Eye focusing problems and dark vision?

for a while now, ive been getting dark vision and dizzy when i stand, as if i blinked slowly. lately, maybe within the past week, ive also been having trouble focusing my eyes with no pattern as to when this shows up, neither brightness nor distance of where im looking. im wondering if this could be related? im 15, have astigmatism (i wear both contacts and glasses), and lately have also been feeling tired and stressed. what could be some possible causes of this? i believe my mother has meniere's disease, could i be showing signs of this at an early age?

This could be related to other health issues like blood pressure. Dizziness throws your vision off and disorients people which would effect your eyes. The reason I say blood pressure I know my mother experienced similar problems.

Since I had no idea about this disease, I just looked it up. It doesn't mention vision BUT it does mention dizziness. Go see your doctor asap and get yourself checked. Don't mess with your vision and don't wait for somethig else to happen or gets worse.

Meniere's Disease

What Is Meniere's Disease?
M茅ni猫re鈥檚 disease, also called idiopathicendolymphatic hydrops, is a disorder of the inner ear. Although the cause is unknown, it probably results from an abnormality in the fluids of the inner ear. M茅ni猫re鈥檚 disease is one of the most common causes of dizziness originating in the inner ear. In most cases only one ear is involved, but both ears may be affected in about 15 percent of patients. M茅ni猫re鈥檚 disease typically starts between the ages of 20 and 50 years. Men and women are affected in equal numbers.


What Are The Symptoms?
The symptoms of M茅ni猫re鈥檚 disease are episodic rotational vertigo (attacks of a spinning sensation), hearing loss, tinnitus (a roaring, buzzing, or ringing sound in the ear), and a sensation of fullness in the affected ear. Tinnitus and fullness of the ear in M茅ni猫re鈥檚 disease may come and go with changes in hearing, occur during or just before attacks, or be constant. There may also be an intermittent hearing loss early in the disease, especially in the low pitches, but a fixed hearing loss involving tones of all pitches commonly develops in time. Loud sounds may be uncomfortable and seem distorted in the affected ear. From all the M茅ni猫re鈥檚 disease鈥檚 symptoms, vertigo is usually the most troublesome. It is commonly produced by disorders of the inner ear, but may also occur in central nervous system disorders. Vertigo may last for 20 minutes to two hours or longer. During attacks, patients are usually unable to perform activities normal to their work or home life. Sleepiness may follow for several hours, and the off-balance sensation may last for days. The symptoms of M茅ni猫re鈥檚 disease may be only a minor nuisance, or can become disabling, especially if the attacks of vertigo are severe, frequent, and occur without warning.


How Is A Diagnosis Made?
The physician will take a history of the frequency, duration, severity, and character of your attacks, the duration of hearing loss or whether it has been changing, and whether you have had tinnitus or fullness in either or both ears. You may be asked whether there is history of syphilis, mumps, or other serious infections in the past, inflammations of the eye, an autoimmune disorder or allergy, or ear surgery in the past. You may be asked questions about your general health, such as whether you have diabetes, high blood pressure, high blood cholesterol, thyroid, neurologic or emotional disorders. Tests may be ordered to look for these problems in certain cases. When the history has been completed, diagnostic tests will check your hearing and balance functions. They may include:

For Hearing

An audiometric examination (hearing test) typically indicates a sensory type of hearing loss in the affected ear. Speech discrimination (the patient鈥檚 ability to distinguish between words like 鈥渟it鈥?and 鈥渇it鈥? is often diminished in the affected ear.
For Balance

An ENG (electronystagmograph) may be performed to evaluate balance function. In a darkened room, recording electrodes are placed near the eyes. Warm and cool water or air are gently introduced into each ear canal. Since the eyes and ears work in a coordination through the nervous system, measurement of eye movements can be used to test the balance system. In about 50 percent of patients, the balance function is reduced in the affected ear.
Rotational testing or balance platform, may also be performed to evaluate the balance system.
