Lighting Your Workspace and Home When You Have Low Vision – WebMD

July 6, 2022 by No Comments

What is low vision? This vague-sounding condition, which is sometimes called vision loss or visual impairment, is a permanent, life-changing diagnosis. It’s not the same as blindness — which occurs when you lose most or all of your vision — and it’s also different than simple nearsightedness or farsightedness, which both affect how clearly you see objects. 

Low vision refers to an irreversible type of vision loss that might be caused by one of many different eye conditions or diseases. Understand what a diagnosis of low vision means and learn about lighting for low vision at home and work.

What Is Low Vision?

Low vision might stem from an eye condition like macular degeneration, or it might be the result of a broader issue like diabetes. You can’t fix this type of vision loss by wearing glasses or getting surgery, and there are no medications you can take to treat it. 

Fortunately, there are many proven ways to address low vision to help you live a fuller, more productive life. You’ll work with your doctor to consider options like vision aids, glasses that magnify text, and small binoculars that can help you see things better when you’re far away from them.

What Causes Low Vision?

To know whether you truly have low vision — which is permanent, partial vision loss — or another condition that affects how well you see, you’ll have to visit an ophthalmologist, which is a medical doctor who has special training in detecting eye-related issues. 

The following conditions are common causes of low vision:

  • Macular degeneration: This condition mostly affects older people, and it isn’t reversible — but it’s not common to go completely blind if you have macular degeneration. You might not notice any symptoms at first, but over time, your vision will become blurry, and you might have trouble recognizing people.
  • Glaucoma: Like macular degeneration, glaucoma usually affects older people, but younger people can get it, too. It’s a result of high eye pressure damaging your optic nerve. If you have vision loss from glaucoma, you can’t get it back — but the good news is that there are treatments for glaucoma that slow down the damage.
  • Diabetes: Diabetes is, first and foremost, a problem with how your body processes your blood sugar — but when this condition is untreated, the damage can spiral out of control and affect other parts of your body. When your blood sugar remains high for too long, this can lead to glaucoma, cataracts, and swelling in the lens of your eyes. Some of these diabetes-related eye problems are reversible, but some are not.

Are Nearsightedness and Farsightedness Types of Low Vision?

No, these conditions are different: Nearsightedness (myopia) and farsightedness (hyperopia) are both treatable conditions that interfere with the clarity of your vision. While you should seek out treatment with eyeglasses, contacts, or laser surgery, these conditions are not usually serious and won’t cause long-term health problems. 

Symptoms of nearsightedness include blurriness when you look at things that are far away, headaches, and worsening night vision. Many children, teens, and young adults experience symptoms early in life, and many older adults develop the condition as they age.
