Freedom Scientific - Solutions For The Visually Impaired
For over 20 years Freedom Scientific has provided access to print and computers for individuals with blindness and low vision. Our innovative technology is designed to promote independence, allowing blind and low vision individuals the same access to information as their sighted peers. Our team is passionate about what we do and committed to the communities that we serve.
Low vision is a visual impairment that cannot be fully corrected with regular eyeglasses, contact lenses, medication or surgery. Despite all conventional treatment, vision remains blurred or distorted, and it interferes with the ability to perform every day activities such as reading, writing, and shopping. Millions of Americans lose some of their vision every year due to a variety of eye conditions such as Diabetic Retinopathy, Glaucoma, Macular Degeneration or Retinitis Pigmentosa. If you are among the growing number of people living with low vision, you can still live independently with the help of low vision aids.

Macular Degeneration is a medical condition often associated with aging (also referred to as “age-related Macular Degeneration”) that results in a loss of vision in the centre of your visual field. Central vision helps us to see objects clearly and perform tasks such as reading and driving. - Credit: Optelec
Glaucoma is an eye condition in which the optic nerve is damaged, causing vision loss. The optic nerve is located at the back of the eye and transmits the images we see to the brain for interpretation. Glaucoma results in progressive damage to the optic nerve, which almost always begins with a subtle loss of peripheral (side) vision.
Diabetic Retinopathy is a complication brought on by diabetes where the retina, the lightsensitive tissue that lines the inner surface of the eye, is damaged. Diabetes causes abnormal changes in the body’s blood sugar levels. High levels of blood sugar can alter the blood flow to the body’s organs, including the eyes. - Credit: Optelec
A cataract is a clouding of the eye’s natural lens. Our eyes’ lens is mainly made up of water and protein. The proteins are arranged in such a way that the lens stays clean and light is able to pass through. As we grow older, some of these proteins may clump together and start to cloud a small area of the lens. This is a cataract.
Retinitis Pigmentosa is a group of genetic eye conditions causing progressive degeneration of the retina, the light sensitive layer of tissue lining the back of the eye. The light receptors of the retina are called rods and cones. As a result of Retinitis Pigmentosa the rods, and in a later stage the cones, slowly die, causing reduced vision. - Credit Optelec
Blindness is the state of being sightless. A blind individual is unable to see. Some may have a limited ability to see objects using special aids or may be able to perceive light or a light source. All people who are blind experience sightlessness to various degrees. Blindness can be the result of a variety of causes. - Credit Optelec
Strabismus is an eye condition in which the eyes are not aligned properly and point in different directions. One eye may look straight ahead, while the other may turn inward, outward, downward or upward. The manner in which the eye turns may be consistent or it may vary. Which eye is straight and which eye turns may also differ. - Credit: Optelec
Nystagmus is an uncontrolled and involuntary movement of the eyes. The movement is often side to side (horizontal) but it can also be up and down (vertical) or circular (rotary). The movement can vary between slow and fast and almost always involves both eyes. - Credit: Optelec
Leber's Hereditary Optic Neuropathy (LHON) is a genetic eye disease which leads to a sudden loss of central vision. While the condition usually emerges in a person's teens or twenties, rare cases may appear in early childhood or later adulthood. For unknown reasons men are more affected than women. - Credit: Optelec
Ocular tumors are tumors inside the eye. They do not occur frequently, but when they do, they will often grow on the coloured part of the eye, called the iris, or in the back of the eye. Left untreated, ocular tumors can not only threaten your vision, but also your life.- Credit: Optelec
Keratoconus is a progressive eye condition in which the cornea of the eye thins and begins to bulge into a cone-like shape. The cornea is the transparent front part of the eye that covers the iris, pupil and anterior chamber. Together with the eye’s lens, the cornea reflects light. The cornea is responsible for approximately two-thirds of the eye’s total optical power. Credit: Optelec
Graves’ Disease is an autoimmune disease in which the thyroid gland is overactive, producing high levels of thyroid hormones. These high levels of thyroid hormones are referred to as hyperthyroidism. In a small percentage of people with Graves’ Disease, the fat and muscle behind the eyes are also affected, causing various symptoms. - Credit: Optelec
Color blindness is the inability to distinguish the differences between certain colors. Color blindness results from an absence of color-sensitive pigment in the cone cells of the retina, the nerve layer at the back of the eye. - Credit: Optelec
Choroideremia is a genetic condition that causes progressive loss of vision due to degeneration of the retina and the choroid. Night blindness is the most common first symptom. As the disease progresses, there is loss of peripheral vision (tunnel vision) and later a loss of central vision. - Credit: Optelec
Albinism refers to a group of conditions in which people have little or no pigment in their eyes, skin or hair. Albinism occurs due to inherited altered genes which do not make the usual amounts of pigment called ‘melanin’. Based on the amount of melanin in the eyes, different types of albinism can be distinguished. What the different types have in common is that they are all associated with vision problems. - Credit: Optelec
Refractive errors are errors in which the eye’s ability to focus light is affected, causing reduced visual capacity. This is the most common and well-known eye condition including various types.- Credit: Optelec
Stargardt’s Disease is an inherited eye disorder that causes loss of central vision at a young age. It affects the macula, the area of the eye responsible for central vision and seeing colour and fine details. The symptoms are very similar to Age-Related Macular Degeneration. Stargardt’s Disease causes progressive vision loss and, in some cases, near blindness. - Credit: Optelec
Usher Syndrome is the most common condition affecting both vision and hearing. It is a rare genetic disorder that is the main cause of deaf-blindness. The major symptoms of Usher Syndrome are loss of hearing and an eye condition called Retinitis Pigmentosa. - Credit: Optelec
