what is Vision Impairment?

Vision Impairment

Vision impairment is one of the most common eye disorders in the world today. Globally, at least two.2 billion individuals have some sort of near or far vision impairment. In at least one billion or about sixty percent of cases, vision impairment would have been easily preventable or has not been addressed. While it may be impossible to prevent all impairments, many individuals can prevent vision loss and vision problems by taking simple steps that prevent loss and problems. These steps, when followed, not only reduce loss but also improve and prolongs an individual’s visual abilities and in some cases, can even cure an individual’s vision impairments.


Loss of sight

is often caused by damage to the eye or related to aging. Age-related eye diseases include age-related macular degeneration, cataract, glaucoma, and loss of peripheral vision. As a result of the damage to the eyes caused by these diseases, loss of visual acuity and in some cases total blindness occurs. Other causes of vision impairment and loss of visual field include stress, trauma, infections, and medications. Individuals who experience frequent headaches, double vision, or tunnel vision are often candidates for vision loss and eye problems. Some individuals experience a type of “tunnel vision” where objects appear as dots on a field that extends from the central vision to the peripheral vision.


Many individuals with eye disorders

such as myopia, hypermetropia, presbyopia, astigmatism, and presbyopia can improve their vision impairment and visual field through the use of corrective eyewear such as monocular sunglasses, toric contact lenses, bifocal glasses, and multifocal sunglasses. Individuals with these types of eye conditions can correct their vision impairment and visual field through the use of corrective eyewear. However, monocular sunglasses are not appropriate for individuals with presbyopia or hypermetropia because these sunglasses will not provide adequate correction for your eye conditions. Individuals who suffer from myopia will not improve their vision impairment and visual field through the use of monocular sunglasses. If you suffer from myopia, you should not wear monocular sunglasses because these sunglasses will not help you see objects better. You should also avoid wearing bifocal glasses if you suffer from presbyopia because the distance your gaze reaches while wearing these glasses increases your risk of having an eye infection.


Some eye care services doctors recommend

the use of multipurpose contact lenses for individuals with diabetic retinopathy. These contact lenses help to improve the vision impairment and visual field of individuals who suffer from diabetic retinopathy. These contacts work well for people with dry eye syndrome but may not be as effective for individuals with myopia or hypermetropia. Dry eye syndrome is a condition that can cause the eye to produce less lubrication, which in turn impairs the ability of the eye to heal. Individuals with diabetic retinopathy are also more prone to developing presbyopia, but there is no established treatment for this vision impairment.


Individuals with myopia or hypermetropia

should avoid standing too close to lights when driving. In addition, individuals with either eye condition should avoid heavy glazing procedures such as home films, reading glasses, or computer monitor screens. If you spend a lot of time reading print materials at work, you should try to reduce the amount of time you spend near the computer by using desktop publishing programs, which are often better than computer screens. If you drive, you should pay more attention to the distance you keep between your car and the lights on the road because this could mean that you are suffering from vision impairment that could cause you to have a distant vision impairment or near vision impairment.


There are two categories of vision impairments

that include near and distant vision impairment. Individuals who have a distant vision impairment will need to wear sunglasses or a bifocal contact lens while they are driving, but they will not need to wear reading glasses or a corrective laser to correct their problem. Individuals with a near vision impairment will have to wear reading glasses or a bifocal contact lens while they are driving and will also need to wear sunglasses or a bifocal contact lens if they spend a lot of time driving or reading print materials at work. Individuals with a combination of both impairments will require the services of a licensed optometrist or ophthalmologist to help them see better.
