PT: Binocular Vision Disorder (BVD) Pride Flag

ID: a pale olive with two overlapping triangles. On the left is a black triangle, pointing towards the right. It's overlapped by a lighter gray triangle, coming from the right and pointing towars the left. In center are overlapping gray polygons. The lighter ones are semi-transparent, it makes the darker shapes beneath show through. /end ID

Grey is frequently associated with visual disabilities (link), and green on the disability pride flag represents sensory disabilities. The triangles overlapping = double vision reference.

Binocular Vision Disorder (BVD): dysfunction of binocular vision (put together by the brain with input from both eyes). BVD can cause blurred or double vision, photophobia, trouble focusing on small, faint, far away or up close objects and nyctalopia.

It often affects reading: needing to reread, skipping lines, losing track, trouble with long without punctuation. The eyes and brain have to overcompensate, resulting in head and neck tension, which can cause eye pain/strain and headaches.

Conflicting infos beteween sight and nonvisual sensory canals that sight supports can cause disorientation, vertigo, dizziness, motion sickness, trouble walking straight or frequent collisions, sensory overload, anxiety in crowds or large places.

BVD is pretty comon, though frequently missed, since it's vastly unknown. If you have ADHD and/or double vision when you zoom out, u should prob look into it.

The Eye Symptoms of Physostigma and Ruta

Materia Medica Tip – 36

Today’s materia medica tip revolves around the eye symptoms of two important remedies, namely, Physostigma and Ruta. Whereas many of us use physostigma and Ruta for various eye complaints (including some non verifed claims of refractory errors corrections), we might not be exploring the in depth use of these remedies.

The classical symptoms of Physostima are described in…

These Days we spent most of our time in front of the Screen of Computer, TV, Cellphones…

Nearly 50-90%  of the users are suffering from Computer Eye Strain.. It is Becoming one of the important job related problem faced Nowadays….

It is Nearly impossible to avoid this ‘Idiot Box’ but with few precaution we can protect our eyes

Digital Eye Strain and Computer Vision Syndrome can affect your vision Badly and Affect your efficiency at workplace.

  So, here are some tips to protect your eyes, if you spend your most of the time in front of Computer Screen:

  Follow 20-20-20 Rule:

Important cause of computer eye strain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds. Some eye doctors call this the “20-20-20 rule.” Looking far away relaxes the focusing muscle inside the eye to reduce fatigue.

  Have Regular Eye Checkups:

Having a routine comprehensive eye exam is the most important thing you can do to prevent or treat computer vision problems.According to the National Institute of Occupational Safety and Health (NIOSH), computer users should have an eye exam before they start working on a computer and once a year thereafter.

During your exam, be sure to tell your eye doctor how often you use a computer at work and at home. Measure how far your eyes are from your screen when you sit at your computer, and bring this measurement to your exam so your eye doctor can test your eyes at that specific working distance.

  Take Care of Lighting:

Eye strain often is caused by excessively bright light either from outdoor sunlight coming in through a window or from harsh interior lighting. When you use a computer, your ambient lighting should be about half as bright as that typically found in most offices.

Eliminate exterior light by closing drapes, shades or blinds. Reduce interior lighting by using fewer light bulbs or fluorescent tubes, or use lower intensity bulbs and tubes. If possible, position your computer monitor or screen so windows are to the side, instead of in front or behind it.

Try reducing the number of fluorescent tubes installed above your computer workspace if you are bothered by overhead lighting.

  Take Care of Glare:

Glare on walls and finished surfaces, as well as reflections on your computer screen also can cause computer eye strain. Consider installing an anti-glare screen on your monitor and, if possible, paint bright white walls a darker color with a matte finish.

Again, cover the windows. When outside light cannot be reduced, consider using a computer hood.

If you wear glasses, purchase lenses with anti-reflective (AR) coating. AR coating reduces glare by minimizing the amount of light reflecting off the front and back surfaces of your eyeglass lenses.

  Upgrade your display:

If you have not already done so, replace your old tube-style monitor (called a cathode ray tube or CRT) with a flat-panel liquid crystal display (LCD), like those on laptop computers.

LCD screens are easier on the eyes and usually have an anti-reflective surface. Old-fashioned CRT screens can cause a noticeable “flicker” of images, which is a major cause of computer eye strain. Even if this flicker is imperceptible, it still can contribute to eye strain and fatigue during computer work.

  Adjust your PC according to your Eyes:

Adjusting the display settings of your computer can help reduce eye strain and fatigue. Generally, these adjustments are beneficial:

Brightness. Adjust the brightness of the display so it’s approximately the same as the brightness of your surrounding workstation. As a test, look at the white background of this Web page. If it looks like a light source, it’s too bright. If it seems dull and gray, it may be too dark.

Text size and contrast. Adjust the text size and contrast for comfort, especially when reading or composing long documents. Usually, black print on a white background is the best combination for comfort.

Color temperature. This is a technical term used to describe the spectrum of visible light emitted by a color display. Blue light is short-wavelength visible light that is associated with more eye strain than longer wavelength hues, such as orange and red. Reducing the color temperature of your display lowers the amount of blue light emitted by a color display for better long-term viewing comfort.

  Blink More Frequently while at work:

Blinking is very important when working at a computer; blinking moistens your eyes to prevent dryness and irritation.

When working at a computer, people blink less frequently — about one-third as often as they normally do — and many blinks performed during computer work are only partial lid closures, according to studies.

Tears coating the eye evaporate more rapidly during long non-blinking phases and this can cause dry eyes. Also, the air in many office environments is dry, which can increase how quickly your tears evaporate, placing you at greater risk for dry eye problems.

  Take a Break:

To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer work day.Many workers take only two 15-minute breaks from their computer throughout their work day. 

According to a recent NIOSH study, discomfort and eye strain were significantly reduced when computer workers took four additional five-minute “mini-breaks” throughout their work day.

And these supplementary breaks did not reduce the workers’ productivity. Data entry speed was significantly faster as a result of the extra breaks, so work output was maintained even though the workers had 20 extra minutes of break time each day.

  Take a look at your Workstation:

If you need to look back and forth between a printed page and your computer screen, this can cause eye strain. Place written pages on a copy stand adjacent to the monitor.

Light the copy stand properly. You may want to use a desk lamp, but make sure it doesn’t shine into your eyes or onto your computer screen.

Improper posture during computer work also contributes to computer vision syndrome. Adjust your workstation and chair to the correct height.

Purchase ergonomic furniture to enable you to position your computer screen 20 to 24 inches from your eyes. The center of your screen should be about 10 to 15 degrees below your eyes for comfortable positioning of your head and neck.

  Use Computer Eyewear:

For the greatest comfort at your computer, you might benefit from having your eye care professional modify your eyeglasses prescription to create customized computer glasses. This is especially true if you normally wear contact lenses, which may become dry and uncomfortable during sustained computer work.
