Why eyes need protection?

Vision occurs when the light captured by our eye get interpreted by our brain. Light enters through the transparent surface of eye called cornea. It continues through the pupil- that can dilate and expand to control the amount of light. The colored portion of eye called iris which is a muscle controls the retina size. Light then reaches the lens. Lens focuses light on retina. The retina converts light energy into a nerve signal which is carried to the brain where it is interpreted.

Ageing and power of vision:

Power of eyes gets reduced as the age increases, because the structure of eyes changes as we become older. The cornea becomes less sensitive, so that the injuries remain unnoticed. The pupil may lose its elasticity and response to dark and bright light. The most common problem that occurs at old age is the difficulty to focus eyes on something close. This condition is called presbyopia.

Another problem during old age is the gel–like substance inside your eye starts to shrink. These results small particles called floaters in your field of vision. Aging of eyes results the retarded production of tears. This leads to the condition called dry eyes. This condition can be relieved by using eye drops.

Some common eye conditions during old age are:

Presbyopia:

It is the loss of ability to see small print or close objects. It is a normal process that happens slowly over a lifetime. People who have presbyopia often have headaches or tired eyes.

Floaters:

Floaters are tiny spots that float across the field of vision. Floaters are normal, but can sometimes be indication of any eye problems such as retinal detachment. If you notice a sudden change in the number of spots, see your eye specialist immediately.

Dry eyes:

This condition happens when tear glands cannot make enough tears. This results in itching, burning or even loss of vision. Dry eye is common in older people, especially in women.

Cataracts:

Cataracts are the condition at which a cloudy area formed over the lens. This cloud hinders the vision. Cataract surgery can restore vision.

Glaucoma:

This condition occurs due to the high fluid pressure inside the eye. During the early stage of glaucoma, the affected person does not suffer from any pain or irritation. Glaucoma can be treated with eye drops, lasers or surgery.

Prescription glasses:

Most of the common eye diseases can be cured or prevented by prescription glasses. Eye care should be started at the early stage itself. Frequent eye check-up will also help to cure most of the eye conditions at the beginning stage. Use of Branded Sunglasses while going out will prevent ultra violet rays from reaching eyes. Sunglasses with colored lenses are much effective in providing a cool vision.

While you are going out, it is important to wear at least a fashionable eye wear that covers your eye completely, so that external particles such as dust or germs do not enter into eyes. Also it will help to avoid early wrinkling of eyes due to the over exposure to sunlight.  For more information, visit  http://www.forbeseyecare.co.uk
