Not everyone is born with perfect vision. Others due to unforeseen circumstances were not able to retain their perfect vision. Vision impaired disabilities pose a threat to a huge number of individuals making them a topic that should not be taken lightly. With that being said, with the help of modern age and technology, a number of optical aids have emerged providing timely and effective assistance. Let us explore the various vision impaired disabilities & how optical aids like contact lenses can help some of these people.
It should be noted that the most common visual impairment experienced by a huge number of people all over the world are the refractive errors. Refractive error in general, means that the shape of your eye does not bend light correctly which results in producing a blurred image. Refractive errors fall into different subcategories which include myopia (nearsightedness), hyperopia (farsightedness), presbyopia (loss of near vision with age), and astigmatism.
Myopia or is commonly known as nearsightedness is characterized by the condition of the eye where light focuses in front, instead of on the retina. This in turn results to distant objects becoming blurry while close objects appear normal. On the other hand, hyperopia is farsightedness is a condition of the eye where light focuses behind, instead of on, the retina.
Contact lenses can provide a wider field of vision and is proved to alleviate the problems of nearsightedness. Farsightedness requires the same approach and correction is usually achieved by the use of convex corrective lenses.
For the aging community, they are prone in developing Presbyopia. This condition is associated with aging of the eye that results in progressively worsening ability to focus clearly on close objects. Since it is considered to be a natural part of the aging process, it can be hard to avoid. A huge number of individuals were able to find relief with eye glasses Typically, the eyeglasses used have higher focusing power in the lower portion of the lens.
Last but definitely not the least of vision impaired abilities that we will be covering is Astigmatism. Astigmatism is characterized as a type of refractive error in which the eye does not focus light evenly on the retina. This in turn results to a distorted or blurred vision at all distances. Patients are given a much wider variety of option with regards to its treatment. This includes glasses, contact lenses, and surgery. Glasses are considered to be the most straightforward solution while contact lenses can provide a wider field of vision to its wearer. On the other hand, refractive surgery decreases or completely eliminates the dependency on glasses or contact lenses. Of course, the surgery option is the one that is considered to be the most expensive of the three and patients need to come prepared both mentally and physical during the procedure.
We’ve mentioned a few of the many vision impaired disabilities that we are experiencing today along with treatment solutions they can consider. It is good to hear that with the help of modern technology, the likes of optical aids have made the lives of people much easier than ever before with regards to their vision.
