Dr Rinkov Helps Low Vision Patient To See Again With Iris Vision
Low vision patient able to see again with the help of Iris Vision
This patient suffers from dry macular degeneration and is unable to read, watch television or see her computer clearly. Dr. Rinkov fit her with a full diameter telescope for television with a Rx cap to place over her right eye for reading the computer. She was also fit with E scoop lenses with a yellow tint to reduce glare and to replace her former everyday glasses. These are custom lenses with a special curvature and thickness that enlarges objects slightly.
In addition, she was fit with bioptics. These are like having binoculars on the top of her prescription lens so she can see signs, cars and people much clearer and sooner.
Closed Circuit Television Magnifiers
CCTV magnifier is a combination of a camera and TV screen used to provide low vision aid for macular degeneration patients. The camera is pointed at an object while a magnified image will appear on the screen. The patient will be able to see the magnified image that appears on the screen and use it to work in real time.

Getting Your Life Back With Low Vision Glasses In Baton Rouge Louisiana
Low Vision doesnt have to rob you of the things you enjoy, such as watching TV, reading, writing, driving, socializing, or simply playing with your grandchildren. If Low Vision has affected you or someone you love, Low Vision aids or devices can help!
Watch this video to learn how Bioptic telescopic glasses work.
Bioptic telescopic glasses are one of the most popular Low Vision glasses. They are designed as miniature binoculars above your line of sight in your eyeglasses. Simply lowering your chin slightly allows you to access the magnification needed to see objects.
E-Scoop Glasses are ideal for compensating for Low Vision arising from Macular Degeneration. These glasses are specially designed to bridge the gap between regular glasses and telescopes. The glasses feature five basic components, including:
- Lens Thickness provides more magnification than regular glasses but less than telescopes
- Prisms adjustable strengths based on the patients needs
- Reflection-Free Lenses reduces glare
- Yellow or Amber tintreduces high-contrast glare such as nighttime glare
- Base Curve of Lens
These five components are combined into the E-Scoop lens. They work seamlessly to create an enhanced image shifted to another part of the macula. This allows the patient to enhance their vision.
At the , we have seen that many Low Vision patients choose the E-Scoop glasses over other devices, as they look and feel more like regular glasses.

What Are Reverse Telescopic Glasses For Patients With Retinitis Pigmentosa Or Glaucoma
Patients with visual field loss may benefit from reverse telescopic glasses. These little telescopes are carefully placed on top of the glasses. The patient can get better vision thanks to the telescope being mounted backward. This is made possible by minifying the patients remaining field of view. Looking backward through a pair of binoculars is a good analogy. The patient will be able to see a smaller but wider field of view as a result of this.
Telescope glasses in all their different forms and functions can really make a difference in a visually impaired patients life keeping them active and independent. Our doctors take pride in the time and quality of care they each provide to their patients. Give us a call to find the doctor closest to you.

The Low Vision Specialist
Its recommended that you see an eye doctor who is a low vision specialist to determine the right types of devices that will help you with the everyday tasks you want to perform. Some doctors may recommend starting with one or two devices to see how you manage, and then adding additional devices as you become used to working with the devices you have.
It is extremely helpful to both you and your doctor if you can make a list of the tasks or activities that are most important to you and share that information with him or her when you have a low vision eye exam. Its also helpful to bring along samples of your everyday tasks, such as mail, bills, or needlework.
The low vision service is incomplete unless youve been taught how to use the devices that have been prescribed for you. After youve been prescribed low vision devices, such as a magnifier or telescopic glasses, its important to learn how to use them when you get home.
Before any optical or non-optical device can be effective and comfortable, you will need to:
- Be motivated to use the device for specific tasks
- Be confident that the device has been appropriately prescribed
- Understand how to maximize the use of the device
- Understand the potential and limitations of the device.
Low vision optical devices can be grouped into two basic categories:

