Age-related macular degeneration (AMD) is an age-related condition that leads to poor vision, a condition that makes visual acuity of 70/20 or worse, and visual impairment caused by eye disease cannot be corrected with eyeglasses, but for patients with macular degeneration, it may be useful to know that there are of glasses.
macular degeneration patient glasses
Macular degeneration can cause a wide range of vision problems. A patient may have no vision problem at all and then suddenly have significant impairment of central vision. Having the right type of eyeglasses may help improve vision in these people.
There are medical tests to help these people get the right type of glasses. There are several types of glasses that can help improve the vision of a patient with age-related macular degeneration, depending on the level of vision loss that the patient has reached and the stage and symptoms of the disease.
Eyeglasses for early-stage macular degeneration
Early-stage AMD involves the presence of several small or medium-sized drusen which are yellow or white spots on the retina, with minimal visual symptoms, and usually, vision loss that includes blind spots or visual abnormalities has not yet occurred at this stage of the disease.
In this stage of AMD, if a person requires corrective lenses for normal age-related vision loss from presbyopia (difficulty focusing on close-up objects) or other causes, progressive bifocal glasses may be prescribed. Alternatively, your eye doctor may suggest using two different pairs of glasses, one for reading (near vision) and one for distance vision.

protective sunglasses
An ophthalmologist may advise patients with macular degeneration to use sunglasses with grey and brown color or transition lenses to block harmful ultraviolet rays from the sun that may exacerbate macular degeneration, and the doctor may recommend the use of lenses that block 99% to 100% of UV rays harmful.
It has been found that the blue light in sunlight when it is bright worsens the condition of patients with macular degeneration, so the doctor may advise the patient to use brown lenses on those days.
polycarbonate lenses
Polycarbonate lenses can also help keep irritants away from a patient's eye, such as flying insects. When someone has an eye condition such as macular degeneration, it is important to protect the eyes from infection, especially if only one eye has good vision.
Your doctor may recommend the use of high-index polycarbonate lenses to provide your eyes with additional protection.
Middle stage macular degeneration glasses
In the middle stage of macular degeneration, the dressing in the patient's eyes is larger, their number may increase, and changes may occur in the retinal pigment epithelium (RPE), the layer of pigmented cells that lies under the retina, and these changes may lead to vision loss.
But in the middle stage, slight changes in vision occur, and they may see small grey or black spots in the middle of their field of vision, and some may struggle to adjust vision when they move from bright light to dim light, and contrast sensitivity may decrease for some, and the contrast sensitivity test measures An individual's abilities to distinguish between finer and more subtle increments of light versus dark (contrast).
yellow glasses
Yellow glasses can help improve visual contrast for middle-stage macular degeneration patients. Contrast is the difference in the intensity of light or color that makes objects recognizable.
Reduced contrast sensitivity causes the patient to see colors as faint and not as bright as they are in nature, so wearing yellow glasses at this point may correct this lack of contrast.
Also, a person with macular degeneration in the middle stage may find a problem in seeing the measurements clearly, for example, it may be difficult for him to notice changes in the height of the sidewalk, or the stairs, and this causes a lot of problems for patients as the risk of falling increases, and it may also benefit Yellow glasses correct that condition.
Lenses coated with anti-reflective material
Anti-reflective technology, available for custom macular degeneration glasses, can help to brighten the field of view, a technology that allows eyeglass lenses to avoid excessive reflection of light, allowing more light to pass from the lens into the eye, and this technology can produce brighter images of objects, than glasses normal.
Late-stage macular degeneration glasses
The last stage of the disease occurs when the patient's condition progresses to loss of vision. This stage involves leaking blood vessels that cause the deterioration of the macula. It is called the wet form of macular degeneration. This stage, or the wet form, progresses much faster than the dry form of the disease.
Symptoms of late-stage macular degeneration include loss of central vision. Objects in the middle of the line of vision may appear distorted, blurry, or may not be visible at all. Objects in the peripheral field (side field of view) are usually visible to the patient, but he or she cannot distinguish what they are.
Other symptoms may include visual distortions such as seeing straight lines that are curved or broken, gray or black spots appear in the central field of vision, and the patient may not be able to distinguish faces.
Prismatic lenses
Prismatic lenses, sometimes referred to as compact prism glasses, are used in advanced macular degeneration (including central vision loss). These lenses create aberration in light rays entering the eye. This allows light rays to avoid the muscular area that has deteriorated.
Although prismatic lenses do not eliminate the blind spots common in people with age-related macular degeneration, the lenses can help reduce the area of vision impairment, making the blind spot smaller.
Zoom glasses
Magnifying glasses can include those that magnify images, designed for distance vision, and there are also special magnifying glasses that help people with macular degeneration see things up close, for example, magnifying reading text for near vision.
Remote vision glasses are special binocular-type lenses, called "biological telescopes", which are attached to eyeglass lenses to help improve the central vision of distant objects, and the magnification level of the lenses can be adjusted according to the patient's specific needs. It is important to note that magnifying glass can help They can reduce blind spots and distortions caused by macular degeneration, but they cannot completely eliminate these vision problems.
