Reviews & Testimonials
Then I put on the glasses. Unbelievable! … It was like a peek into a world I knew existed, but had never been allowed to see.
With my Enchroma sunglasses, I can see the three distinct colors of a stoplight for the first time, and red stop signs and lit brake lights jump out with a new urgency.
The EnChroma Story
Over a period of ten+ years of focused R&D working under an NIH-sponsored small-business innovation research grant (led by Dr. Don McPherson, Ph.D), the EnChroma team approached the problem of color vision deficiency from a rigorous scientific foundation. We used the latest understandings of the genetic basis of CVD to create a sophisticated computer-based model of human color vision, and then set out to solve the general problem of determining the optimal spectral filter for any given set of conditions.
Using our patent-pending design methods we are able to design complex spectral filters to assist color vision for a wide variety of applications. Our lenses are designed to provide the maximum possible performance while also maintaining consistent and attractive color appearance and meeting necessary safety requirements for general use eyewear.
EnChroma’s mission is to leverage our lens technology platform and understanding of human color vision to create innovative eyewear products that help people see the world better.
Frequently Asked Questions
Usually, we can ship in-stock items within 1-3 business days. Prescriptions and Fit-to-Frame orders typically take 1-2 weeks to manufacture and ship.
However, order fulfillment can be subject to delays. This is especially true right now, when our orders have outstripped our fulfillment capacity. Currently, many of EnChroma’s products are made “on demand.” This means that at the time you place your order, we might not have the eyewear in stock and ready to ship. Processing time might be extended if one or more of the required components is not available.
Recently EnChroma has experienced unexpected and sudden shortages in certain lens materials as well as in some frame styles. Even items that were not listed as “backordered” at the time you placed your order may become backordered by the time your order moves through the queue. Items listed on our site as “backordered” might take even longer to ship.
In addition, all EnChroma eyewear must pass a strict quality inspection before shipping. If an item does not pass inspection, we may need to re-make it for you, which can cause further delays.
If your order is delayed for more than 30 days, we’ll email you to let you know. If you require your order by a certain date, please email email@example.com to find out if your order can arrive by the date you need.
What if I have questions or changes?
If you want to make changes to your order (including address changes and shipping changes) or if you just have questions, please send a detailed email to firstname.lastname@example.org. Include your order number in the subject line.
How do I cancel my order?
To cancel an order, please email email@example.com. Include your order number in the subject line. Prescription and Fit-to-Frame orders can be cancelled at any time before manufacturing. All other orders can be cancelled at any time before they ship.
With the EnChroma lens, colors appear brighter and more saturated. People report that their color discrimination is faster and more accurate, they are able to see more vibrant colors. They are more likely to notice objects that are differentiated against a background based on color (such as a flower against background of leaves), whereas without the lens those objects would have been overlooked.
In our user trials, people with color blindness also noticed that the EnChroma lens helped them to differentiate textures and hues within a single shade of color—for example the pattern of different shades of green on a leaf, or in a complex textures such as a hillside covered in trees may appear to be “less noisy”.
Based on our product effectiveness studies, we have found that EnChroma glasses are effective for about 80% of cases of color blindness. The results vary depending on the type and extent of color vision deficiency. You can get an estimate of your type by taking our online test at EnChroma.com/test.
The EnChroma Cx lens causes a very powerful “super-color enhancement” effect. The same “boost” that it gives to the vision of a person with color blindness can be appreciated with normal color vision as well. In addition, the lens also has a neutral color balance, which means that your sense of color accuracy is not compromised or disturbed.
We have received testimonials from some customers who have normal color vision that the glasses have beneficial effects on their mood, such as from seasonal affective disorder. While this is an interesting potential application, this particular use case has not been studied in detail yet and we do not have any official claims that can be made regarding this use.
The EnChroma Team all wears the Cx Sunglasses, even though most of us are not color deficient–and we love wearing them!
Since the first scientific recognition of color blindness in the 1790s, numerous inventions and therapies have been attempted to correct for color blindness. The first glasses for assistance with color blindness date to the 1850s and were created by James Maxwell. These glasses featured a lens having an arrangement of three differently tinted segments arranged vertically: red on the top, clear in the middle and green across the bottom. One could presumably determine the color of an object by comparing the relative brightness of its appearance in each section of the lens. Essentially it could be called a “color vision trifocal” design.
