The retina can be found at the back of the eye and it is very sensitive to light. The retina transmits the images to the brain. Disorders of the retina (which can be treated with eye care) include:

1. Macular pucker.
2. floaters.
3. Retinal detachment.
4. Macular hole.

Cloudy Cataracts

It has been estimated that over 50% of US citizens (by the time they reach the age of eighty) have some form of cataract problem, often needing to resort to surgery. Again, a variety of symptoms are evident:

1. Double vision.
2. Unclear vision.
3. Glare.
4. Difficulty seeing during the evening.
5. Frequent prescription changes for glasses and contact lenses.
6. Colors appearing paler than normal.

It usually takes quite a while for cataracts to develop and eventually it may be necessary to have a man-made lens fitted. However, some good advice for preventing cataracts developing include wearing sunglasses and wide-brimmed hats.

Optic Nerve

The optic nerve can be damaged by glaucoma which occurs when the fluid pressure in the eye rises to such an extent that it puts pressure on the nerve itself. You might find that there is a history of glaucoma in your family. The over 60s are also prone to this condition. It can be treated using eyedrops and/or surgery, but it is good advice to get an eye exam at least every two years to check that all is okay with your vision.

The upshot to all of this is to take your eye care seriously and have frequent checks on the condition of your vision. Early detection of any problems could be vital in finding a suitable and effective treatment.
