Eye diseases common in children

There are many eye conditions and diseases that can affect a child’s vision and influence every aspect of his or her life. Two of the most common eye problems in children are amblyopia and strabismus. Amblyopia is a vision development disorder caused by one eye not being able to see as well as the other. The brain sees two different pictures that it can't combine in a meaningful way, so it ignores the image from the weaker eye and chooses to interpret only the image sent by the stronger eye. The result is that the eye that isn't seeing well will not develop properly. More common in preschoolers is a problem with eye muscles called strabismus. In this condition eyes are unable to focus both eyes in the same direction accurately, which makes the eye appear lazy. If it is not treated, strabismus can also cause amblyopia.

Eye diseases common in seniors

Vision loss among the elderly is a major health care problem especially by the age of 65. The most common causes of vision loss among the elderly are age-related macular degeneration, glaucoma, cataract and diabetic retinopathy. Age-related macular degeneration is characterized by the loss of central vision. Glaucoma results in optic nerve damage and visual field loss. Because this condition may not have any symptoms initially, regular screening examinations are recommended for elderly patients. Cataract is a common cause of vision impairment among the elderly, but surgery is often effective in restoring vision. Diabetic retinopathy may be observed in the elderly at the time of diagnosis or during the first few years of diabetes. Patients should undergo eye examinations with dilation when diabetes is diagnosed and annually thereafter

Why are eye vitamins necessary?

Eye vitamins are designed to focus directly on eye health and therefore can help prevent many diseases. Although we can obtain all the vitamins and minerals we need by eating certain foods, it is nearly impossible in these fast food-oriented times to get a healthy meal with all the vitamins and minerals we need. That is where eye vitamins come in. Even if you exercise regularly and eat a healthy diet with plenty of fruits and vegetables (and substituting fish for red meat a few times each week), you may be able to do even more to protect your vision by taking a daily nutritional supplement.

Eye structure

Lens: The lens, by changing shape, helps the eye focus on objects at various distances.
Retina: The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.
Macula: the macula is a part of the retina responsible for detailed central vision.
Vitreous: The vitreous humour is the clear gel that fills the space between the lens and the retina of the eyeball.
Optic nerve: The job of the optic nerve is to transfer visual information from the retina to the vision centres of the brain.
Iris: The colored part of the eye is called the iris and It controls light levels inside the eye.
Cornea: The cornea functions like a window that controls and focuses the entry of light into the eye.
Pupil: The pupil is the opening in the center of the iris. The size of the pupil determines the amount of light that enters the eye.
Aqueous humour: the aqueous humour is a colorless fluid similar to plasma that supports the lens.
Sclera: The sclera is commonly known as "the white of the eye." It is the tough tissue that serves as the eye's protective outer coat.

What is eye health and why is it important?

Eye health is the term used to describe the taking care of your eyes to prevent any diseases or treat any unpreventable diseases to make your life more enjoyable. Healthy vision can help keep people safe and also help ensure a healthy and active lifestyle well into a person’s later years. The eyes are an important, but often overlooked, part of overall health. Eyes should be constantly checked for a comprehensive dilated eye exam, which can help detect common vision problems, and eye diseases that can easily be treated. Vision loss and low vision can affect many aspects of a person’s life forever. However, paying extra attention to your eyes can guarantee a healthy and happy life
