Most of us will experience temporary eye problems from time to time, including itching, blurriness or fatigue. Most of these eye problems are short-lived and will probably go away on their own with no complications. However, sudden eye problems and those that last for more than a couple of days should be checked by an eye doctor. The following is a list of common eye problems and their possible causes.

Causes

Common eye problems can be caused or exacerbated by certain conditions – such as Glaucoma in the case of diabetes. Other times, common eye problems  are caused due to eye infections such as Conjunctivitis and Episcleritis. Certain ocular diseases can even come from sexually transmitted diseases such as herpes and genital warts. If contact between the eye and area of infection occurs, the STD can be transmitted to the eye.
Eye problems can also be age-related in cases involving Bitot's Spots, Cataracts, Floaters and in more severe cases, Macular Degeneration.

Puffy eyes

Puffy eyes refer to the swelling of tissues around your eyes. It is usually onlya temporary cosmetic concern and may simply disappear without any treatment.

Puffy eyes can result from various reasons including heredity, fluid retention dueto weather or Hormone levels, allergies, certain medications, staying up at night,etc. If puffiness does not go away or you notice swelling in other parts of thebody, see your doctor to rule out other possible causes of swelling such as kidneyor Thyroid problems.

Refractive errors

Refractive errors occur when the image of the object you are looking at is not focusedproperly onto the Retina (the light sensitive tissue in the back of the eye) causingblurred vision. In normal vision, the image of a viewed object needs to be focusedon the Retina.

The exact cause of refractive errors is not understood yet, but it is known thatboth heredity and environmental factors can affect their development.

Refractive errors can be classified as:

Myopia (Nearsightedness) is a refractive error where distant object comes into focus in front of the retina of the eye as a result of longer than normal eye-ball, so the distant object appears blur to the myopic eye.

A bent concave lens is used to bring the focus on the retina to restore clear distance vision.

However, the myopic eye can still see near objects clearly without any correction depending on the distance of the near objects in relation to the degree of myopia.

It's important to detect and correct young children (under 6 years old) with moderate to high monocular myopia to prevent Amblyopia (lazy eye).

Hypermetropia (Longsightedness) is a refractive error where distant object comes into focus behind the retina when the eyes is relaxed.

In adults, this condition will cause deterioration of distance vision and near visual problem due to the gradual loss of focusing ability of the eye. A bent convex lens is used to bring the focus back onto the retina.

In children, distance vision is often not affected because of the active and strong focusing mechanism, the eyes have ability to bring the focus back onto the retina. However, for higher degrees of hypermetropia, it may cause blurred vision, headache, and even converging squints. These problems will be aggravated when doing near works which required greater focusing power.

It's important to detect and correct the medium to high degrees of hypermetropia for children under 6 years old. If uncorrected, it can lead to Amblyopia.  

Natural Treatment for Eye Care

Take some petals of rose and mix them with raspberry leaves. Put the both in a glass of water. Leave it for few hours and wash your eyes with that water. This natural treatment provides fast relief to day long tiring eyes.

Carrot is beneficial in naturally treating eyes. Carrots contain beta-carotene, which is the precursor of vitamin A in the body. Vitamin A is essential element of body. Vitamin A is responsible for strengthening the eyes and protecting them from night blindness

Eye Care Diet

The intake of vitamin A is of the utmost importance for improving vision. The good sources of vitamin A are spinach, cheese, turnip, milk cream, butter, tomatoes, lettuce, carrots, cabbage, soy beans, green peas, fresh milk, oranges, and dates. So, all these should be added to diet chart.
