Vision loss may occur gradually or suddenly due to eye disease, injury or aging, so low vision supplies include devices which maximize usable vision so people can watch television programs, recognize faces and read books with greater ease as well as complete everyday tasks more successfully.

Low vision supplies available include handheld magnifiers and illuminated reading telescopes that attach directly to regular glasses lenses, along with glare-reducing lenses in both nonprescription sunglasses and prescription versions of “fit overs”.

Optical Magnifiers

Optic magnifiers are one of the most widely used low vision aids. These hand-held devices with lenses that can be powered either by batteries or electricity are typically simpler and cheaper than electronic magnifiers, offering greater versatility than simple handheld magnifying glasses or glasses that fit onto spectacle frames; depending on user requirements they may also come equipped with illumination features or not.

Optic magnifiers can help improve reading and other near vision tasks, though they will not restore vision to normal. To determine what level of magnification will work best for your condition and needs, discuss this matter with an eye care provider – this way they can eliminate options which won’t fit.

Your eye care professional may recommend various low vision aids that could be helpful, such as large print books and high contrast computer themes. Portable electronic magnifying systems known as personal electronic visual enhancement systems (p-EVESs) could also be suggested.

Electronic glasses that operate using batteries allow users to magnify text on a computer screen by increasing its size. Users can program these glasses either automatically magnify the screen or zoom in on objects and text; additionally they may be programmed to read aloud text aloud if that feature is preferred by their user.

Researchers recently conducted a study that demonstrated how handheld illuminated optical magnifiers could be effective at short-duration spot reading in visually impaired people. Their performance was evaluated against various traditional magnifiers to compare reduction of activity limitation for near vision tasks.

Results suggest that p-EVES devices may reduce the need for other low vision aids such as reading glasses or electronic devices. It’s important to keep practicing reading, other activities that require close-up vision such as art or sport or simply doing things such as watching television regularly in order to maintain close vision abilities; otherwise reading ability will gradually decline with time.

Non-Optical Electronics

As vision declines with age or an incurable eye disease, daily activities may become increasingly challenging. But many people with low vision still retain some residual vision that can be harnessed through non-optical devices to enhance their quality of life and help with reading, writing and cooking tasks. A wide variety of non-optical devices is available that can assist people with low vision to perform all sorts of tasks more easily.

Devices available include handheld magnifiers, closed-circuit television (CCTV) systems, video cameras and smartphone apps that help enhance near vision. More sophisticated optical and non-optical devices include portable electronic vision enhancement systems (pEVES). These portable electronic vision enhancement systems enlarge text, images and documents hands free via digital camera or monitor attachment – an increasingly popular solution to improve near vision.

Electronic low vision aids also include portable video magnification (pVM). This device is used for reading, watching TV, and listening to music – battery powered models are small enough to fit easily in purses or backpacks, though you could also attach one directly onto a desktop computer for hands-free operation.

Low vision sufferers can benefit from special software designed to enable them to customize text sizes, font styles and image contrast settings on printed materials as well as digital images. Such programs can be purchased at computer stores, online retailers and specialty websites – some programs even integrate seamlessly into smart devices such as smartphones and tablets through accessibility settings.

Environmental modifications and non-optical devices may also help improve visual function. For instance, tables with adjustable tilt can help correct poor posture caused by short viewing distances and neck bending; felt-tipped pens that create thicker lines may benefit children with media opacities; while those with glare sensitivity could use absorptive filters and hats to minimize scattered and glare-producing light.

Low vision specialists can assess a person’s needs and recommend appropriate equipment, while also teaching how to use their new device – usually included within the cost of an evaluation. Trial runs of these devices should also be scheduled soon after receiving your assessment report.

Magnifying Glasses

Magnifying glasses provide an effortless yet efficient solution for many of the visual challenges experienced by people with low vision. These devices feature lenses to magnify and reduce images as well as prisms to bend light and expand field of view, making it easy and convenient for anyone seeking greater independence and increased daily functionality. They can be worn standalone glasses or mounted onto eyeglasses.

Prismatic glasses stand out as an invaluable low vision aid, offering tailored optical solutions for an array of visual impairments. By employing prisms to alter the path of light as it enters the eye, these devices can eliminate issues with vision loss, glare, double vision and visual field loss experienced by those suffering macular degeneration or central vision loss.

Reading telescopes provide another useful solution for those seeking to recover their ability to read printed materials. Crafted with portability and convenience in mind, these telescopic devices boast various features designed to assist visually impaired individuals comfortably read books, labels and more. Depending on the model chosen they may include features like high approach magnification, lighting effects, a swivel base or support stand, as well as even an inbuilt camera to capture and freeze images for later review.

Non-optical reading aids can be equally as useful for those living with visual impairment. Such devices include handheld magnifiers that can enlarge print for reading and other close-up tasks, often illuminated for optimal clarity, in various sizes to suit a wide variety of hands and equipped with special high-power reading lenses to increase magnification or even single or bifocal designs.

Non-optical magnification devices also include video magnifiers, which use digital technology to enlarge materials and project them onto a monitor for viewing. Connected directly to either a computer or television screen, video magnifiers are an invaluable resource that can be used for everyday duties such as reading mail and completing crossword puzzles – greatly increasing quality of life while providing greater autonomy.

Glare-Reducing Lenses

Many individuals who are blind or visually impaired experience a decline in their visual capabilities as a result of eye disease or other conditions, often permanently. But with low vision supplies, materials, and devices to aid them, their remaining visual capacity can still be utilized most efficiently.

Tinted and selective transmission lenses are available to address various forms of visual impairments. These lenses include those which reduce glare, blue light filtering capabilities and photochromic lenses that lighten or darken depending on sunlight exposure. They can be worn loose or mounted into frames as nonprescription clip-ons for existing glasses.

Glare-reducing lenses typically use tinting to dim reflected light from bright sunlit roads or bodies of water, such as that from bright sunlit roads or bodies of water. Some lenses also filter out blue light (which has been known to cause most glare) before adding another tint for contrast enhancement and filtering out blue light (known to cause most glare). Other glare-reducing lenses are polarized to reduce flat surfaces like snow or wet roads causing excessive reflections of light.

These lenses also include anti-reflective coating to minimize reflected glare and create an appearance of thinner, more transparent lenses with a more natural appearance.

An alternative way to reduce glare is using polarized lenses with high-index plastic or polycarbonate substrate. These types of lenses feature a higher refractive index than regular lenses and allow more light through, improving optics for distance and intermediate vision as well as making it easier to see through when turning your head.

Telescopes are an extremely helpful low vision device for helping individuals with near-sightedness or far-sightedness complete tasks that require close attention, such as reading or navigating rooms. Available with magnification powers ranging from 2x to 10x (with some models designed specifically for distance tasks such as distance reading or intermediate tasks and others designed specifically for near tasks), telescopes come in hand-held models (handheld hanging stand models) as well as lighted hand-held or clip-on designs that make use more convenient than reading glasses alone.
