    Low Vision and Blindness Aids for People with Vision Loss from Glaucoma

    It can be devastating. You’ve gone to your eye doctor because you notice you can’t see as well as you used to. You tried numerous treatments for your glaucoma, but your vision only got worse, and now your eye doctor tells you that your vision loss is permanent and irreversible. This news may take some getting used to, but your life is not over.

    A Guide to Glaucoma (Part 4) Care Glaucoma Your ability to adapt to your vision loss and change the way you use your vision can make a difference in your quality of life. Accepting your vision loss is an important first step.

    It is important to know that you are not alone. No matter how much or how little vision you have, there are tools you can use to maintain your quality of life. More than one-third (37%) of people with vision loss have mild vision impairment, meaning they have low vision, but they can still perform many activities with low vision aids. Even if you’ve lost your vision completely, you can still find new ways to do the things you want and need to do each day.

    There are many low vision and blindness aids for people with glaucoma that can help you maintain your lifestyle and continue to do all the things you used to—independently.

    How Glaucoma Affects Your Vision / Vision Loss from Glaucoma

    Glaucoma can affect your vision in many ways. Glaucoma shrinks your overall vision so that you lose your peripheral (side) vision, it reduces your ability to adapt from light to dark and dark to light (for example coming out of a movie theater at daytime), it makes you more light-sensitive (especially to glare) and it decreases your ability to see contrasts.

    Tunnel Vision or Reduced Peripheral Vision

    Glaucoma reduces the overall area you can see. People who lose their vision due to glaucoma often report seeing tunnel vision. It is described as looking at the world through a straw or a pinhole. You may not be able to see what is directly below, above or around you on the sides. People with glaucoma can often still see small details, but they lose the ability to see the entire picture.

    A Guide to Glaucoma (Part 4) Care Glaucoma For people with glaucoma-related vision loss, bigger does not necessarily mean better. People with tunnel vision often have trouble with high levels of magnification because of their lack of side vision and decreased field of view (the amount you can see at one time). This type of vision loss does not benefit from magnifier devices that enlarge or make things bigger. Typically as magnification increases, your field of view decreases and the stability of your image (its shakiness) also increase. This is why people with glaucoma-related vision loss have a hard time with too much magnification; it makes your reduced peripheral vision worse.

    If you have glaucoma you need the opposite of magnification; you need minimization (minification), or making the image smaller to increase your field of view (so you can see more at one time). Minimization takes what you can no longer see on the sides and puts those images into your remaining central vision by reducing or shrinking what you see to fit your remaining visual field. Minimizing lets you see more information in a smaller area.

    Contrast, Glare, and Lighting

    People with glaucoma often have trouble with lighting, contrast (seeing different shades of the same color) and glare. Poor lighting makes seeing difficult. Having too much light (sunlight, bright stores), too little light (dimly lit restaurants), or extreme changes in lighting makes it hard for people with vision loss from glaucoma to see clearly.

    Glare and Contrast

    A Guide to Glaucoma (Part 4) Care Glaucoma Glare, caused by bright lights (sun or fluorescent lighting) reduces your ability to see contrast. Glare is the excess light that comes into your eyes (from above or the sides of your vision) away from the area you are focusing on. This extra light makes it harder to see what you are looking at. Having too much light causes glare and can be reduced by wearing hats outdoors or glasses with special lenses.

    Using sunglasses with tinted lenses (or contrast-enhancing filters) can help reduce the effects of glare. You may try a few different colored lenses before you find the ones that work best for you. To reduce glare from fluorescent lighting try brown, yellow or amber lenses. To reduce glare from too much sunlight use brown lenses.

    It is important to know that not all sunglasses are helpful. Lenses that are too dark can make it harder to see what you are focusing on by dimming your vision while letting in excess light from above and on the sides. Wraparound glasses that block light coming in from above and the sides are best for glaucoma.

    When working with computers or electronic devices, use higher contrast settings to help you reduce glare and help you see better. There are also special modes, screens and hoods to help reduce glare. Other simple ways to improve the way you see include covering surfaces that reflect light and cause glare, closing curtains and changing your position so that you have less excess light.

    Low Level Lighting and “Dim” Vision

    Having too little light reduces your ability to see. Low lights cause “dim” vision where you have to strain your eyes to see clearly. Prevent low lighting effects on your vision by making sure there is enough ambient lighting in dimly lit rooms and by using task lighting. When outside on cloudy, overcast days, you can also try amber or yellow lens glasses to help you see better.

    Drastic Changes in Lighting

    People with glaucoma have a hard time adjusting their eyes to changes in lighting. Walking into a dark room or out of one into a bright area can temporarily stun the eyes so that you see less. This can be especially dangerous when walking or driving in areas that are light and dark (bridges, tunnels, shady areas). It can make it harder for you to see signs, steps, curbs or changes in terrain. If you have glaucoma, it takes longer for your eyes to adjust to extreme changes in lighting. Take a few extra moments when there is a drastic change in light to let your eyes adjust. You may also consider using a white cane if your low vision affects your mobility.

    Low Vision Aids for People with Glaucoma

    If you have vision loss, then the sooner you start to use low vision aids the better to help you adjust and to learn new ways to maintain your “normal” lifestyle/activities. Familiarity with low vision aids can also help should your vision loss progressively get worse.

