Myopia-link

Myopia, more commonly known as nearsightedness, is slowly becoming more and more widespread across the globe. Such is the growth curve of this condition, that by 2050, 5 billion people around the world are predicted to be myopic, where the number for highly myopic people is estimated to be around 1 billion. Myopic vision correction is possible with regular eye tests and power corrections. Awareness of it can keep you and your dear ones safe from the vision related implications it carries:

What is Myopia? blog3

Also known as nearsightedness, Myopia is the most common form of refractive disorder of the eye. This condition results in the elongation of the eyeball, thus displacing the focal point of the cornea and the lens of the eye. Ideally, light rays entering the eyeball through the lens, should be refracted to focus directly on the retina, to create the perfect image. But when the eyeball gets elongated, the distance between the cornea and the retina increases, which leads to the light rays being focused on a point in front of the retina. Sometimes, the light fails to reach the retina surface because of extra curvature of the cornea. In both these cases, light rays fail to focus on the retina, causing faraway objects to appear blurry.

Many ophthalmologists opine that eye fatigue from digital device usage, other prolonged near vision tasks, coupled with a genetic predisposition are the common causes.

Symptoms of Myopia 2

People with nearsightedness or Myopia generally have trouble viewing far off objects. Reading road signs get difficult, whereas closer tasks like reading, computer usage etc, are still doable. Squinting, eye strain and headaches are also symptoms of myopia. Eye fatigue while driving or while playing sports are also telltale signals that one should get the eyes tested. If you have Myopic vision, in your eye test prescription card, the first number ("sphere") will be preceded by a minus sign (-), the higher the number, the more myopic your vision.

High Myopia and its consequences blog2

People whose eye power falls under the spectrum of high myopia have a lot to consider regarding their vision and the health of their eyes. Because of abnormal elongation of their eyeballs, their eyes are more susceptible to certain conditions.

High myopia can accelerate the changes in the vitreous humour of the eye, which normally occurs with ageing at a much later stage in life.

High myopia can also lead to retinal detachment, where your retina can get overstretched and tear. This tear or hole can cause the fluid in your eye to leak out and result in the detachment of the retina from the back of your eye.

Both these conditions can result in symptoms like – flashing lights, abnormal floater activity in your eyes, and a curtain effect coming up or down on your eyes.

Dealing With Myopia :  

Myopia is a measurable refractive error of the eye, which can have degrees of severity. It can be corrected with eye glasses, contact lenses, or refractive surgery. A good choice of lenses for your spectacles for myopic eyesight include high index lenses (they are thin and light) with anti reflective coating. If you have high exposure to the sun, consider photochromatic lenses.

At Vision Express we care for your eyes, the certified optometrists conduct a comprehensive, 6-step eye test to determine the most accurate power for your vision correction. The silicone hydrogel lenses of Vision Express are there if you choose contact lens as your option. Mostly, Myopia is simply a minor inconvenience in daily life activities. But sometimes the condition can be progressive and severe enough to be considered as a degenerative condition. So stay alert and get your regular eye tests.
