What are the ways to reduce the effects of myopia?
Vision is one of our five precious senses. We learn to appreciate beauty, nature, arts, people, pets, wildlife, rainbows, aurora, and other wonders of the world with our vision and other senses. Eyes are sophisticated in structure and function. The one who created eyes is a true genius. Refractive errors and visual impairment can turn human life dull. Refractive errors are common globally. The good news is that refractive errors are correctable and we can still gain the luxury of observing the wonderful world we are living in. Treatments by Doctor on Call are available for you to get better and cure any health issues you are suffering from including myopia.
Myopia is also known as nearsightedness. This means that you can only visualize things, animals, or people near you clearly but far vision will be blurry. The reasons why myopia happens are the length of the eye is too long or the refractive power of the eye is too high. The refractive power is high as a result of steep corneal curvature. As a result, the image is focused in front of the retina. A refractive device can correct this error. A refractive device with a concave surface can reduce the excessive focusing power and this will cause the image to be focussed on the retina. As a result, you will now be able to see distant objects.
Refractive errors or abnormal refraction or also called ametropia can simply be explained as the image is not focussed on the retina of the eye. Other than myopia, hyperopia and astigmatism are also refractive errors. All three conditions can be corrected with the aid of refractive devices. Hyperopia or farsightedness is a condition in which the image is focussed behind the retina as a result of short axial eye length. Another cause for hyperopia is the power of the eye is too low due to flat cornea. A refractive device with a convex surface can correct this error. The device will help you to visualize near objects. You will finally be able to read your favourite books, journal, or social posts.
Astigmatism is a condition where your vision will be blurry no matter the distance. This happens as a result of an uneven corneal surface that will cause the light to enter the eye in different planes. Different from myopia or hyperopia which can be corrected by a device with a spherical lens (concave or convex surface), astigmatism is corrected with the use of a refractive device with a cylindrical lens. Rigid or soft contact lenses which are gas-permeable can also be used to correct astigmatism.
Another condition that we should know is presbyopia. It is a non-refractive error that can affect our vision. This condition happens as a result of the eye lens to lose its accommodating power. Eyes will no longer able to focus on objects at a distance of an arm’s length or nearer. When we were young, our eyes can accommodate or increase the eye lenses curvature by contracting a muscle known as ciliary muscle. Following the natural ageing phenomenon, our eye lens loses its elasticity and no longer able to focus on objects at reading distance.
In conclusion, refractive errors can be corrected by the use of spectacles or contact lenses with particular lenses depending on the type of error. Other than that, surgical correction can also be done. The most common surgery is laser in situ keratomileuses (LASIK).