    A Guide to Glaucoma (Part 4) Care Glaucoma The good news is that there are many different high and low tech products to specifically help vision loss from glaucoma. Here are some products you should consider using right away if vision loss from glaucoma has impaired your quality of life.

    Non-electronic Low Tech Low Vision Aids for People with Glaucoma

    Not all low vision aids are highly technical or electronic. Some are quite basic, but they can still greatly improve your quality of life. Here is a list of low tech, low vision aids you can use if you have vision loss from glaucoma:

    • Increased room lighting and task lighting are the simplest ways to help you to see better if you have glaucoma. Adding desk and reading lamps, as well as goose-neck lamps, can make the difference when performing tasks that require you to see up close. Making sure your environment is well-lit will help you see better overall.
    • Filters/colored lenses and glasses reduce glare and help increase contrast.
    • Sectoral prisms can increase your field of view, allowing you to see more at once.
    • Reverse telescopes reduce what you are looking at (like holding binoculars backward) so that you can see more at once. When minimizing what you see, consider your overall ability to see small details (like fine print) because these devices reduce the image of what you are looking at.
    • High minus lenses/full field microscopes (similar to reverse telescopes), like strong reading glasses, help you see more within your reduced field of view.
    • Hand-held Telescopes are held up to one eye to see objects in the distance. These telescopes are helpful for distance viewing in a classroom, at movie theaters, in lectures, for plays or even sporting events.
    • Spectacle-mounted telescopes are similar to hand-held telescopes, except they can be used for one or both eyes and are hands-free. They can fit over your glasses or be worn like glasses. They also help you view objects that are far away.
    • White canes help you to look ahead towards your destination when walking, while at the same time knowing about differences in ground level and obstacles below that you cannot see due to your reduced peripheral vision. People with vision loss from glaucoma tend to walk more slowly and bump into things more frequently. White canes help you focus on signs, waymarks, cars, and pedestrians rather than just looking down for walking safety.
    • Raised paint, stickers, tactile cues and permanent marker can be used around the house and on appliances to help you with your everyday chores and activities.
    • Large number phones, remotes and calculators make it easier for you to see to make phone calls, operate your entertainment system and for other daily tasks.
    • Large print and bold print materials are available to help with many activities of daily living. Today most print materials (books, magazines, newspapers, etc.) can be found in large print. You can get large print and bold lined checks to help with banking. There are large print calendars for keeping track of your schedule. You can even get notebooks and pads with bold lines and larger writing areas for you to write notes and keep track of things.
    • Typoscope, check writing templates, signature guides or line guides can be useful to help you keep your place while you read, write, sign documents or make out checks. Typoscopes are dark pieces of cardboard or plastic with a window cut into them that can be positioned over text to help you keep your place when reading or writing. Check writing templates and signature guides are like typoscopes with windows specifically designed to help you fill out a check or add your signature to a document. Line guides help you see, read or write along a straight line without losing your place.
    • Felt-tipped pens write bolder and are easier to see if you have vision loss.

    Higher Technology Low Vision Aids for People with Glaucoma

    Technology has made amazing advances in low vision aids to help people with vision loss from glaucoma succeed in doing all the things they used to do. Electronic aids include desktop, portable and handheld magnifiers, computer software, cell phone, tablet and camera apps, text-to-speech OCR software, and digital talking book readers. Below are just a few of the many low vision aids available for people with glaucoma. Also, be sure to call our hotline at 888-211-6933 for a consultation to learn about the hundreds low vision aids from 15 different vendors in one convenient place.

    HD CCTV Desktop Video Magnifiers

    HD CCTV desktop video magnifiers can be a great help if you have lost vision from glaucoma. These magnifiers capture images of what you want to see, and then send them to a screen where you can adjust them for size, lighting, focus and color.

    HD CCTV desktop video magnifiers give you a larger field of view so that you can see more at once, and you can adjust magnification levels to see as much or as little as you need. For example, HD CCTV Magnifiers allow you to see multiple words rather than having to read one word at a time.

    A Guide to Glaucoma (Part 4) Care Glaucoma If you have vision loss from glaucoma, you need low vision devices with the best HD (high definition) capabilities. With glaucoma-related vision loss you need to see small, not big. You need to minimize the size of what you are looking at so that it fits to what you are able to see (as if you are looking through a straw). The smaller you make the image, the clearer it needs to be. This is why HD is so important, because it helps you keep a clear image no matter how small you reduce the size.

    With HD even low power is still very sharp. This means that you can see small letters and details and maintain that crystal clear image no matter how small you minimize the letters. If you have an older CCTV that has weak or low power without HD, then it is time to consider an upgrade to a newer HD model.

    HD CCTVs are a great option for people with vision loss from glaucoma because they give you no distortion of the sides of the image (peripheral distortion) because the image is projected electronically on a screen so you can focus on any area that you want, all with equal clarity. There is no distortion to the sides of anything you magnify because it is an electronic image. Many CCTV magnifiers also offer guide lines and the ability to freeze the image so that you can focus on areas that you want to see.

    CCTV video magnifiers s allow you to adjust magnification to best suit your vision loss. They also come with multiple contrast and color modes to reduce glare and increase contrast. This helps you to read and see things better while reducing eye strain. They also often have built in lighting to help with tricky lighting situations.
