Visual impairment, also known as vision impairment or vision loss, is a decreased ability to see to a degree that causes problems not fixable by usual means, such as glasses.[1][2] Some also include those who have a decreased ability to see because they do not have access to glasses or contact lenses.[1] Visual impairment is often defined as a best corrected visual acuity of worse than either 20/40 or 20/60.[7] The term blindness is used for complete or nearly complete vision loss.[7] Visual impairment may cause difficulties with normal daily activities such as reading and walking without adaptive training and equipment.[2]
The most common causes of visual impairment globally are uncorrected refractive errors (43%), cataracts (33%), and glaucoma (2%).[5] Refractive errors include near-sightedness, far-sightedness, presbyopia, and astigmatism.[5] Cataracts are the most common cause of blindness.[5] Other disorders that may cause visual problems include age-related macular degeneration, diabetic retinopathy, corneal clouding, childhood blindness, and a number of infections.[8] Visual impairment can also be caused by problems in the brain due to stroke, premature birth, or trauma, among others.[9] These cases are known as cortical visual impairment.[9] Screening for vision problems in children may improve future vision and educational achievement.[10] Screening adults without symptoms is of uncertain benefit.[11] Diagnosis is by an eye exam.[2]
The World Health Organization (WHO) estimates that 80% of visual impairment is either preventable or curable with treatment.[5] This includes cataracts, the infections river blindness and trachoma, glaucoma, diabetic retinopathy, uncorrected refractive errors, and some cases of childhood blindness.[12] Many people with significant visual impairment benefit from vision rehabilitation, changes in their environment, and assistive devices.[2]
As of 2015 there were 940 million people with some degree of vision loss.[6] 246 million had low vision and 39 million were blind.[5] The majority of people with poor vision are in the developing world and are over the age of 50 years.[5] Rates of visual impairment have decreased since the 1990s.[5] Visual impairments have considerable economic costs both directly due to the cost of treatment and indirectly due to decreased ability to work.[13]

My eyesight has gotten really bad over the last 2 years. I have always been a casual wearing glasses. Within a space of about 2 years i have been wearing them permanent.
I did put on 25kg from 86kg-110kg. Since 2019. And i was diagnosed with diabetes mid last year (around the time my visions gotten even worse)
They say loosing weight can help blurry vision. Im not sure what else i can try 😢
I Pray in the MIGHTY NAME OF JESUS CHRIST OF NAZARETH THAT YOU GET SAVED IN JESUS CHRIST NAME. Any demonic possessions or health issues causing his eyes to go bad I Pray it is removed in the MIGHTY NAME OF JESUS CHRIST. Free him and his eye sight in the name of the Father LET HIM SEE. IN THE MIGHTY NAME OF JESUS CHRIST YESHUA HAMASHIACH RUACH HA-KODESH YHWH AMEN 🙏🏽🙏🏽❤️🔥❤️🔥
@@onlyenzoYT amen ❤️. thankyou so much. actually means the world to me growing up a catholic/christian. i admit though i haven’t been the best with my religion. i haven fallen in and out of following it for a while..i have sinned in the past almost always unitentionally. 😥
@@matt17389you need to change your lifestyle. Stop eating sugar this includes fruits and honey, stop eating gluten, reduce seed oil consumption and lastly start fasting one meal a day or two meals (there needs to be a 9hr gap between both meals). My eyesight was bad but it’s significantly better I can’t see clearer your body is designed to health itself if you stop abusing it
i need surgery what is your opinion on that
Shingles should be on list , as is how I'm going blind
Wishing you quick recovery
May the Lord have mercy upon the blind in Jesus name Amen.

I once experienced double vision out there.

Folks please go and see an Optemetrist in order to see the capacity thing eyes in Ghana.
Blindness can be cured: work at home in 3 areas. Primary vision(occipital lobe), secondary vision(phisical eyes) and terciary vsion(third vision). It works.

Whenever I’m sitting for a while on the ground or just laying on my bed, whenever I stand up my vision goes all black for like 2 seconds
I'm sorry to hear you're dealing with a chalazion, Shreya. Applying warm compresses several times a day and maintaining good eyelid hygiene can help reduce the swelling and discomfort. If the pain persists, please consult a healthcare professional for further advice. ❤️
My eyelids are shaking some times can anyone explain this 🤧
Twitches in the eyelids are common I believe
So is it rare or not much normal to being born blind
U sound like a mom
Eurgh.
