What is wrong with a short - sighted eye and how can it be compensated?
A short-sighted eye, or myopic eye, occurs when the eyeball is too long or the cornea is too curved, causing light rays to focus in front of the retina rather than directly on it. This results in blurry vision for distant objects. Compensation can be achieved using concave lenses in glasses or contact lenses, which help to diverge light rays before they enter the eye, allowing for proper focus on the retina. In some cases, refractive surgery, like LASIK, may also be an option to correct myopia.
Is optic nerve coloboma inherited?
Optic nerve coloboma can have a genetic component, but it is not always inherited in a predictable manner. It may occur sporadically due to a developmental error during embryonic formation, or it can be associated with genetic syndromes or inherited in families. If there is a familial pattern, it may involve mutations in specific genes. Genetic counseling is recommended for those with a family history of coloboma.
"6 by 6 eyesight," commonly referred to as 20/20 vision in the United States, indicates normal visual acuity. It means that a person can see at 6 meters what a person with normal vision can see at that distance. Essentially, it is a standard measure of clarity and sharpness of vision, where lower numbers indicate better vision. In some countries, this measurement is used to assess visual health and determine the need for corrective lenses.
The bright lighted triangle you’re seeing could be a visual phenomenon known as a phosphen, which can occur due to various reasons, including retinal issues, migraines, or even pressure on the eye. Since this has persisted for over a month and is affecting your vision, it’s important to consult an eye care professional promptly for a thorough examination to rule out any serious conditions. Don’t delay in seeking medical advice to ensure your eye health is properly assessed.
Will allergy tablets cause double vision?
Allergy tablets, particularly those containing antihistamines, can cause side effects such as drowsiness, dry mouth, and blurred vision in some individuals. While double vision is not a common side effect, it can occur in rare cases, especially if the medication affects muscle control or if the individual has an underlying condition that is exacerbated by the medication. If you experience double vision after taking allergy tablets, it's advisable to consult a healthcare professional for further evaluation.
What is the opposite condition of glaucoma?
The opposite condition of glaucoma can be considered as a state of normal intraocular pressure (IOP) and healthy optic nerve function, often referred to as "normal-tension" or "low-tension" glaucoma in a broader context. However, in contrast to glaucoma, which involves increased IOP and potential optic nerve damage, conditions like hypotony may represent a state of abnormally low IOP. In essence, while glaucoma is characterized by elevated pressure leading to vision loss, its opposite would be a healthy eye with stable pressure and no damage.
Usually means that the magnetron tube that creates the microwave is burned out. I am an EE and when this happens to a microwave I buy a new microwave rather than trying to replace the tube. Fooling with the tube and shielding can be dangerous.

What is the normal field of vision of humans?

What are small red painless dots under the surface of the skin?
These sound like petechiae, which are hemorrhages of tiny capillaries under the skin. You can sometimes get them on your neck from coughing hard or vomiting forcefully or sometimes they will appear on your arm after having your blood drawn where the tourniquet was placed. They are usually harmless, however, if you are showing signs of illness and the petechiae show up for no reason, it may be a sign of something more serious, so it is always best to check with your physician.
There is a small firm lump under my skin at the base of my penis?
A small firm lump under your skin at the base of your penis could be a cyst, but this should be confirmed with a doctor.
ANSWER: Most likely lymph glands... If you had an abscessed tooth or severe acne/boil on one side of your lower face, the "poisons" would have drained into the anterior [front] cervical [neck] chain [they are grouped like a chain]. Lymph nodes [glands] grow to filter out toxins/poison in the lymphatic system, which is essentially the third 'circulatory' system of the body. If an enfection in located in one area of the body lymph nodes grow in direct relationship to the amount of toxin/poison in that area... Most nodes are deep within the body and cannot be felt. If the person affected has a severe viral infection then the nodes under the jaw can swell [grow]... If a child has an ear infection often he/she will develop swollen nodes behind the ear at the base of the skull... HOWEVER, if a person finds enlarging nodes under the jaw AND/or under the arms, the inside of the elbows, in the groin areas, then a physician needs to be consulted as this could mean other, possibly more serious conditions... Hope this helps!
Why do grasshoppers have five eyes?
Many grasshoppers have five eyes as a defense mechanism. This allows them to see farther and wider, allowing them to evade predators.
How soon should you start steroid treatment for optic neuritis in someone with MS?
This is an interesting question. Many doctors believe that corticosteroids can positively impact MS and can cause reductions of nerve swelling in a shorter timeframe than without. But recent studies have shown that there is very little effect on optic nerve recovery time when using corticosteroids than without.
Optic neuritis, whether caused by MS or not, will right itself within a few weeks to a few months. It should be completely cleared in 6 months for most people. There is little need to help it along.
