Age-Related Macular Degeneration
Age-related macular degeneration (AMD) is the leading cause of vision loss among people age 50 and older, and it is most likely to occur in people over the age of 60.
With AMD, the macula is damaged over time. The macula is a small point near the center of the retina that is responsible for creating sharp, central vision needed for looking at objects straight ahead.
The progression of AMD is different for everyone. Some people may not experience much vision loss for a long time, while others lose all vision in one or both eyes.
As AMD progresses, a blurred spot in your central field of vision grows larger. This can cause blank spots in your vision or cause objects to not appear as bright as they used to be. As the disease gets worse, people experience more difficulty with daily activities, such as driving, reading, writing, and recognizing faces.
One of the technologies developed to help people experiencing AMD is macular degeneration glasses. Regular glasses may have been helpful in the past, but as AMD progresses, they become less effective at providing clear vision. Macular degeneration glasses have been specifically designed to help people with low vision see clearer and have smaller blind spots.
Types of Glasses for Macular Degeneration
If you would like glasses to relieve symptoms caused by advanced macular degeneration, it is important to find special macular degeneration glasses. Regular glasses lenses are only able to focus light onto the damaged cells in the macula. The picture will still be blurred because no accommodation has been made for the damaged macula.
With macular degeneration sunglasses, two special lenses are used to provide better magnification and make blind spots appear smaller.
Types of glasses for macular degeneration include:
- Low vision glasses. Important for helping AMD, these glasses provide high-powered magnification to reduce the size of blind spots. Different lenses can be used with special tints and coatings to improve the transmission of light, reduce glare, and improve the ability to see contrasts. These glasses are best suited for reading, writing, working on the computer, playing cards and other games, and doing any close-up activities.
- Distance vision glasses. Special binoculars or small telescopes can be mounted onto glasses to improve central vision of items far away. These are best suited for watching TV, going to the theater, watching a sports game, and looking at nature or anything far away.
Who Are the Glasses Right For?
Finding the right type of macular degeneration glasses for yourself depends greatly on the level of AMD you have. To begin, many people with AMD benefit greatly from getting an updated measurement of their refraction to determine which power of lens will benefit them the most. Once you have a current picture of your AMD, you can look for the glasses that will help you the most.
The varying stages of AMD call for different glasses.
- Early AMD: Someone with early AMD may have very little vision impairment. Progressive bifocals or having separate pairs of regular eye glasses to assist with near and distance vision may be enough.
- Early to Moderate AMD: People experiencing drusen, or white spots on the retina caused by AMD, can have difficulty seeing in a dark room when they first come inside and have decreased sensitivity to seeing contrasts. Yellow-tinted glasses can help someone with these challenges distinguish between colors more easily.
- Advanced AMD: People with advanced AMD are likely to benefit the most from special macular degeneration glasses, like the ones explained above. High-magnifying and built-in prisms in specialized glasses help the two eyes to work together to assist with near vision, while small mounted telescopes can improve distance vision.
If you are not sure which stage of AMD you may have, speak with your optometrist. They can provide a thorough consultation with comprehensive testing to make an accurate diagnosis of your AMD and determine the most appropriate type of glasses for you.
Macular Degeneration Glasses Brands
In order to improve vision for people with AMD, a number of companies have developed high-tech products. Products designed to help low-vision include magnifiers for macular degeneration (handheld magnifiers, desktop magnifiers, video magnifiers), apps, and wearable glasses. As one of the most practical aids available, wearable glasses are a popular, although expensive, visual correction device.
Brands of AMD glasses include:
- The Jordy Portable System. With a built-in HD autofocus camera, HDMI input for watching TV, and the ability to work as a desktop video magnifier, these are a popular version of AMD glasses. They cost $3,000 to $4,000, however, and a doctor’s prescription is required.
- The Eschenbach Max TV Glasses. Special binoculars are mounted onto the lenses of these glasses to help with distance vision associated with watching TV, sports events, going to concerts, and exploring outside. Available on Amazon, these glasses cost under $200 and can be customized with your proper prescription.
- eSight: Electronic glasses developed by eSight are smart glasses for people who are legally blind. They can be life-changing for people with extreme vision impairments, but also cost close to $10,000 a pair.
- NuEyes: This company provides lightweight electronic wearable smart glasses for people with visual impairments. With prices ranging from $1,500 to $3,000, they are a slightly more affordable option.
Speak With Your Doctor About Macular Degeneration Glasses
If you are interested in getting a pair of macular degeneration glasses in 2020, it is important to speak with an optometrist who specializes in low vision. Low vision specialists are well informed about the options available for enhancing your near and distance vision. They can assess your current stage of AMD and write a prescription for lenses that will give you the greatest level of vision improvements.

