Eyesight Changes that Come with Aging

Certain eye diseases associated with aging can appear suddenly. They may be a previous untreated problem or simply genetic origins (several family members have or have had eye problems at some point in their life). Whatever triggering or predisposing factors, you should go to your ophthalmologist regularly, regardless of age.


Evolution of vision throughout a person’s life

– Childhood – At birth, children are very sensitive to light and they cannot focus the objects and distinguish colors well. Their eyesight, however, continues to develop in the first months of life. Up to one month, babies can focus on objects within a view distance of up to 3 meters. After four months, they can see things from a room quite clearly distinguished and a full range of colors and shades. Vision problems such myopia and amblyopia or lazy eye can be detected at these ages. Approximately 1 in 4 school-aged children have vision problems, most often suffering from myopia. Experts recommend eye examination before starting school and then every two years. As they eyes develop as the child grows, myopia gets worse until the age of about 20 years.

It was also found that 3 percent of all children are affected by amblyopia. This disease occurs when nerve signals between the brain and eyes not working properly. Most of the children can be successfully treated by applying a patch over the healthy eyes or other methods.

– Maturity – healthy adults, younger than 40 years, have a pretty good view. To maintain healthy eyes is necessary to wear sunglasses, protective equipment at work and at home. Also, avoid dryness, fatigue and eye strain by limiting time spent in front of the monitor or TV. The need of wearing bifocals when reading is a classic sign for middle aged people. The condition is called presbyopia , is normal and a result of reduced flexibility of the eye lens.

– Old age – Among the diseases that can have negative effects on vision include diabetes and hypertension. Diabetes is a leading cause of blindness incidents in adults, as it can trigger retinopathy. High blood pressure can cause permanent vision loss due to damage to the blood vessels and nerves. Cataracts and glaucoma are eye diseases more common in people over the age of 60. Cataract is the clouding of the eye lens. However, it can be removed and replaced with a special lens during surgery. Glaucoma is eye nerve damage as a result of aging. Glaucoma is accompanied by increased ocular tension. Treatment can be both medicinal and surgical and aims at lowering eye pressure. Macular degeneration can be treated or not, depending on its type. In some cases it can cause partial loss of vision.

To maintain eye health eat foods rich in omega 3 fatty acids, vitamins C, E and A.
