MYOPIA / Nearsightedness / Shortsightedness


It is wide spread defect that characterized by difficulties to see far distant subjects; it may appear blurry. Today myopia affects a growing number of people worldwide among younger people. Why it happens?

Lack of outdoor activities and intensive screen use may accentuate it.

This eyesight problem is most often caused by an eye that’s too long,
where the distance between the cornea and the retina is too great. It
also can be caused by the cornea and/or lens being too curved for the
length of the eyeball. In some cases, myopia is due to a combination
of these factors.
Someone who’s myopic has difficulty seeing things far away because
the image is formed in front of the retina. However, s/he sees well
close-up. The more a person is myopic, the closer they need to get to
an object to see it clearly.

It is a common vision condition in which you can see distant objects clearly, but objects nearby may be blurry or requires a constant effort to see them, so, this can provoke .

In the case of hyperopia, the eye ball is too short meaning the distance between the cornea and the retina is insufficient. Consequently, the image of an object forms behind the retina.

It may also be caused by an abnormal shape of the cornea or lens.

A person with low hyperopia therefore can only see by constantly adjusting and accommodating their view.

Someone who is astigmatic has imprecise near and far vision. In
particular, peripheral vision images can sometimes appear deformed.
Astigmatism may be combined with other eyesight problems such as
hyperopia, myopia.

  • Headaches
  • Eyestrain
  • Distortion and blurred vision at all distances
  • Difficulty in driving at night
  • Squinting

Astigmatism is mainly caused by an irregular curvature of the cornea.
As a result, the image is not formed properly on the retina, but
distorted according to the curvature of the cornea.

Presbyopia is not a visual defect but a natural evolution of our vision.
No one is born with presbyopia but, we all develop it. It affects both
women and men from the early 40’s onwards.
It occurs when the eye is not able to focus clearly on close objects.

From 40 onwards, the lens loses some of its elasticity and its ability to
accommodate. It is no longer able to ensure adjusting focus to see
things close-up.
Symptoms include difficulty small print, having to hold
material farther away, headaches, and eyestrain.

If you are experiencing blurry vision when looking at far away
objects such as sign boards or advertising displays or struggling
to read things that are up close so it’s better to get your eyes
checked out by an eye specialist.


Most common causes:

Refractive errors – myopia, hyperopia and presbyopia.

But it may also indicate many other impairments

Working on digital displays for long hours without eyes
protection or struggling in driving at heavy lights for long
distances are main (but not only) causes for eye strain.
Symptoms of eye strain for people with pre-existing vision
conditions such as astigmatism (blurred vision), myopia
(nearsightedness) or hyperopia (farsightedness) can be worse.

Do you have trouble seeing well at night?
Most people noticing this problem when driving at low light
condition. They face more-than-normal difficulty seeing in
twilight or at night. If you also encounter the same then, you may
need to request your ophthalmologist to test it.
Although Poor night vision usually affect people as they age
(after 40s), but also can affect anyone at any age. The elder we
get the more light required; we may need twice as much light in
to see like an average 30 years old. But it’s also possible
that it can happen to anyone, at any age, even children as it can
be a symptom of another medical problem.

Vision problem can also cause , neck and shoulders
pain. Prolonged tension on the muscles of your eyes to
accommodate to different vision needs, may cause eye strain and
Try to adjust the distance to your PC not to be closer than 50 cm
from our eyes or depending on the size of the screen. Monitor
should be on the same level of your eyes or just below.
you should get your eyes examined as soon as possible in case
you have an undiagnosed vision problem that requires

UV light (Ultraviolet)

Studies show that excessive doses of UV light can cause irreversible eyesight problems.

UVA rays can penetrate your eyes and cause damage to your retina, leading to blurred or distorted central vision. EYE Doctors explains that absorption of UV rays can impair your cornea and lens, which can result in eye sunburn, dry eye syndrome, or cataract development.

Facts :
  • Even with our backs to the sun or in the shade, UV rays can reach our eyes.
  • Children, as they have larger pupils and more transparent ocular media than adults, they are more sensitive to bright light and UV.
  • UV radiation is harmful for the anterior part of the eye: cornea and crystalline lens.

Cumulative exposure to UV from the sun accelerates the aging of cornea and the crystalline lens and is a risk factor in cataracts.



Blue – Violet Rays

Harmful Blue Light emitted from digital devices causing eye
strain and more vision trouble to the retina.

Risks of overexposure

• Prolonged exposure to blue light may cause tired eyes, poor
visual contrast, eye strain, dry eyes, and headaches. macular
degeneration and retinal diseases risk increases.
• The risk is even higher with children as the lens of their eyes are
more transparent, allowing in more blue light from tablets and
TV screens.
• Blue-light also Decreases melatonin causes a disruption of the
sleep cycle
