Low Vision
What does low vision mean?
Low vision refers to a visual impairment that makes it challenging to perform daily tasks. This condition cannot be corrected with conventional methods such as glasses, contact lenses, or typical medical treatments like medications or surgical procedures.
You might be experiencing low vision if you struggle to see adequately for activities such as:
Reading
Driving
Identifying people's faces
Distinguishing between colors
Viewing your television or computer screen clearly
What are the various types of low vision?
The specific type of low vision you have is determined by the underlying disease or condition that led to it. The most prevalent forms of low vision include:
Central vision loss (inability to see objects in the center of your visual field)
Peripheral vision loss (difficulty seeing objects at the edges of your vision)
Night blindness (inability to see in dim lighting)
Blurred or hazy vision
What are the causes of low vision?
Numerous eye conditions can lead to low vision, but the most frequent causes include:
Diabetic retinopathy (a condition that may result in vision loss for individuals with diabetes)
Low vision is more prevalent among older adults, as many of the conditions that can lead to it are more common in this age group. However, aging itself does not directly cause low vision.
Injuries to the eyes and brain, along with certain hereditary disorders, can also contribute to low vision.
How will my eye care professional assess low vision?
Your eye doctor can evaluate for low vision during a dilated eye examination. This procedure is straightforward and painless. Your doctor will ask you to read letters from both near and far distances and will assess your ability to see objects in the center and at the periphery of your vision.
Afterward, they will administer eye drops to dilate (enlarge) your pupils and check for additional eye issues, including conditions that might lead to low vision.
What treatments are available for low vision?
Regrettably, low vision is typically a permanent condition. Glasses, medications, and surgical interventions usually do not provide a cure for low vision; however, they may sometimes enhance vision, facilitate daily activities, or prevent further deterioration of your eyesight.
The treatment options available will vary based on the specific eye condition that has caused your low vision. Consult your doctor to find out if there are any treatments that could enhance your vision or help safeguard your remaining eyesight.
How can I optimize my remaining vision?
If you are dealing with low vision, there are strategies you can implement to maximize your sight and continue engaging in the activities you enjoy.
For those with mild vision loss, making minor adjustments can help improve your ability to see. Consider the following actions:
Utilize brighter lighting in your home or workplace
Wear sunglasses that reduce glare
Employ a magnifying lens for reading and other close-up tasks

Training on how to effectively use a magnifying device for reading
Advice on organizing your home for easier navigation
