Recent advances in lens manufacturing techniques have made possible new high-definition eyeglass lenses that correct for higher-order aberrations. This is more the case with high prescriptions and progressive lenses. As your eye looks away from the center, the clarity of your vision diminishes. Conventional lenses provide their optimum clarity through the optical center of the lens. Things just haven’t changed that much in a very long time. After all, the most recent innovation really was back in the 1980s with the introduction of plastic lenses. You can’t really place the blame on conventional technology used to create the vast majority of eyeglass lenses and contacts. Abnormal curvature of the cornea and crystalline lens may contribute to the distortion of many higher-order aberrations. In each of us, our eyes have some degree of higher-order aberrations, but often they aren’t enough to cause issues with vision. These higher-order aberrations can cause difficulty seeing at night, glare, halos, blurring, starburst patterns, or even double vision. Higher-order aberrations are more subtle, complex refractive errors, and the technology behind traditional eyeglasses and contact lenses may not be able to correct for them. These are known as higher-order aberrations. Considering the beauty that surrounds us in Portland, seeing even better could certainly be worth it.Īll eyeglasses correct for the person’s predominant vision problem, be it nearsightedness, farsightedness, and/or astigmatism, but you could have other problems still affecting the clarity of your corrected vision.
