This yellowing reduces the sensitivity to blue light, which is necessary for vividness, and conversely, increases sensitivity to bright yellow light. Symptoms such as "blindness due to glare," "blurred vision," "dimness in the field of vision," and "scenery not looking beautiful" are often caused by this yellowing. NeoContrast lenses selectively cut only the yellow light (585nm) that causes the most glare! Despite not being a dark lens color, they significantly reduce glare, ensuring a bright and clear field of vision. Furthermore, the photochromic lenses darken under UV light, further reducing glare!