Around the time of World War II (1940s) the public awareness of color blindness increased greatly as people wanted to volunteer to fly in the air force. Flying a plane (especially at night) requires good color vision, squashing the dreams of many eager young men. Consequently, the market was flooded with “cures” for color blindness offered by unscrupulous proprietors with the promise of passing a color blindness test. These ranged from benign frauds to outright dangerous procedures such as a doctor who would actually inject snake venom into the eye. Please note that color blindness cannot be cured, and that occupational testing is required for reasons of public safety (e.g. public transport operators) and should not be circumvented.
Since the 1970s a variety of lens products have been marketed which take the form of tinted lenses applied monocularly or binocularly with different tints in each eye. The tints are usually a strong red, purple or pink color. Often the tint is put into a contact lenses, making the solution relatively discrete. While such devices can in theory provide additional spectral information, it is understood according to vision science that these devices work on the principle of binocularly rivalry (disruption of depth perception) and do not fundamentally improve color vision. Due to the low risk and possible benefit to some individuals, the FDA has permitted such devices to be sold provided that they are clearly labeled that 1) they are not a cure for color blindness and 2) have minimal therapeutic effectiveness.
EnChroma is based on a unique approach to color blindness correction: restoration of the spectral separation between cones using a narrow-band notch filter. The effect works for people with forms of anomalous trichromacy, which are the majority of cases (about 80%). The notch filter, when designed correctly, can be provided without inducing a color tint to the lens–it appears to look like an ordinary sunglass lens. Unlike conventional color-tinted lenses which distort colors–emphasizing one color at the expense of others, EnChroma lenses amplify the perception of all three primary colors simultaneously (red, green and blue). The result is a “boost” to the chromatic saturation (purity or vividness) of colors.
Technical details aside, we welcome you to examine our testimonial evidence from happy customers and consider making the investment yourself. If for any reason you are unsatisfied with the purchase, EnChroma products can be returned and refunded at any time within the 30-day trial period.
The names you see in our product catalog, “Apollo”, “Explorer”, etc, refer to the frame style. All frames we sell come with the same lens for color blindness correction, which is called the “Cx“.
Frame styles can be broadly classified according to their intended use:
- Lifestyle frames are fashionable styles including the classic aviator and wayfarer. These frames work well with low to moderate power Rx prescriptions. These frames tend to fold to nearly-flat, enabling the use of slim cases that easily fit in pockets.
- Sports frames are performance-oriented styles. They provide superior coverage–protection from stray light entering around the lens, as well as wind. They work for activities such as running, biking, etc. Specific sports such as baseball require special high-impact frames. Please note any appropriate activity restrictions. Our sports frames work well with Rx prescription lenses, including high power Rx lenses.
- Kids frames are frames made in small and extra-small sizes to fit children and youth faces. The ones we offer are sporty and work well with Rx prescription lenses.
You can also get the EnChroma lens fitted in a third-party frame of your choice.
There are many different providers of vision insurance, and their coverage & plans vary. Some insurance plans provide a general benefit that can be applied to any prescription sunglass lens. If so this benefit may be applicable to the EnChroma Cx lens which is also a type of sunglass lens intended for outdoor use.
Please contact your insurance provider to find out if EnChroma lenses are covered.
Yes. If you normally wear glasses for correction of your distance vision, then you will want to get the EnChroma lens made with your prescription.
EnChroma glasses are intended for outdoor use which generally means they are not used for near-vision correction. So, if you only wear prescription glasses for correction of near-vision (e.g. reading, office work, etc), then you may not need to order the prescription lenses with EnChroma.
Our glasses can be made with single vision prescriptions as well as bifocal and progressive corrections. You can order a frame with your prescription via our website, or via an authorized eyecare professional that carries EnChroma.
Normal Prescription range*:
Single Vision: SPH -4 to +2 CYL -6 to +6
Progressives: SPH -4 to +2 CYL -4 to +4 ADD +3
EnChroma Cx Prescription lenses are made from polycarbonate.
*Out of range prescriptions may be possible depending details of frame geometry. Please contact us for details.
Note: The EnChroma Cx Non-Prescription and Prescription lenses have the same functionality. You do not need a doctor’s prescription to buy the EnChroma Cx.
You can also get EnChroma with a “fit-over” frame called the Receptor–this can be worn over your regular glasses (see below).
