There are several different types of vision which could be causing problems with your eyesight. If you notice any distortions in your vision, including blurriness, book an appointment with your optician who can complete an eye examination and recommend treatment options with you.

Emmetropia

If your vision is very clear with no refractive error or de-focus, you have emmetropia. This means you have the ideal distance vision with no visual defects. Your vision is clear and focused and therefore does not require lenses.

Shortsighted

When objects up close look visibly clear but objects in the distance look blurred, this can mean that you are shortsighted. This can be corrected using glasses, contact lenses, lens implants or LASIK, just visit your optician for an examination and advice.

 

Shortsightedness usually occurs because your cornea is too steep or your eye is too long and therefore light rays focus in front of your retina, instead of on your retina.

Longsighted

If you are longsighted it means that you can see objects in the distance clearly, while close up objects appear blurred. Again, this can be corrected using glasses, contact lens implants or LASIK.

Longsightedness is due to your cornea being too flat or your eye being short and light rays will focus behind your retina.

Astigmatism

Astigmatism occurs when there is a problem with the shape of your eye’s cornea. This means that the lens of your eye or your cornea has an irregular curve. As a result, this can affect how light passes or refracts to your retina and you may notice that your vision is distorted or blurred.

Presbyopia

People aged between 40 to 50 years old may begin to notice that they are struggling with their vision while reading. As your eye ages, muscles can begin to struggle as your eye lens becomes harder. Therefore, if you are struggling with your reading vision, visit your optician for recommendations on reading glasses, contacts and lens implants and ask if LASIK can be an option.

20/20 Vision

You may have wondered what 20/20 vision is, or even 6/6 vision. 20/20 vision is used to describe the clarity or sharpness of someone’s vision, which is considered to be normal visual acuity. Whereas, if you have 20/100 vision, it means that you need to be 20 feet from an object to see it just as clearly as how someone with normal vision would see it from 100 feet.

6/6 vision or anything similar is the same concept. However, while 20/20 vision is the more common term, in the UK we refer to 20/20 vision as 6/6 vision.
