Meet Howard Truman – an OrCam User

“The first thing I wanna try to do when I get home, is read the things that are inside my refrigerator", says Oscar Snell, an OrCam user, in this ABC Tech video. Turman, who is legally blind, started losing his vision when he was a child. OrCam’s smart devices which were specially tailored for blind people do not fix his sight but they do provide audible information of visual data. OrCam devices are built using OCR technology to read text from any printed or digital surface. Making reading available again for its users.

In addition, it can recognize faces, barcodes, personal items, colors, and even money bills. These features allow the tens of thousands of OrCam’s users worldwide to get back to work, shop independently, and even raise their children on their own as blind parents.

Why do blind people wear sunglasses?

Reasons for wearing sunglasses

Some blind people choose to wear sunglasses for various reasons. Here are a few common reasons:

1. Protection from glare and brightness: Blind individuals often have heightened sensitivity to light, and wearing sunglasses can help reduce the discomfort caused by glare. Sunlight, artificial light, or even reflections can be overwhelming, and sunglasses provide a shield that allows blind people to manage their surroundings more comfortably.
2. Eye protection: Sunglasses serve as a protective barrier for the eyes, shielding them from dust, wind, and debris. For blind individuals who may rely more on touch and tactile cues, sunglasses provide an added layer of defense to prevent potential eye injuries.
3. Privacy and social comfort: Wearing sunglasses can offer a sense of privacy and anonymity for blind people. In social situations, sunglasses help prevent others from making assumptions about their visual impairment, allowing them to navigate social interactions on their own terms.

Benefits of sunglasses for blind individuals

1. Glare reduction: Sunglasses with tinted lenses can significantly reduce glare, making it easier for blind individuals to perceive their surroundings and navigate comfortably. By minimizing glare, sunglasses enhance their visual comfort and may even improve their ability to detect objects or obstacles.
2. Increased contrast perception: Certain types of sunglasses, especially those with specialized lenses, can enhance contrast perception. This feature can be particularly beneficial for blind individuals who have residual vision or those who rely on light and shadow cues to interpret their environment.
3. Eye health: Prolonged exposure to ultraviolet (UV) rays can be harmful to the eyes, regardless of visual impairment. Sunglasses with UV protection help shield the eyes from harmful rays, reducing the risk of conditions such as cataracts and macular degeneration.

Social and psychological aspects of wearing sunglasses for blind people

1. Confidence and self-expression: Wearing sunglasses allows blind individuals to present themselves with confidence and express their personal style. By choosing sunglasses that suit their preferences, they can enhance their self-image and feel more comfortable in public settings.
2. Reduced stigma and misconceptions: Sunglasses can help alleviate some of the stigma associated with visual impairment. By concealing their eyes, blind individuals may avoid unwanted attention or intrusive questions about their condition, allowing them to focus on their daily activities without unnecessary distractions.
3. Facilitating social interactions: Wearing sunglasses can act as a social cue, signaling to others that an individual has a visual impairment. This can lead to increased understanding and consideration from those around them, making social interactions smoother and more inclusive.

Remember, while these reasons and benefits apply to some blind individuals, preferences may vary. It's important to respect individual choices and consult with eye care professionals to determine the most suitable eyewear for each person's specific needs.

Glasses for the visually impaired

Types of glasses for individuals with varying degrees of visual impairment

There are different types of glasses available to assist individuals with varying degrees of visual impairment. These glasses are designed to address specific visual needs and can significantly enhance visual acuity and comfort.

Correcting refractive errors and enhancing visual acuity

Glasses play a crucial role in correcting refractive errors such as nearsightedness, farsightedness, and astigmatism. By prescribing lenses with the appropriate power and curvature, optometrists and ophthalmologists can help individuals with visual impairment achieve clearer and sharper vision.

In addition to refractive correction, glasses can also incorporate specialized lenses or technologies to enhance visual acuity. These may include:

1. High-index lenses: These lenses are designed to be thinner and lighter, providing greater comfort for individuals with stronger prescriptions.
2. Progressive lenses: Also known as multifocal lenses, these glasses provide clear vision at different distances, allowing individuals with presbyopia to see both up-close and far away without the need for multiple pairs of glasses.
3. Anti-reflective coatings: These coatings minimize glare and reflections on the lens surface, improving visual clarity and reducing eye strain, particularly in challenging lighting conditions.

Specialized lenses and technologies for maximizing remaining vision

For visually impaired individuals, glasses can incorporate specialized lenses or technologies that aim to optimize their remaining vision. Some examples include:

1. Tinted lenses: Tinted glasses can help individuals with certain visual conditions, such as light sensitivity or color deficiency, by reducing glare and enhancing contrast.
2. Prism lenses: Prism glasses are used to correct specific eye alignment issues or improve binocular vision. They can help individuals with conditions like strabismus or amblyopia.
3. Electronic magnification: Some glasses feature built-in electronic magnification systems, which allow users to adjust the level of magnification according to their needs. This technology can assist individuals with low vision in reading and performing daily tasks.

Glasses for the legally blind

Understanding the term "legally blind"

The term "legally blind" refers to a level of visual impairment that is severe enough to significantly impact an individual's ability to perform daily activities, even with the use of glasses or contact lenses. The criteria for being considered legally blind may vary by country or jurisdiction but typically involve having a visual acuity of 20/200 or worse in the better eye, or a visual field of less than 20 degrees.

Assisting legally blind individuals with glasses

Legally blind individuals face unique challenges due to their significant visual impairment. However, glasses can still play a valuable role in assisting them. While glasses alone may not fully restore vision, they can provide benefits such as:

1. Magnification: Glasses can incorporate magnifying lenses or electronic magnification systems that help individuals with low vision read small print, view objects more clearly, and perform tasks that require detailed visual acuity.
2. Contrast enhancement: Certain glasses can enhance contrast and improve visibility for legally blind individuals, making it easier to distinguish objects and navigate their environment.
3. Integration of low vision aids: Glasses can be designed to accommodate and integrate various low vision aids and devices. These may include telescopic lenses, prismatic lenses, or miniature electronic devices that provide additional visual support.

Low vision aids and devices incorporated into glasses

To aid the visually impaired, glasses can be combined with low vision aids and devices that offer supplementary support. Some examples include:

1. Microscopes and telescopes: These attachments can be incorporated into glasses to provide magnification for tasks requiring fine details or long-distance viewing.
2. Electronic visual aids: Glasses can integrate electronic devices that utilize advanced technologies, such as image enhancement, contrast enhancement, or augmented reality, to assist individuals with low vision.

By combining glasses with these low vision aids and devices, legally blind individuals can gain improved functionality and independence, allowing them to navigate their surroundings with greater confidence.

Note: It is important for visually impaired individuals to consult with eye care professionals or low vision specialists to determine the most appropriate glasses and low vision aids based on their specific visual needs and preferences.
