Are Ther Glasse To Block Peripheral Vision
Maybe so: Computer programmers have needs that are different from other computer users. Age and need for glasses also play important roles. The stronger the prescription need, the more peripheral distortion exists. There are several glasses that come either with "blinders" or wrap-around lenses. Your optometrist or optician can likely build or modify a pair of glasses to accomplish your goal. ...Read more
When you look at someone's face, you can still see their hand, even though you are not looking directly at it. When you are walking through a doorway, you are not looking at the sides, or looking directly at the threshold, but you see it through your peripheral vision. Anything outside of your direct focus spot, is considered peripheral. Which can be measured ...Read more
My peripheral vision is better when I wear glasses instead of monovision contacts. Why would that be?
Monocular vision: The convenience of being fitted in monofocal contacts is to lessen need for glasses, at the compromise of reduced stereopsis (binocular vision). However I find improvement in peripheral vision when wearing contacts for optimum distance (binocular) vision, versus glasses. Each contact lens individual determines whether the reduction of stereopsis is satisfactory for their daily functions. ...Read more
My eyes always feel fatigued. On a computer, without glasses (-3.00) my central vision is blurry, but I notice my peripheral vision still looks clear.
Early warning: Central vision is for fine detail - reading, face recognition, etc. Peripheral vision, of low acuity, is sensitive to motion and serves to provide early warning of threats from the sides and also provides orientation to the major features of the visual space. With no peripheral vision (called tunnel vision) you cannot drive, or easily walk around, etc. ...Read more
Retina-optic nerve: Peripheral vision loss may be a retinal detachment, retinitis pigmentosa, rare drug toxicities, immune retinopathy, retinal infection, and glaucomatous optic neuropathy. In the brain migraine, and certain types of stroke can cause a loss of peripheral vision. Transient obscurations of vision may be low blood pressure. An eye examination with dilation should identify the cause. ...Read more
Migraine??: The big issue is whether it is a transient or permanent problem. Regardless, a full exam with visual field testing should help you sort out the possible cause. Migraine is most common transient type. In elderly patients you also have to assess for insufficient ocular blood flow (amarosis). ...Read more
Many possibilities: Many things can cause loss of peripheral (side) vision: glaucoma is the most likely. Ocular pressure rise causes vascular and optic nerve damage. Another is a tumor or aneurysm near the pituitary gland, compressing the nerves from the eye as they first join and then re-divide on the way to the back of the brain. Oculo-vascular occlusions can do the same although most often this is only in one eye. ...Read more
Shaking of retina: The retina only has nerves of vision and if something shakes it, you will notice a light streak. This can happen occasionally spontaneously. And also in relationship to the aging of the vitreous within the eye. If the light streaks happen one after another even with the eyes shut, then you should have an evaluation to rule out more serious conditions. ...Read more
Mult reasons: Either: 1. They don't cover your eyes completely, or. 2. The refraction isn't completely around the edge (doubt). ...Read more

Peripheral vision: Auras are visual manifestations of neurological symptoms. Flashing lights are one type of aura people report seeing, and these auras often appear in either eye. Migraines are a common cause of visual disturbances, such as flashing lights, but these uncomfortable visual symptoms can be the result of other physiological conditions as well. Anxiety, retinal disease, htn, and seizures may be an issue. ...Read more
Flashes: A bright light in your peripheral field can signify traction (pulling) on the mid-peripheral or peripheral retina. These can be warning signs of an impending or evolving retinal tear/break. Symptoms such as these are best evaluated with a dilated retinal exam. Please see your provider for evaluation. ...Read more
Few causes: Htn, optic nerve inflammation called neuritis, including drug induced op. Neuritis-multiple scelerosis, glaucoma or intraocular HTN with HTN inside eyeball, migraines, inflamm/detachment of retina which is the inner most of the 3 layers of eyball, etc. You need to get examined by eye dr. Asap to get ruled out of any of the above including space occupying lesions of brain, like mass with imaging scans. ...Read more
I have 20/30 vision looking straight at the chart. But how do I test the sharpness of my peripheral vision?
How accurate are DMV peripheral vision tests when you have glaucoma. Could test show more loss than what there really is.
Meets standards: DMV tests are not designed to detect or monitor disease. They have a standard peripheral signal that you need to detect to determine the width of peripheral vision only. If your glaucoma has not progressed to the point of affecting peripheral vision, then you should be able to easily pass that test. ...Read more
A half hour ago a light started flickering in my peripheral vision and won't stop. It's like the light after someone takes your picture?
? ocular migraine: This could be an ocular migraine episode caused by small vessel spasm but it should subside. There is usually no associated headache. However if the flickering lights persist and especially if you see new onset of spots in visual field or blurring, you should be examined by an ophthalmologist to rule out retinal tears or vessel leaks. ...Read more
Why do I get this white dot that appears for a second? It happens all day, it's just 1 dot that appears in my peripheral vision, is it from trauma?
White dot: White dots are not a typical finding from eye trauma-- this could be a partially opaque floater or a retinal tear-- seek care from your local eye doctor... ...Read more
Lattice reviewed 2 days ago- no vitreoretinal etiology found. Last night I noticed flashes in peripheral vision during (not after) hard cough. Normal?
Depends: Lattice can be a site of weakness with retinal jiggling causing the light flashes. If it only happens when you cough, and not in between and you see no new floaters and the vision remains good, then you can wait it out. If the flashing is continuous or the other factors appear, then have your ophthalmologist (you are not of course seeing an optometrist for this-right?), check it out again. ...Read more
