Low Vision Rehabilitation
What Is Low Vision Rehabilitation?
If—despite appropriate surgical and medical treatment—the remaining visual function does not meet a person’s daily life goals and needs, the individual is considered to have low vision. Low vision rehabilitation aims to improve quality of life by using appropriate devices and methods. It is planned individually for each person.
What Causes Low Vision?
Low vision may result from any eye disease and/or systemic disease that negatively affects visual functions—especially visual acuity and the visual field.
What Are the Symptoms of Low Vision?
Inability to see near clearly despite regular reading glasses; difficulty reading books
Inability to see far clearly
For students: inability to see the board, difficulty reading books
In babies and young children: eye shaking (nystagmus), eye deviation (strabismus), inability to make eye contact
Reduced vision in the dark
Discomfort from light
Color vision disturbances
How Is Low Vision Rehabilitation Performed?
Rehabilitation is planned individually according to the underlying condition and the degree of visual impairment. It may involve:
Optical or digital low-vision aids (e.g., telescopic glasses, microscopic glasses, telemicroscopes)
Methods such as microperimetry, depending on clinical need
Frequently Asked Questions
What Is the Difference Between Low Vision and Total Blindness?
Low vision means vision is not completely lost, but is significantly limited to the extent that daily life becomes difficult. In total blindness, there may be no light perception at all.
Why Does Vision Become Low?
Causes of low vision vary depending on damage within the eye or along the visual pathways. These conditions are often progressive, and if not addressed early, can lead to permanent vision loss. Therefore, regular eye examinations are critically important.
Who Is Low Vision Rehabilitation For?
Low vision rehabilitation is used for individuals whose vision remains insufficient for daily activities despite glasses, contact lenses, medication, or surgery. This may include:
Older individuals with age-related vision loss
Children born with vision loss or who develop vision loss in childhood
Patients who lose vision due to trauma or neurological causes
Rehabilitation is delivered through customized programs based on the person’s age and the type of vision loss.
What Are the Common Types of Low Vision Impairments?
Low vision refers to inadequate functional vision for daily life despite corrective lenses, medications, or surgery. Common patterns include:
1) Central Vision Loss
Characterized by blurring or a blind spot in the point you focus on. Peripheral vision is often preserved. This makes:
Reading
Recognizing faces
Seeing fine detail at distance
more difficult. Mobility is often largely preserved if peripheral vision remains intact.
2) Peripheral (Side) Vision Loss
Central vision may remain, but the side vision is reduced. Because the visual field is narrowed:
Orientation and mobility can be affected
In severe cases, “tunnel vision” may develop and reading speed can decrease
3) Blurred Vision
Even with glasses, focusing is difficult at both near and far distances. Images may appear hazy, unclear, and scattered.
4) Reduced Contrast Sensitivity
Difficulty distinguishing objects from the background. Vision may feel as if a “hazy film” is covering everything, and this is often worse in dim environments.
5) Glare and Light Sensitivity
Even normal light levels may interfere with vision. Bright light can cause washed-out images or uncomfortable glare, and in some individuals may cause pain.
6) Night Blindness
Difficulty seeing in low-light settings, especially outdoors at night or in dim interiors. The eye’s adaptation to darkness is reduced.
These impairments can be managed with low vision rehabilitation. Early diagnosis and appropriate rehabilitation approaches can significantly improve independence and participation in daily life.