Macular Degeneration Glasses For Distance
Macular degeneration glasses for distance vision are as important as magnifiers are for reading. These glasses make it possible to watch TV, recognize faces, see street signs, enjoy a play, are cheer for your favorite sports team.
The macula, the central part of our retina is responsible for seeing detailits the part of the eye that give us our normal 20/20 vision. Macular degeneration, diabetes as well as other retinal and optic nerve disorders reduce the ability of the macular to function, and hence sharp central vision becomes reduced.
Individuals with reduced vision are said to have Low Vision which is usually defined as visual acuity of less than 20/70 that does not respond to medication, surgery, eyeglasses or contact lenses. While new treatments for macular degeneration hold great promise in controlling the progression of the disease sometimes even improving some of the vision loss, treatment is not yet able to return vision to normal.
Despite the vision loss experienced from macular degeneration, the world will not go dark. Peripheral vision remains normal allowing individuals to walk and engage in many normal activities. Our peripheral vision is sensitive to motion and works best in low light but it does not provide the sharp vision needed for reading and other fine detail tasks.

Most Common Types Of Low Vision Problems
Low vision can interrupt the visual capabilities of anyone who has had an eye injury or an eye disease, but people aged over 45 become potentially vulnerable to develop low vision due to eye conditions like age-related macular degeneration etc.
44 million Americans over the age of 40 are near or farsighted as reported by The New York State Department of Health and whereas Only half of the 93 million US adults at high risk for vision loss visited an eye doctor in the past 12 months reported in The Centers for Disease Control and Prevention 2020.
Low vision can appear as various form of visual difficulty, some of them include:
- Central Vision LossCentral vision loss appears as a loss of sight in the center of your visual field. It may begin as blurred spots which progressively turn into dark or blind spots.
- Tunnel visionTunnel vision is caused by peripheral vision loss in which only the center of your visual field is clearly seen, as if looking through a narrow tunnel.
- Night Blindness
- The image that you see appears to be covered with a haze.
Other Low Vision Aids
Nowadays, computers are essential in how we communicate, acquire information, and engage with the world. However, those suffering from Low Vision struggle to read from computer screens.
Fortunately, there are advanced programs designed for Low Vision and the Visually Impaired which adjust the visual output of the computer to compensate for these problems. Low Vision software includes JAWS Screen Reader and MaxiAids, among others.
Also referred to as closed-circuit television , video magnifiers make use of a handheld or stand-mounted camera to enlarge and project an image onto a screen. These video magnifiers often feature cameras which include zoom lenses. Video magnifiers can also be useful in distinguishing colors, such as maps, color photographs, and so forth.
The CCTV consist of a camera, viewing screen or monitor, mount arm for the camera, and lenses for zooming. Viewing modes with color, lighting, and contrast provides improved vision.
Handheld magnifiers are portable devices that help to magnify objects by 1.5x 20x. One can conveniently tuck the magnifier into your pocket or purse. Some feature battery-powered lights.
Handheld magnifiers can help Low Visions patients to enhance their reading and viewing ability.
The stand magnifier is a plus lens mounted on a stand. The lens magnifies objects by 2x-20x. The majority of stand magnifiers now feature built-in lights that provide excellent illumination. Stand magnifiers are an excellent option for reading.

What Is Low Vision
Low vision is the loss of eyesight which is not correctable with prescription eyeglasses or contact lenses, and this loss of vision is typically due to eye diseases such as macular degeneration, glaucoma, diabetic retinopathy etc.
There may be different degrees of vision loss for people with different eye conditions, based on which The World Health Organization has defined different classifications for low vision i.e.
- Mild vision loss or near-normal vision: 20/30 to 20/60
- Moderate visual impairment or low vision: 20/70 to 20/160,.
- Severe visual impairment or low vision: 20/200 or worse
- Profound visual impairment, or low vision: 20/500 to 20/1000
- Near-total visual impairment or low vision: Less than 20/1000
- Total visual impairment or blindness: No light perception
I Have A Magnifier And It Doesnt Work
This is a very common comment from many low vision patients.
Family members and friends do not want to see their loved ones struggling, so they will often buy a magnifier hoping that it will help. This is a lovely gesture, but a large percentage of the time is a failed attempt.
In order to purchase a magnifier or any low vision device the level of vision must be known in order to determine the appropriate power required, otherwise we end up with a device that is too powerful or not powerful enough. Also, the person should be taught properly how to use the device or they will not get the most benefit from the device.
With magnification, not only does it make objects larger, but it also requires that we hold our work a lot closer. For those of us with no difficulties with our vision, we normally hold reading materials etc. somewhere between 30-50cm . When using certain low vision devices, materials have to be held much closer, 25 cm to almost touching the nose.

