Eye Library

Welcome to our Eye Library, our comprehensive library of vision related information. As you browse through this part of our web site, you'll find dozens of helpful articles and information that will assist you in investigating all aspects of your vision.

Children's Vision
Vision is arguably the most important of the five senses; it plays a crucial role throughout childhood and beyond. Yet many parents don't understand how vision helps their children develop appropriately. Use these articles to proactively care for your child's eyes, spot potential trouble, and maximize the opportunity for crisp, convenient and healthy vision.
Contact Lenses
Today there are more convenient and healthy contact lens choices than ever before. Whatever your vision challenge, it can probably be met with an array of specialty contact lenses for individual vision needs.
Sunglasses
Whether or not you require vision correction, sunglasses can add an element of comfort and enhanced performance to your activities, while helping you look great.
Eye Exams
Seeing clearly is just one part of your overall eye health. It’s important to have regular eye exams whether or not you wear glasses or contacts, and even if your vision is sharp. The articles below explain what problems can be spotted with an eye exam, what’s involved in a comprehensive exam, and special considerations for kids and contacts.
Vision Surgery
Tired of wearing glasses or contact lenses? Today, several surgical methods can correct your eyesight and, in most cases, give you the freedom of seeing well without corrective lenses.
Eyeglasses
The struggle between fashion and function is officially declared a tie! Never before have eyeglass frames been offered in so many stylish choices. Yet, you'll be amazed at how many options are at your fingertips to help you see well, and protect your vision.
Conditions
Eye problems can range from mild to severe; some are chronic, while others may resolve on their own, never to appear again. The articles below will give you a basic understanding of some of these problems and their implications. The cardinal rule is if your eyes don't look good, feel good or see well, you should visit your doctor.
Vision Over 40
If you are among the 85 million Baby Boomers in the United States and Canada (born between 1946 and 1964), you've probably noticed your eyes have changed. Most notably, presbyopia - the normal, age-related loss of near focusing ability - usually becomes a problem in our 40's, requiring new vision correction solutions. Learn about measures you can take to keep seeing clearly for years to come.
Vision Over 60
Just as our physical strength decreases with age, our eyes also exhibit an age-related decline in performance - particularly as we reach our 60's and beyond. Some age-related eye changes are perfectly normal, but others may signal a disease process. It's important to recognize signs and symptoms, and perhaps even more important to mitigate the effects of aging with some simple and common-sense strategies.
Sports Vision
Sports eyewear can give you the performance edge you're seeking for just about any sport. But make sure you get the eye protection you need as well. And after you're fit for the right eyewear, you might want to take your game up a notch with the same kind of vision training used by professional athletes.
Vision Insurance
It’s not true “insurance” that protects you against unexpected or overwhelming financial obligations. Vision insurance, on the other hand, is a wellness benefit designed to provide routine eye care, prescription eyewear and other vision-related services at a reduced cost. Learn about types of vision plans, and how they work.
Low Vision
Low vision is the term used to describe reduced eyesight that cannot be fully corrected with eyeglasses, contact lenses or eye surgery. The primary causes of low vision are eye diseases, but low vision also can be inherited or caused by an eye or brain injury.
Optometry Reference
AQUEOUS HUMOR
Clear fluid between the cornea and the iris. Protects the lens and nourishes the cornea. Fluid is constantly produced and drained. If the pressure of the aqueous humor is high, glaucoma can develop.

ASTIGMATISM
This is a fuzzy or blurry condition. The cornea is not perfectly shaped which causes light rays to enter the eye unevenly. Most people have some degree of astigmatism. This may be combined with Myopic or Hyperopic conditions, or solely by itself.

CATARACT
A clouding of the normally clear lens in the eye. Typically surgery is only considered when the cataracts causes enough loss of vision to interfere with daily activities.

CONJUNCTIVA
Thin, transparent membrane lining the white part of the eye. Conjuncitvitis or "pink eye" is when this membrane is inflamed.

CORNEA
Clear, dome shaped window covering the front of the eye that is over the iris and pupil. This is where laser vision correction is done.

EXTRAOCULAR MUSCLES
Eye muscles that make the eyeball move.

EYELASHES
Protect the eyes from dust and other foreign bodies. New lashes are continually growing.

EYELIDS
Two folds of skin that protect the eyes. Contain glands that create normal tears.

FARSIGHTED/HYPEROPIC
People who are farsighted are hyperopic. Distance vision is usually sharp but the near vision is not good. This is due to a shorter than normal shape of the eye.

FOVEA
Focal point of the retina, in the center of the macula, which contains only cones for sharp vision.

GLAUCOMA
A disease of the optic nerve caused by fluid pressure within the eye. If left untreated, blindness can result. Ask Dr. Bende if you are at risk for developing glaucoma.

IRIS
Colored part of the eye that lies behind the cornea and surrounds the pupil. The iris is actually a muscle that contracts to make the pupil smaller, and relaxes to make the pupil larger.

LENS
Lies right behind the pupil. The lens 'bends' light so that it can sharply focus on the retina.

MACULAR DEGENERATION
A deterioration or breakdown of the macula (small area in the retina that we use for central vision). When the macula does not function properly, central vision can be affected. Nutritional supplements may decrease the progression of macular degeneration, however, there has been no treatment that has been uniformly effective.

NEARSIGHTED/MYOPIC
This means you have difficulty with distance vision, but you have sight at near. This is due to the elongation of the eye during growth/development.

PRESBYOPIA
This is the "40+Club!. Presbyopia is due to the internal aging of the "lens" inside your eye. The ability to read items at a normal reading distance gradually diminishes and we need "help", usually by "reader cheaters", bifocal or progressive lenses or by wearing monovision or bifocal contact lenses.

PUPIL
The dark circle in the center of your eye. This is actually a hole, that your eye doctor looks through to see the back of your eye.

RETINA
Thin layer in the inside back part of the eye which contains the rods and cones.

VITREOUS HUMOR
Clear, jelly-like substance between the lens and the retina. This jelly-like substance keeps the retina in place and maintains the round shape of the eyeball.
