Iodine In The Eye
Circulation: The aqueous functions as the clear "blood" of the front of the eye. It is produced in a ring gland behind the outer edge of the iris called the ciliary body. The fluid bathes the eye interior and supplies oxygen and nutrients to the lens and the inside of the cornea, carrying away waste products and carbon dioxide. Dysfunction of the drains can lead to glaucoma. ...Read more

Not standardized: First you have to define the size of a pixel since this varies with the device because a pixel can be of different widths. Photoreceptor packing is analogous to pixels and the resolution depends upon that packing. Once you have decided which size pixels you are using for this, then you can look up photoreceptor size and compare them. ...Read more
Risky: This is the area of central vision which you use to read and recognize fine detail. A burst vessel in this area can block the view by covering this area with blood or can be a vessel feeding this area and bursting disturbs the blood supply so the area can cease to function well. It is therefore dangerous and needs immediate attention by an ophthalmologist or retinal specialist. ...Read moreSee 2 more doctor answers
The retina: The retina is the light sensitive structure in the eye. One may think of it as the film in a camera, or the light sensitive chip in a digital camera. Each rod or cone like a pixel. The rods "see" black and white and are very light sensitive (think: night vision), while the cones "see" color, but need more light to function. The fovea (are of central vision) is about 90% cones. ...Read moreSee 1 more doctor answer
Dryness: Likely your eyes are dry if outdoors in high altitude because of low humidity. The redness is due to the irritation provoked by the low humidity environment.

Usually not: Sawdust commonly enters the eyes of those working with wood and near those working with wood. With each blink, most exits. Most saw dust is inert and will not be toxic in itself. The major harm would be for instance if someone is drilling in wood, creating sawdust of course, but hitting a piece of metal which flies into the eye. ...Read moreSee 1 more doctor answer
Aqueous humor: This is a clear fluid, derived from blood serum, which contains some nutrients, oxygen and which bathes and provides for the health of the interior components of the front of the eye. It also maintains the normal pressure so that proper focusing is possible. It is produced continuously and an equal amount drains continuously. ...Read moreSee 1 more doctor answer

Slight underactive thyroid. On meds but doc sd to also increase iodine intake. I'm putting iodized salt on everything. Darker circles under eyes help.
Iodine intake: Unless you live in a very remote part of the world, or unless you consume a very unusual diet, there is probably already plenty of iodine in your diet, and more will not help your hypothyroidism. If your thyroid is failing, you need to take levothyroxine in an appropriate dose, and that will take care of the thyroid problem. ...Read more

Crystalline lens: Your eye is a complicated organ system. Inside the front of the eye there is a fluid chamber between the cornea and the colored part of your eye, called the iris. In the center of the iris there is an opening called the pupil and behind that another chamber between the iris and the crystalline lens. The lens is a disc shaped living tissue composed of regularly arranged collagen with a capsule. ...Read moreSee 2 more doctor answers

Most of them are benign, but you want to follow the recommendation of an ophthalmologist as sometimes people can have choroidal melanoma - a tumor in the eye.

Often w/o Symptoms: This condition is classically a multi organ inflammatory condition. Specific to the eye, inflammation occurs in the front (iritis) and back (uveitis) of the eye, optic nerve, and lacrimal gland tissue as well. The exact cause of this condition is not known, but it's considerable, often without symptoms, and profound in certain patients. Therefore, I would highly recommend that every patient with sarcoidosis be examined by an amount just regularly. Please take care of this. ...Read moreSee 1 more doctor answer
