Over the years the eyes are subject to small changes that affect a person's vision and clearly they can see objects close to them as well as things in the distance. Typically there are three distinct types of vision correction that are needed as a person begins to age. Single vision lenses, bifocals and trifocals are worn by individuals that have lost the ability to focus their eyesight at different distances or ranges. By meeting with an eye doctor Orange County residents can learn more about the differ options available to them for correcting their limited vision and bringing the world back into focus.
For some children the need to wear corrective lenses is something that they will have prescribed for them from an early age. Although many people do not need glasses or contact lenses until they are in their early 20's each set of eyes are different and a child may require a prescription to correct a number of different ailments associated with their ability to see.
For the most part the two main types of problems dealing with eyesight are myopia (nearsightedness) and presbyopia (far sightedness). Each requiring a different curvature to the lenses that are designed to balance the refracted light that enters the pupil and is interpreted by the optic nerve, a set of eyeglass will have either a concave or a convex curve ground into them by an optical lab.
In addition to myopia and presbyopia the eyes can be affected by diseases that strain or limit a person's vision even further. Glaucoma, cataracts and macular degeneration are common illnesses that need to be treated by an eye doctor. Orange County residents that are experiencing a blurring in their vision as they get older may be going through the normal changes in their eyesight that can occur at anytime, but which have been mostly noticed as an individual reaches their 20's, 40's and 60's.
Every 20 years the eyes seem to lose a little more of the muscle tissue that allows the optic nerve to focus at different lengths of vision. While ageing is the cause of the changes an eye doctor can correct the distances so that a person can see to read things up close and have the ability to see things that are at arm's length and further out into the distance. For the majority of the population the need to have some sort of vision correction takes them to the offices of an eye doctor who can identify the correction and prescribe glasses, contact lenses or surgeries that can restore an individual's eyesight to a clear 20/20 acuity.