Fixed Focus Autofocus And Manual Focus Bioptic Telescopes
Among the different types of Bioptics, there are three different focusing types. The Galilean comes in a fixed focus and manual focus setup. The Keplerian can be made in all three styles including one made by a company called Ocutech which is an autofocus telescope. They are awesome because you can look at any distance and have it in focus.
Ost Of Bioptic Systems
The cost of these special glasses can vary greatly depending on several factors.
- The lens coatings on the carrier lenses
- If it is fixed, manual, or autofocus
- If there are lens caps for occlusion or reading in the case of Galilean scopes.
As a general rule, most Bioptic telescopic glasses will cost between $1500-$4000. The good news is they tend to be less than hearing aids.

Galilean And Keplerian Telescopes
There are two types of telescopes used in bioptics. The Galilean telescopes are used when the magnification need isnt more than about 3x. When the magnification needed is more than this it is best to use the Keplerian telescopes instead. This is because the field of view becomes very small with the Galilean telescopes as the magnification increases. The keplerian style uses a more complex mirrored system. This makes them bulkier but helps to maintain the field of view.
Low Vision Glasses For Retinitis Pigmentosa And Glaucoma
IrisVision low vision headset has a special feature that compensates for the loss of peripheral vision in Retinitis Pigmentosa and glaucoma. It shrinks your field of view to a smaller area, and lets you move the camera across your visual field allowing you to see better despite your eye condition.
The effects of eye conditions listed above can be mitigated through the use of specialized software lenses such as Bioptic mode that allows you to focus on the specific area without losing the entire field of view serving as the ideal bioptic glasses for low vision.

Our low vision glasses and devices come in a wide range of designs and powers. They range from simple handheld magnifying lenses and advanced electronic devices, to state-of-the-art telescope glasses and more. After your initial consultation, Dr. Harold Ashcraft will ensure that the recommendations are personalized to meet your specific condition as well as lifestyle needs and diverse visual requirements.
What Are Bioptic Telescope Glasses
During activities that need both mobility and greater central vision, Bioptic Telescope eyeglasses provide the benefits of a telescopic system but still allow you to move around. The telescopic system comes in a range of sizes, shapes, colors, and magnification capabilities. They can be produced in a variety of frames to meet the demands of the patient. The patient and the eye doctor collaborate to determine the optimal system for the task and activity. Our patients have utilized their bioptic glasses for a variety of chores and activities, including driving, watching movies, attending to a play, playing cards, and simply seeing faces.
Distance vision is necessary for social engagement, and its loss may reduce ones quality of life. The inability to interpret body language or establish eye contact may be isolating and depressing for individuals who are blind or visually impaired. Distance vision loss has a significantly greater impact on independence and self-worth more than reading loss, and it is not easily substituted by other modalitiesno one can see your friends and family for you.

The Telescopic Lens Can Zoom And Magnify An Image
Miniature binoculars or a monocular is mounted at certain positions on the glasses. This addition of single monocular or miniature binoculars allows the telescopic lens to magnify and zoom an image. This is especially beneficial for people who have a visual acuity of 0.3 below. By simply adjusting the position of the head or direction of the eyes the wearer can see better by looking through the strategically placed telescopic lens.
