Nearsightedness (Myopia) causes, symptoms and treatment

Nearsightedness is an eye condition that makes you see near objects
clearly, while far objects seem blurry and hazy because the light coming
to the eye is not focused correctly. It occurs more often to children and
teenagers and may appear gradually or suddenly.


Causes
Eyes have two main parts that work together to bend the light onto the
retina, cornea and lens; In Myopia cases eyeball usually is too long from
front to back, or cornea is too curved so that light coming to the eye
focuses in front of the retina instead of on it, which makes far objects
look hazy.
Genetic factors and family eyes medical history may increase the
probability of having nearsightedness.


Symptoms
● Faraway objects seem very blurry and hazy.
● Headaches because of eye strain.
● Difficulty in vision while driving, especially at night.
● Feeling the urge to cover one of the eyes with hands to see clearly.
● Setting close to TV screens to see better.
● Rubbing eyes with hands frequently.
● Blinking too much more than usual.


Treatment
Myopia cannot be totally cured, but vision can be improved and
enhanced to normal by simple solutions.
Most people go for using glasses or contact lenses to correctly focus
light to be on the retina instead of in front of it, which is a safe and cheap
solution.
Others may go for surgeries, there are different surgeries such as using
a laser to cut a flap through the top of the cornea or a new lens in the
eye replacing the natural one, these solutions are usually more
expensive than traditional treatments.
Finally, regular eye checkups since childhood would prevent Myopia
from getting worse

Farsightedness (Hyperopia) causes, symptoms and treatment

Farsightedness is an eye condition that makes you see far objects veryclearly while having trouble seeing close objects as they seem blurry.


Causes
Farsightedness eyes don’t bend light correctly, they under-focus the light and form an incomplete image on the retina, which may happen if the eyeball is too short, the cornea is too flat or the lens is getting older. Hyperopia is usually inherited; if your parents have it, you are more likely to get it as well.


Symptoms
Although some of farsighted people may not feel any problem, if the eye muscles are working harder to see better, they may develop some symptoms such as:
● Blurry and hazy vision, especially when looking at close objects.
● Eyestrain.
● Dull pain in the eye.
● Difficulty in reading.
● Headaches.
● Squinting.


Treatment
Hyperopia does not go away with time, the ophthalmologist most probably will suggest solutions to improve vision quality such as: eyeglasses, eye contacts or surgery. Lenses in eyeglasses are a simple solution to correct farsightedness, as they change the way the light is focused on the retina. Contact lenses work almost the same way the eyeglasses do, yet are small and sit light directly on the surface of the eyeball. Both eyeglasses and contact lenses are totally safe and very convenient.
Farsightedness may also be treated by refractive surgery using laser to change the shape of cornea to adjust eyes’ ability to focus and enhance farsightedness. Regular checkups help to prevent Hyperopia from getting worse and are really important to adjust the lenses measurements over time

Astigmatism causes, symptoms and treatment

Astigmatism is a very common eye condition that causes blurry vision at any distance, most people have it on some level and it usually happens because of irregular curve in the cornea.


Causes
Normal eyes usually have round shape so when light enters, it refracts evenly and focuses on the retina at the back of the eye which makes us see clearly. Eyes with Corneal Astigmatism are usually shaped more like an egg or a back of a spoon; when light enters, it refracts unevenly in one direction
more than the other, so it does not focus correctly on the retina; that makes
only part of the object in focus which leads to blurry and wavy vision at any
distance.
There is another type of Astigmatism, Lenticular Astigmatism, in which the
lens imperfections prevent images from reaching the retina correctly.
People may have one type of Astigmatism or may have them both.
Astigmatism usually comes along with Nearsightedness and
Farsightedness and most probably is inherited in the family eye medical
history.


Symptoms
Astigmatism symptoms may look like other eyes conditions symptoms, only
an eye specialist can diagnose it right. These symptoms are:
● Blurry and wavy vision at any distance.
● Fatigue.
● Headaches.
● Squinting to see better.
● Eye strain.
● Difficulty seeing while driving especially at night.


Treatment
Eyeglasses and contact lenses are usually the most common treatment for
astigmatism as they are very safe and convenient, and people with slight
Astigmatism may not even need them if they don’t have another eye
condition.
Some people may go for surgery correcting some types of Astigmatism
using laser, as it provides them a long term solution depending on the
severity
