If you have been worried about how to protect your eyesight, it is important you first have a good knowledge of the different types of vision. This way, you will then know how to fully protect your vision. Listed below are various types of vision. They are:
- Normal Vision: Otherwise known as “20/20”, with this type of sight, you are able to clearly see objects up to 20 feet away from you. This however, does not mean that a person with “20/20” vision has a perfect vision since there are other components that come together to make perfect vision and include eye coordination, peripheral awareness, focusing ability, depth perception, color vision, and others.
- Far Sighted Vision: Also known medically as hyperopia, it is a condition where the person is able to clearly see objects in the distance while the closer objects seem very blurry. To better help you understand how you can protect your eyesight when you are far-sighted, it would help to know that light rays are unable to focus clearly on your retina because the eyeball is too short. This is the reason why you can see far clearly but not close. In order to improve such vision, refractive surgery or use of corrective lenses is recommended, depending mostly on choice and age.
- Nearsighted Vision: Otherwise known as myopia, this is a condition where you are able to see closer objects clearly but when it comes to objects in the distance, they become blurry. In such situation, the options open to the sufferer is either a refractive surgery or use of corrective lenses. In carrying out refractive surgery, the curvature of the cornea is reshaped through various procedures. On the other hand, the corrective lenses could come in the form of contact lenses and eyeglasses.
- Blurriness By Age: A good number of people aged 40 and above find it difficult to read magazines and newspapers without holding them at arm’s length. This type of eye defect, also known as presbyopia, is caused mostly by age and even though the process starts at an early age, it goes unnoticed until the person gets of age. That is when the changes become noticeable. Just like farsighted and nearsighted visions, this defect can be corrected through refractive surgery and use of corrective lenses.
- Astigmatic Vision: This is a condition in which the person is not able to achieve clear focus because the eye’s cornea is oval, instead of being round. It usually comes with a concurrent condition – either nearsightedness or farsightedness. In order to correct it, refractive surgery is carried out. It can also be corrected with the use of corrective lenses. The strange thing is that in the case of astigmatism, if you wish to treat and protect your eyesight through the use of lenses, you will need to continue wearing the lenses but not frequently. Discontinuing this treatment will make the eyes to return to their once oval shape again.
What is your vision type? If you are not sure, then it is time for you to book a visit to a qualified optometrist and pass through eye examinations and determine your vision type. With this, you will be in a better position to improve your eyesight and at the same time, protect it.
