Refractive ametropias, where the eye has a normal axial length, but objects.
Optical engineering and biology are interwoven to produce the most sophisticated imaging system known. The human visual system functions over a broad range of conditions, adapts to its surroundings and is capable of quickly processing complex visual information at enviable speeds. Many of the great names of optical physics such as Newton, Maxwell, Young, Helmholtz, and Alvarez have all made significant contributions to the field of visual optics. This book assembles much of the anatomy, physiology, and functioning of the eye, as well as the engineering and design of a wide assortment of tools for measuring, photographing and characterizing properties of the surfaces and structures of the eye. Finally, descriptions of our attempts to correct vision, reverse the aging process, and improve on Mother Nature are given. I would like to express my gratitude to several colleagues for their help with this book. This book is dedicated to my wonderful wife Diana, my son Max, and my daughter Marie.
Often, these lenses require additional measurements to personalize the lens for you.
Disposable contact lenses — Contact lenses designed to be thrown away daily, weekly, bi-weekly, monthly or quarterly. Eligible — Approved to receive benefits. High index — This super thin lens is best for those with a strong prescription. They are designed to bend light more efficiently and allow light to travel faster through them.
Your eye doctor may want you to use a high-index lens depending on your prescription and the frame you choose. This technology involves bonding one lens to the center of another to reach the correct power. Network In-network — The group of professional providers that we contract with to provide vision care for our members. Our network includes opticians, credentialed optometrists, and ophthalmologists who can provide services, eyeglasses and contacts covered under the plan.
Out-of-network OON provider — A professional provider who is not in our network of approved, credentialed providers. Photochromic lenses — Sometimes also referred to as variable tint or light-adaptive lenses, these lenses change color based on different levels of light.
They continuously adapt to changing light conditions and are virtually clear indoors and at night. Plus, they also block UV rays and filter blue light.
Polarized lenses — A common lens add-on that cuts down on glare from the sun. Ideal for driving or outdoor activities, especially water and snow sports. Polycarbonate — A commonly-used lighter, thinner material that helps your lenses resist impact.
Progressive lenses — Bifocal or trifocal lenses with no lines; available in both standard and premium brands. Provider — An optician, optometrist or ophthalmologist who offers eye care or eyewear to EyeMed members.
Scratch-resistant coating — A common lens coating that helps reduce lens scratches. Single vision lenses — Lenses prescribed for people who only need help seeing either far away or up close not both.
