Is the world starting to look a little blurry around the edges? If so then you might be affected by a refractive error.
What Is Refractive Error?
A type of vision impairment that occurs when the eye is unable to focus clearly on anything thereby making your vision blurry to varying degrees depending on how far your eyes have deteriorated in a period of time. The three most common visual impairment errors in Dubai are; Myopia, Hyperopia, Astigmatism and Presbyopia. Myopia is more commonly referred to as ‘nearsightedness’ and is associated with those who are unable to see objects in the distance. Hyperopia also known as ‘farsightedness’ is the exact opposite; it refers to someone who can see far but has trouble focusing on things at close proximity. Astigmatism on the other hand is a whole different ball-game where the affected suffers distorted vision as a result of an irregularly curved cornea. The cornea is the clear covering of the eyeball. Presbyopia is a refractive error that is associated more with the elderly population and leads to difficulty in reading or seeing at arms length.

Refractive Error Treatment
Even though refractive errors in Dubai and around the world are taken lightly by most it is important for you to know that such ailments cannot be prevented if you are susceptible to it. The leading cause of refractive errors in Dubai is being genetically disposed to the disease. Such visual impairment errors in Dubai can be diagnosed via an eye exam performed by an optician. Refractive errors are treated or controlled with corrective eyewear such as glasses, contact lenses or any form of refractive surgery. The world health organization has estimated that over 153 million people excluding those who suffer from Presbyopia live with visual impairments on a daily basis.
A refractive error is diagnosed through a comprehensive eye examination consisting of refraction and visual acuity test. Your family history and other medical conditions will also be taken into consideration during the diagnosing process. Given below are the testing methods in detail for your reference.
Visual acuity test – The test will assess how well you can see at a standard distance. An eye chart positioned 20 feet away will be presented for you to read the letters with increasingly smaller sizes. The reading may take place in both eyes and covering one eye as well. To check your close-up vision, a few lines from a preprinted card will be given. If you are able to see and read all the letters, you are considered to have 20/20 vision.
Corneal Topography – This test usually takes place if your eye doctor notices an unusualness about your cornea. You will be asked to keep your chin and head into a specialized optical instrument and to look at the illuminated displayed pattern displayed on the screen. A digital camera located in the center will capture the reflection, and the information will provide a 3D image of your eye. The completion of the test will provide you with the refractive error for you to have, and the prescription can be used to get the corrective lenses for your glasses or contacts.
Some symptoms of refractive errors are; glazed vision, double vision, having to squint to see clearly, headaches, haloed vision around bright lights and having to strain your eyes to see. So if you feel as though you might be a victim of a refractive error then make haste to your optician and undergo a very basic and convenient eye examination where you will be required to read out numbers or letters up close and at a distance coupled with an eye-gizmo that focuses your sight on objects in a computer screen in order to determine the extent of the disease so that you can determine the correct course of action for you to go about treating your visual impairments without further ado.
Treatments For Refractive errors
Refractive errors can be treated with eyeglasses, contact lenses, or surgical procedures.
Eyeglasses – Eyeglasses work by bending the light rays similar to the natural lens and cornea in your eye. The lens will be adjusted according to the different errors caused by problems with the cornea, lens, or shape of the eye. Reading glasses are used to treat presbyopia conditions or to read the things that are close. Single vision prescription lenses are used to correct either distant vision or near vision. For those with both errors can choose multifocal lenses to use the pair of eyeglasses for all purposes.
Contact lenses – These are the thin lenses that can place your cornea to correct your refractive errors and benefit from a clear vision. If you are worried about appearance or finding it difficult to wear glasses, contact lenses are a safe and effective way to clear your eyesight. The lenses are available for daily wear for around 8-12 hours a day, and extended wear lenses can be used overnights. The lenses need to be cleaned with a solution and taken good care of to avoid eye infections or allergies.
Eye surgeries – The most common type of refractive eye errors are LASIK and Femto-LASIK treatments that can correct your vision by altering the shape of your cornea. LASIK uses laser light to change the cornea and fix nearsightedness, farsightedness, and astigmatism conditions. However, a comprehensive eye exam is required to check whether you are the right candidate to go through this process. LASIK treatments will benefit people to see well enough without having to wear glasses or contacts.
