How can we control glare with contact lenses?

• A. Prismatic coating and anti-reflective
• B. Double-gradient tint
• C. Scratch resistance coating
• D. Aperture control, solid tint

Answer: (D)

Glare control with contact lenses works by limiting how much light reaches the eye. A solid tint lowers the overall brightness entering the eye, which reduces glare and discomfort in bright environments while preserving more natural vision than strategies that try to change reflections or coatings. The idea of aperture control fits here in the sense that the lens is effectively letting in less light, similar to narrowing an optical aperture. Other approaches steer toward features that aren’t typically used in contacts for glare reduction. A prismatic coating and anti-reflective treatment are more common on eyeglasses and aren’t standard or practical on soft contact lenses. A double-gradient tint provides uneven shading, which can distort color perception and vision in varied lighting. Scratch resistance coatings address durability, not glare.