Safety of laser pico projectors
Pico projectors are small video projectors, often battery powered. The light source can use light-emitting diodes (LED) or laser diodes. The remainder of this discussion will be about laser pico projectors.
The MicroVision ShowWX+ laser pico projector is about the size of an iPhone
The laser light emitted from a pico projector is very different than light from a laser pointer. It is much more divergent, since the goal is to display a relatively large image -- not a dot.
Regulatory implications
Any laws and regulations that apply to “lasers” should be careful to define how the term applies to high-divergence laser sources such as pico projectors. For example, a law trying to control laser pointer and handheld laser misuse should exclude laser-based pico projectors. Some sample wording is discussed on the page If you are writing a laser law.
Safety implications
Responsible manufacturers take the safety of laser pico projectors seriously. The unit pictured above is Class 2. This is the same as laser pointers below 5 mW (the U.S. legal limit for selling a laser as a pointer).
Class 2 lasers are considered safe due to a person’s blinking, moving or looking away from a bright light. The laser will not cause harm in the time it takes to avoid the beam. However, intentional staring can be unsafe, so use by minors should be monitored -- just as with laser pointers.

Case study of a possible laser picoprojector eye injury
In August 2017, a person wrote to LaserPointerSafety.com regarding a possible eye injury from a laser pico projector.

The person had purchased a $400 laser pico projector, from a major, world-famous manufacturer. These are the specifications:
Class 3R
Wavelength: 445-639nm
Beam Divergence: 4.5mrad.
Pulse Frequency: 60hz
Output: 206mW

In June 2017 he began to have problems in his right eye: “Street lights and car headlights started to appear unusually blurred and bloomy at night, sharpness of objects at a distance in the daytime dropped noticeably from my normal prescription (which itself had barely changed at all over the last 20 years prior to this), and it began to feel like there was constantly a foreign object in that eye.”
A visit to an optometrist failed to find a foreign object, and other tests were inconclusive.
This is when he wrote to LaserPointerSafety.com. He wanted to know if looking at the laser pico projector light for so long could have had an effect. (Although he did not have direct laser light in his eye, there are situations where looking at diffuse ultraviolet or blue light can cause photochemical damage to the cornea and lens, similar to sunburn.)
We wrote to some top laser safety experts. They agreed that the laser light exposure did not seem hazardous, and the cause likely lay elsewhere:
Expert 1:
His description of his viewing conditions of diffuse reflections does not sound to me potentially hazardous — particularly if the projected image was comfortable to view. His description sounds like it would be more plausible to suspect and age-related conditions; but, you do not indicate his age. I have encountered many a case of an age-related change being wrongly attributed to light exposure from a copy machine, photo light sources, etc.
Expert 2:
My thoughts were the same,… potentially age-related issues. I was surprised how quickly this became an issue with my own eyes.
Expert 3:

Other causes of these vision changes should be investigated. Medications and health should be considered. Blurry vision and bloody lights at night could be caused by lens or retina problems. The pain sounds more like a corneal problem, foreign body or recurrent corneal erosion or possibly anterior uveitis.
I would like to know his visual acuity, Amsler grid results, OCT, and maybe fluorescein angiography. If he is relatively young to middle aged, central chorioretinopathy (CSC) should be considered. That is a disease in which a serous detachment of the neurosensory retina occurs over an area of leakage from the choriocapillaris through the retinal pigment epithelium (RPE). Other causes for RPE leaks, such as choroidal neovascularization, inflammation, or tumors, should be ruled out to make the diagnosis.
The causes of CSC are not fully understood. It is thought that any systemic exposure to a corticosteroid drug can bring about or worsen CSC. Corticosteroids are found in allergy nose sprays and anti-inflammatory skin creams available over the counter, and are often prescribed to treat a variety of medical conditions.
Age-related macular degeneration is more likely in older patients. While that develops slowly symptoms can occur with over a short time. If associated with fluid the prognosis is worse.
I agree with [Expert 1] that chronic long term diffuse reflection at these wavelengths would not be expected to cause photochemical damage to the retina.
Sudden blurry vision can have many etiologies.
An extensive exam is certainly indicated.
