Refuge to unveil scope for colorblind visitors

Florida’s J.N. “Ding” Darling National Wildlife Refuge on Sanibel Island will be the first national wildlife refuge to expand its accessibility initiatives to include a spotting scope for colorblind visitors. The scope, specially engineered by SeeCoast Manufacturing with EnChroma’s patented lens technology for colorblindness, will be unveiled at the Wildlife Drive observation tower on Wednesday, August 4. EnChroma eyeglasses will also be permanently available at the refuge for guests with color vision deficiency to borrow during visits.

August 4 marks the newly declared Great American Outdoors Day in honor of the signing of the Great American Outdoors Act in August 2020. Admission to the refuge’s Wildlife Drive will be free to all that day. Refuge staff will unveil its new colorblind scope at 10 a.m.; the public is invited to attend.

“It seems fitting to honor an act that provides funding for facilities and infrastructure at national wildlife refuges and other federal public lands by broadening this refuge’s accessibility to a new audience of visitors with color vision challenges,” said supervisory refuge ranger Toni Westland. “The new scope and EnChroma glasses will help colorblind people experience our natural, colorful beauty and wildlife as a normal-vision person would, plus the scope is wheelchair-accessible. It’s a very exciting step for people with vision and mobility limitations.

“We will have colorblind people on hand at the unveiling to try the scope and EnChroma glasses for the first time and share their reactions,” said Westland, who led the project to bring the scope and glasses to the refuge. “This follows on the heels of numerous accommodations — such as the observation tower’s accessible ramp, the lift at the Visitor & Education Center, and wheelchair accessibility on Tarpon Bay Explorers tram tours – to make visitor services at the refuge available to the greater public. EnChroma’s donation of corrective eyeglasses will allow colorblind children and adults eventually to check them out for use on Wildlife Drive.”

Limited color spectrum

One in 12 men (8 percent) and 1 in 200 women (0.5 percent) are color-vision challenged; 13 million in the United States alone are born with the genetic deficiency. That means that out of the refuge’s nearly 1 million visitors annually, statistically, an estimated 42,500 are colorblind.


While people with normal color vision see more than a million hues and shades of color, those with color vision deficiency only see an estimated 10 percent of color variations. As a result, their color spectrum is more limited, and their world view is duller and muted, while certain colors are difficult to differentiate from each other.

“Ding” Darling is at the forefront of public lands and cities that are bringing this new technology to change the outdoor experience for colorblind people. The refuge’s is the first such public viewing scope in Florida and on any federal lands.

Fewer than 20 other such scopes are available currently to the public throughout the nation. Twelve are in parks and overlooks in Tennessee, put in place by the state’s Department of Tourism, and others are at Amicalola Falls State Park in Dawsonville, Georgia; near the base of Mount Hood in Sandy, Oregon; and at Life Cancer Center in Fresno, California. A spokesperson for Enchroma says more will be announced soon.
