At older ages, vision loss becomes increasingly prevalent worldwide. Although some cases can be corrected using medication or surgery, others remain permanent.

Eye care practitioners can assist patients in reclaiming function and hope through adaptive technologies such as low vision supplies. These devices are designed to magnify objects for easier reading.

Optical Magnifiers

Optic magnifiers are among the most widely used low vision aids. These devices may be handheld or attached to spectacle frames for convenient use when reading, writing or performing other near vision tasks like sewing and knitting. Magnifiers typically range in magnification power from 1.5x to 20x; some models even allow connections with computers! Optical magnifiers tend to be relatively inexpensive, cosmetically acceptable devices that provide ample working distance; however they may not be appropriate for individuals suffering from significant hand tremor or who cannot use their hands effectively.

Stand magnifiers provide a broad spectrum of powers (1.7X to 8X), making them suitable for hobbies like sewing and knitting. You can hand hold or mount them on a stand with legs – with the latter option offering both hands free to complete their task at the same time while still offering good working distance and field of view.

Telescopes are another form of optical magnifier used for near tasks; however, they’re less comfortable to wear than handheld magnifiers. Telescopes come in three varieties – hand-held, clip-on or spectacle mounted – offering single or binocular magnification options and some models even connect to computers to increase functionality.

Closed-circuit television systems (CCTVs) are electronic low vision aids that can be worn over one eye for enhanced magnification and contrast enhancement with a wider viewing area than handheld optical magnifiers. Furthermore, these wearable devices can also be worn on the head – perfect for people involved in multiple activities that require near vision and who require mobility.

Video magnifiers offer a more portable alternative to closed-circuit television systems, though their viewing screens and magnification levels tend to be smaller and lower compared to handheld optical magnifiers. They may also feature limited features like being unable to enlarge only certain parts of an image and typically display only monochrome pictures; nevertheless they may serve as useful supplements when combined with optical devices to meet complex reading and writing needs.

Non-Optical Electronics

Non-optical devices do not magnify objects; rather they control lighting or improve contrast to help individuals with vision loss interact with mainstream technology more easily; such as searching information online, taking photographs/video footage, checking weather and time updates, opening applications or opening programs – such tools may be used with or without optical aids.

Optic low vision aids are specifically designed to aid with near tasks and can be divided into magnification systems or hand magnifiers, while line trackers make text easier to read by displaying one section at a time. Such electronic devices can assist in reading newspapers, books and magazines among other forms.

Other electronic devices available today include mobile video magnifiers that can be brought from location to location for greater flexibility than optical magnifiers. These portable video magnifiers can be found in schools, work environments and restaurants and may feature foldable designs that allow easy storage and transportability.

Non-optical low vision aids may also include visual aides like tactile materials or raised dots that help with activities of daily living, either alone or in combination with Braille. They can be utilized for educational, recreational, or vocational use.

Before choosing to utilize a low vision aid, it’s essential to assess a child’s lifestyle and ability to use the device properly. If your child struggles to adapt quickly enough, training from an optometrist or other trained professional might be best suited for them.

Optometrists provide more than just clinical low vision exams; they also refer patients and families to social services and vision rehabilitation specialists such as orientation and mobility (O&M) instructors who know how to teach children how to use optical devices correctly. Furthermore, they can assist families and patients in finding funding sources for low vision aids as well as services – all while informing families on the importance of keeping records and following progress reports for each child in care.

Customized Low Vision Aids

Optometrists can assist patients suffering from visual impairment by providing prescriptions for low vision aids to meet individual needs and provide personalized recommendations – these products include both optical and non-optical aids available in various styles, sizes, and power configurations.

Hand-held magnifiers may offer just the right level of magnification to aid with spot reading, as well as features such as brightness and contrast enhancement that improve viewing comfort.2

Desktop electronic low vision aids such as CCTV systems are generally stationary devices that offer adjustable magnification levels and lighting control options, along with OCR/text-to-speech technology to assist reading. These devices tend to be large and heavy and typically used either at home or libraries.

People with low vision often need to move closer in order to see objects more clearly, making a bioptic telescope an excellent solution for visual impairment as it helps them focus on objects at any distance while providing enough light for an easy view. This enables users to read, play games, use computers and complete other tasks more effectively.

Low vision technology includes advanced autofocused telescopic devices, portable electronic magnifiers, wearables and character readers that are revolutionizing eye care services and helping individuals living with visual challenges live fuller, more independent lives.

People living with low vision should understand that any device they receive does not guarantee full recovery of sight. Instead, they will still require consultation with a low vision specialist who can recommend appropriate aids and train users on how best to utilize them. In addition, follow-up visits should take place regularly to make sure everything is going according to plan and that their daily activities don’t interfere with its use.

Optometrists and eye care professionals can take an integrated, multidisciplinary approach to low vision rehabilitation to assist their visually impaired patients lead a healthier lifestyle. Optometrists can enlist occupational therapists, orientation and mobility specialists and mental health professionals as part of an interdisciplinary plan of care to support their visually impaired clients more fully.

Wearable Devices

Monitoring health aspects through technology could prove revolutionary in helping both patients and healthcare professionals gain an accurate picture of a person’s overall condition, track data points in real time and create personalized treatment approaches.

Assistive technologies exist for those living with low vision, as well as those suffering any type of visual impairment. Low-tech options include magnifying glasses and other optical devices; high-tech options include adaptive technologies like computers, tablets and smartphones with built-in accessibility features for visually impaired users such as magnified screens and text-to-speech capabilities. In addition, software programs exist which provide assistance with tasks like reading, writing, computer navigation and online activity.

These tools can enable people with low vision to use the internet and stay in touch with family and friends. Many are portable, easy-to-use technologies that can easily fit in a purse or pocket; one such technology, the portable electronic video magnifier can be adjusted for specific tasks – reading small print, solving crossword puzzles or seeing better for other activities like cooking or shopping are just some uses of its features.

Some technologies can even be used to monitor vital signs, such as blood pressure, heart rate and glucose levels of an individual. A physician can use these tools to quickly recognize any changes and provide immediate medical treatment as soon as an emergency situation arises – potentially saving their vision in an emergency situation and helping avoid further complications.

Although these devices provide numerous benefits, they may also present numerous challenges to users. When selecting an assistive technology device for someone, it’s essential that lifestyle considerations and use are considered when making recommendations. Furthermore, users may require training before being able to use these products effectively – an instructor from San Diego Center for the Blind recommends finding a local dealer who can demonstrate and train patients on these products.
