Metro Optics is the first in the Bronx to carry EnChroma, a state of the art lens uniquely designed to give those with color vision deficiency (commonly known as “color blindness”) the ability to see more of the broad spectrum of bright color.
Most types of color blindness occur when there is an excessive overlap of the M (green) and L (red) color cones in the eye, causing distinct hues to become indistinguishable. As a result, the number of shades a typical color-deficient person can see may be reduced by as much as 90%. The EnChroma Lens selectively filters out wavelengths of light at the precise point where the confusion or excessive overlap of color sensitivity occurs.

The most common cause of color vision deficiency is hereditary, but there are several diseases that can lead to color deficiency:
All EnChroma Lenses can be made in your prescription, with shatter-resistant Trivex to optimize clarity, lightness, and strength. Every lens offers 100% UVA and UVB protection, scratch-resistance, and anti-glare coating to optimize the visual experience.
EnChroma Cx3 Outdoor Lenses are designed to enhance color vision in outdoor in bright sunlight or partly cloudy conditions and also serve as sunglasses delivering 100% UV blocking and glare protection. EnChroma’s Cx3 Outdoor lenses deliver the maximum color enhancement effect due to the combination of bright colorful light and their lens technology. Available in Cx3 Sun for most types of Color Blindness and Cx3 Sun SP for Strong Protans.
EnChroma Cx1 Indoor Lenses are designed to be used in typical indoor lighting conditions to enhance color vision while performing activities such as school work, cooking, watching movies, browsing the web, and art projects. The Cx1 Indoor lenses best manage the effects of low light in conditions of less brightness and available color. Two custom lens types, Indoor and Indoor DT, are tuned to the special needs of either protans or deutans, to ensure the right solution. For best results, the glasses should be used with bright, full-spectrum lighting.
Children develop their color vision by the age of 6 months. It is recommended that a child receives a comprehensive eye exam (not just a vision screening) prior to entering kindergarten. During that exam, a child should also be tested for color deficiency (your child can also take the adapted Color Deficiency test here).
Though seemingly basic, the understanding of color plays a significant role in a child’s development as a student. From learning shapes (“Find the red square”) and learning math (“How many red fish are there?”) to things like identifying uniform colors in sports, etc. An understanding of color is ∙∙to most students’ learning experience.
Additional problems arise from the general lack of color deficient accessibility in educational tools. Graphs in textbooks often use colors to delineate data while increasingly visual tools, particularly those evolving from the traditional overhead projector, depend on the need for normal color vision. The lack of accessibility for color deficient students leads to an uneven playing field for those disadvantaged by color deficiency. Students tend to develop coping methods to work around their color deficiency, but such methods can slow students down and still hinder them from taking in as much knowledge as other normal sighted students.
