How does vision loss happen?
Vision loss can be the partial or complete loss of ability to see. It takes place swiftly and unexpectedly, causing utter loss of visibility or leaving you with an improper vision. The time of vision loss can vary from seconds to minutes to a few days. It can happen only in one eye or two eyes. You may be able to see clearly with one eye, but from the other, you can’t seem to see at all. Gradual vision loss, which happens in months or years, and sudden visual loss do not take too much time as they are affected severely by external factors. There are a number of causes that are responsible for partial or complete loss of vision, including ageing, migraine, injuries or any medical condition which can be treated at an Eye Hospital In Punjab.
Causes for sudden vision loss
Migraine
Many people who suffer from migraine problems sometimes show visual symptoms called migraine aura. Visual symptoms are seen in around 20-25% of people who have migraines, which causes them to see zig-zag lines, spots, or sparkles, which occasionally but not always occur with a headache that usually lasts for about an hour or less than that, while some just occur for a couple of seconds.
Keratitis
This kind of condition is mostly experienced by people who wear contact lenses that cause inflammation of the cataract. The symptoms of keratitis include blurry vision or vision loss, pain, and sensitivity to light, which are influenced by an injury or infection. It is a temporary condition that can be treated with a Cataract Surgery In Jalandhar.
Conjunctivitis
It is the inflammation of the Conjunctiva due to an infection or allergy. Conjunctivitis is frequently known as pink eye, which can cause vision loss and blurriness or difficulty in visibility, redness, and pain. The temporary infection usually heals itself, but antibiotic eye drops may help it more.
Eye strain
Looking at a screen for a long time may result in a person losing vision or things seeming blurry when they look at them. Eye strain is usually temporary, and to resolve it, all you need to do is to take some time off the screen. By following the 20-20-20 rule, one can help themselves with eye strain. The rule tells you to take time off the screen after every 20 minutes and look away into the distance 20 feet away for 20 seconds.
Corneal abrasion
Eye injury, depending on its severity, can also cause vision loss temporarily or permanently, and the treatment varies accordingly.
Causes of gradual vision loss
AMD or Age-related macular degeneration
Age-related macular degeneration is a disease that results in vision loss by impacting the central vision of a person. Many people start to experience AMD in their 50s, beginning with blurriness in the area of central vision, which can increase with time gradually or sometimes rapidly.
Glaucoma
A number of diseases cause glaucoma, which is responsible for damaging the optic nerve located at the back of the eye. A person might not know that they have glaucoma until they examine their eyes as the symptoms of it start to appear gradually. It can affect both your eyes.
Glaucoma is treated using a few methods, like eye drops, laser treatment, and surgery. Although these treatments can not fix the damage that is already done, they can stop it from going any further, as if not treated, it can cause blindness.
Diabetic Retinopathy
It is a condition that can result in blindness and loss of vision in people who have diabetes. It impacts blood vessels that are light-sensitive tissues present in the retina.
It is a good idea to have regular eye checkups for a person with diabetes, as diabetic retinopathy can happen in any diabetic person.
Prevention
Preventing vision loss is not possible completely, but there are some measures you can take by following some steps of eye care:
Rest your eyes: Never forget the 20-20-20 rule. Your eyes need to take a rest away from the screen as it is mostly the reason that even children and teenagers are wearing glasses because they are addicted to sitting in front of the screen without taking a break, which results in vision loss at such an early age.
Protect your eyes with glasses: Protecting your eyes while doing certain activities like playing sports, doing construction or doing home repair is essential in order to prevent any sort of injury that may result in vision loss.
Wear sunglasses: UVA and UVB radiations are harmful in every way, so it is better to choose the right kind of sunglasses that would protect your eyes from these radiations, lowering the chances of vision loss. There are also many exercises and lifestyle changes that you can adapt in order to maintain good vision health.
