and images are conducted, depending on the package you choose to consider the structures in greater detail and so pick up conditions sooner, so aiding the preservation of your vision.

Other causes


Low blood sugars for those with diabetes

Stroke, if accompanied by face drooping, loss of balance, slurred speech. Loss of strength down one side of your body. Seek medical help immediately.

As you can see blurred vision has a number of causes and a complete eye examination enables your optometrist to identify the sources and so correct your vision and treat the underlying causes.

Asking questions and getting a good history, along with the examination ruling out or confirming certain features, allows your optometrist to identify or suggest systemic conditions. We can refer you to health specialists and your G.P. when it’s appropriate so you are always in good hands.

Book an examination: our most popular package: The advanced care (where, depending on your symptoms we tailor-make your examination to your highest risks). Whatever package you choose, you will have our expertise, in-depth anaylsis and a wide range of solutions.
