👉 Any abnormality of the components of the eye, such as the cornea, retina, or optic nerve, can cause sudden blurred vision. Blurred vision that progresses slowly is often caused by long-term medical conditions. Sudden blur is usually caused by a single event.
- The causes of Blurry Vision are -
1. Due to Ageing👀
➤ As per the scientific community data:- Our visual field decreases by one to three degrees per decade of life. When a person reaches his 70s or 80s, he may have peripheral visual field loss of 20 to 30 degrees.
➤ Aging along with ocular pathology(especially cornea, lens, and vitreous) also causes blurring of vision.
2. Rubbing your eyes continuously👀
➤ Rubbing your eyes regularly over a long period of time can cause a thinning of the cornea(Which is called Keratoconus) and causes the cornea to lose its shape. This condition can cause blurred vision, and sometimes it cannot be completely corrected with glasses or contact lenses.
➤ Rubbing with an uncleaned hand can create infection and inflammation to the eye.
3. Eye fatigue:👀
➤ Eye strain can occur after looking and focusing on something for a long time without interruption.
➤ When it comes to focusing on an electronic device like a computer or cell phone, it is sometimes referred to as digital eye strain. Other causes include reading and driving, especially at night and in bad weather.
- "Prolong near work and sudden distant blur vision" is the complaint of school and college students day by day.
4. Refractive errors, such as near-sightedness, far-sightedness, or astigmatism
➤ The refractive error results in blurring of vision. If the patient does not use corrective power glasses or contact lens, he will suffer from severe blurring of vision which can lead him permanent vision impairment also.
➤ The Blurring signals coming from digital screen devices and the screen time will increase the risk of refractive error and can make blurring of vision permanent.
5. Cataracts:👀
- Cataract patent most commonly complains about the blurring of vision as a foggy vision or cloudy vision and the blurriness become worse over time.
6. Glaucoma:👀
➤ The rise in Intra-ocular-pressure(IOP) results in progressive optic neuropathy and visual field defect.
➤ The progressive primary open-angle glaucoma(POAG) causes vision loss gradually without pain. So the patient is unaware of it. It is most common above the age of around 40 years. From this age, everyone should check their eyes annually.
7. Migraine:👀
➤ Approximately one-third of those people with migraine also experience Visual disturbance symptoms like blurring of vision, Sensitive to light and sound.
8. Trauma or injury to the eyes:👀
➤ The most common head injury symptoms show the blurring of vision, double vision, and loss of peripheral vision.
➤ A wide variety of accidents include trauma from sharp objects, blunt force, and falls to the eye make blurring of vision and
9. Corneal and lens opacification, or scarring👀
➤ Due to natural aging or any pathological changes to the Corneal and Lens, their transparency is gradually lost for which blurring of vision, loss of visual field is experienced by the patient.
➤ It is the most common among people and if the treatment will delay, the patient will be visually impaired forever.
10. using incorrect eyeglasses👀
➤ Incorrect glass prescription and old glasses or contact lens prescription can not focus the distant light rays as well as near light rays properly at the Retina and makes a blur signal to the retina which further increases the patient refractive condition very badly.
➤ Before prescribing glass, a complete battery of orthoptist examinations should be performed such as Pseudomyopia, accommodation excess and, accommodation spasm. Because these test helps an optometrist or an ophthalmic assistant to prescribe an appropriate prescription.
11. retinopathy, such as diabetic retinopathy👀
➤ Poorly controlled blood sugar can lead to temporary swelling of the crystalline lens of the eye and result in the blurring of vision.
➤ If it will be recurrent, then the vision loss will be permanently established.
➤ Diabetic Retinopathy, Hypertensive retinopathy, and sickle cell retinopathy can damage the central retina and its periphery which leads to visual field loss.
12. Infected eyes:👀
➤ An infected eye even produces difficulties in distant vision and near vision. Moderate to severe bacterial, viral, and fungal infections can cause temporary vision loss.
➤ Corny diphtheria, Neisseria gonorrhea, Neisseria meningitides, listeria, shigela, hemophiliaus are cornea scaring bacteria.
➤ Also called pink eye, conjunctivitis is an infection of the outer wall of the eye. It is usually caused by a virus, but can also be caused by bacteria or allergies.
13. Optic neuritis:👀
➤ The inflammation of the optic disc causes loss of contrast sensitivity, problems in color identification, blurring of vision and, loss of visual field.
➤ The patient needs to treat properly unless the patient will be permanently blind.
Conditions requiring immediate assessment and treatment:
A. Detached retina:
➤ A detached retina is when your retina pulls away from the back of your eye and loses blood and nerves.
➤ When this happens, you see flashing lights and black spots followed by an area of blurry or no vision. Without emergency treatment, vision in this area can be permanently lost.
B. Stroke:
➤ Blurred or lost vision in both eyes can occur when you experience a stroke affecting the part of the brain that controls vision. A stroke affecting your eye causes blurry or lost vision in one eye.
➤ You may have other symptoms of a stroke, such as weakness on one side of your body or an inability to speak.
C. Transient ischemic attack:
➤ Transient ischemia (TIA) is a stroke of fewer than 24 hours. One of its symptoms may be blurred vision in one or both eyes.
D. Wet macular degeneration:
➤ The center of your retina is referred to as the macula. Abnormal vessels can develop, causing blood and other fluids to leak into the macula. This is called wet macular degeneration.
➤ This causes blurring and loss of vision in the central part of your visual field. Unlike dry macular degeneration, this type can start suddenly and progress quickly.
E. Angle-closure glaucoma:
➤ Closed-angle glaucoma occurs when the drainage system in the eye is blocked. In this situation, the pressure inside the eye can build up very quickly, causing redness, pain, and nausea.
➤ This is a medical emergency and requires treatment with eye drops to open the angle, decrease pressure, and decrease inflammation. In many cases, a laser procedure, known as laser iridotomy, is also required.
Blurry Vision During Morning Time:👀
A. Sleeping Face Down
B. Medication Before Bedtime
C. Eye allergies
D. Fuch's Corneal Dystrophy
E. Drinking Alcohol at bedtime
F. Sleeping with contact lense
G. Glands present in the eye
Treatment of blurred vision:🙋
➤ The treatment of blurry vision depends entirely on what is causing the blurring. Refractive errors like hyperopia, myopia, and astigmatism can be corrected by using eyeglasses or contact lenses, the latter being a more comfortable option, but it's important to keep your contacts clean.
VISIONspot MSG:👉
➤ Blurred vision refers to a lack of clarity of vision that results in an inability to see fine details.
➤ Now and days people are getting aware of eye health and care for it but it is not sufficient.
➤ In our busy schedule, We should not only care for outlook but also prepare for a better sight for a better world.
