Proper lighting maximizes remaining vision.
To take a picture, a camera must have an adequate light source. Likewise, the eyes must be able to process light in order to see.
- Light first passes through the cornea, which begins to focus the image.
- The lens adjusts the focus.
- A clear image is produced on a sheet of photoreceptors called the retina, located at the back of the eye.
- Photoreceptors gather visual information by absorbing light and ultimately sending signals to the brain via the optic nerve.
- The brain processes the image, allowing us to see.
When the visual process is interrupted due to aging and/or eye disease, the result is decreased visual acuity, color intensity and contrast sensitivity. As contrast sensitivity decreases, more light becomes necessary in order to see. Decreased contrast sensitivity is a normal symptom of aging but is typically intensified in the presence of other eye conditions such as macular degeneration.
We can also think about the light requirement of our eyes in terms of aging. Studies show that in order to experience the same perception of brightness, a 60 year-old adult typically requires around 15 times as much light as a 10-year-old child.
The macula is the light-sensitive area of the retina. Its job is to manufacture clear, sharp vision in the central visual field. As it breaks down, central vision deteriorates while peripheral vision remains intact.
Glaucoma is a group of eye conditions causing damage to the optic nerve due to abnormally high pressure in the eye. Early detection and treatment are key to managing the disease.
The photoreceptor cells of the retina, responsible for converting light into electrical impulses for the brain, gradually degenerate and eventually stop working.
With aging, the lens hardens and loses flexibility, no longer changing shape to focus on close-up images. Images are often blurry, and more light may be needed to see.
The most important aspect of lighting for low vision
Low vision lights, such as low vision reading lamps or low vision floor lamps, must have thoughtfully designed controls. Those with visual impairment should exert maximum control over their lighting environment to enhance functional vision and overall quality of life. Each person is different, and each may have unique sensitivities to different types of bulbs, light colors, and intensities. The goal is to find the most comfortable lighting set-up that allows you to see better while reducing eye strain.
Low vision lights should incorporate the best bulbs for low vision
LEDs are easily adjustable, remain cool to the touch, and are environmentally friendly and more economical than traditional lightbulbs. When integrated with a flexible lamp that is designed to diffuse light evenly, LEDs are the best lighting solution for low vision.
Low vision lights: Quality matters
When it comes to LEDs, not all bulbs are created equal. Bulbs from well-known, trusted brands are built-to-last and provide the most direct light while using less power. Additionally, the best low vision reading lamps and low vision floor lamps have high-quality diffusers that distribute light uniformly for optimal viewing.
Low vision reading lamps
In general, only about 12.5% of ceiling light falls on your working area. That’s why task lighting is crucial to preventing eye strain.
Low vision floor lamps
Floor lamps are versatile, providing targeted lighting for your workspace while also increasing the amount of ambient light in your room.
What are the best low vision lights? The results are in!
So, is there an LED lamp that synthesizes all key components of lighting for low vision? We’ve been on a quest to find one… a lamp that transforms living and working spaces for the visually impaired. After extensive research, testing, and talking to consumers, we’re excited to share our findings with you. Because lighting is everything!
