What is blurred vision?
Blurred vision is when an object you are viewing appears unclear. It is how many people describe their vision when their eyesight is not properly corrected. Blurred vision can however be caused by many different things and if you are experiencing any abnormal vision you should immediately consult a qualified medical practitioner or eye care professional.
What causes blurred vision?
Blurry vision can be caused from several problems where the eye cannot focus properly, these include myopia, hyperpopia, presbyopia and astigmatism.
Blurred vision may result when the eye is infected, inflamed, diseased or damaged in some way, such as:
- a cataract that makes the lens within your own eye become cloudy
- age-related macular degeneration and other degenerative retinal conditions where light-detecting neurones at the back of the eye are damaged
- non-inflammatory damage to the retina in the eye due to diabetes or hypertension
- retinal detachment – a condition when the retina becomes dislodged from its support tissue
- deposits within the gel inside the eye, known as ‘floaters’.
A number of conditions that do not directly involve the eye, such as migraine or stroke can also result in blurred vision as one of the symptoms. Some medications may also lead to a temporary blurred vision symptom as a side effect.
The list of possible causes shown above is not designed to be exhaustive or help you to make a diagnosis. If you are experiencing changes to your vision or are concerned in any way about your eyes, you must seek the advice of a medical practitioner or eye care professional immediately.
Can uncorrected vision cause blurred vision?
Eyesight can change during your lifetime resulting in blurred vision because the eye can no longer focus correctly. Conditions may include:
- myopia (short sightedness) - objects are seen more clearly when they are close to the eye, while distant objects appear blurred or fuzzy
- hyperopia (long sightedness) - vision is better for distant objects than for near objects
- astigmatism – vision is blurred or distorted at all distances due to an irregularly shaped eye
- presbyopia - an age-related inability to focus sharply on close objects

What different types of contact lenses are available for common vision correction needs?
Soft lenses
Most contact lenses available today are soft lenses. They are suitable for most common vision correction needs. Soft lenses are comfortable, easy to wear and most people get used to them easily as they are supple, soft and highly flexible, contouring easily to the shape of your eye. Soft contact lenses are available as both daily disposable and as reusable lenses.
Daily disposable lenses
Daily disposable contact lenses are intended for single use only, after which you dispose of them. This enables you to benefit from the comfort, convenience and hygiene of fresh new lenses every day. Like reusable disposable contact lenses, these are also now available in exceptionally high oxygen materials such as 1•DAY ACUVUE® TruEye®
Reusable lenses
Reusable lenses are reused the following day for between one week and one month. The number of weeks will depend on the product you choose to wear. Unless specifically prescribed for sleeping in at night, they should be removed and cleaned every night. Reusable contact lenses provide exceptional long-lasting comfort and are available in materials that deliver very high oxygen levels to the eye which will keep them looking white and enable you to wear them for longer hours in the day.
Type of lens
Contact lenses for short and long sight
Spherical contact lenses correct basic vision correction needs including short-sightedness (myopia) and long-sightedness (hyperopia). 1•DAY ACUVUE® TruEye®, 1•DAY ACUVUE® MOIST®, ACUVUE® OASYS® and ACUVUE® ADVANCE® are suitable to correct these vision impairments, quickly, comfortably and easily.
Contact lenses for astigmatism
Soft contact lenses will correct astigmatism by compensating for the differences in the shape of the eye. To find out more about astigmatism, please click here.
Contact lenses for presbyopia
Bifocal or multifocal contact lenses are used to correct presbyopia which is long sightedness that occurs usually over the age of 40 when it becomes harder to see or read close up and you start to hold things further away! ACUVUE® BIFOCAL brand contact lenses can correct this, allowing you to see both near and far. Another alternative method for correcting presbyopia is called monovision, where one eye is prescribed for distance and the other eye for reading. This method can be used with any of the contact lenses suitable for correcting short or long sight or astigmatism, as required.
