Vision Care For Old Age People
Physical changes are associated with old age people, including vision. It is inevitable to consult a doctor and check for conditions such as glaucoma, cataract and macular degeneration on a regular basis. If there are no eye disease symptoms, one should visit a doctor every two to four years after forty years of age. After 60, the visiting frequency must be increased, that is, once in a year. People suffering from diabetes should check regularly once in every year. Some conditions show no symptoms at first and affect our eye slowly. That is why it is recommended to visit a doctor once in a year.
The eye is like a camera. The front part of the eye focuses the image and sends it to the back part, which contains special nerve cells. They carry the picture to brain and some react to light. When excess pressure builds up on eye, it damages the picture carrying cells and it is called Glaucoma. The vision loss caused due to glaucoma is permanent. It can be cured by lowering the pressure in eyes and by early detection. It doesn’t show any symptom and is usually painless as the cells are not completely damaged at a time. It takes years for the damage to develop.
The image is focused on the retina which is at the back of the eye. It is called macula and it tends to change by ageing and causes loss of sharp vision. Sometimes macula breaks down and new blood vessels grow where they should not. Some of the symptoms associated with macular degeneration are: dark spots or shadows appearing in field of vision, broken vision and loss of sharp vision. There is no cure for this but early detection can solve this problem to an extent.
Cataract is a common phenomena associated with ageing. The lens turn cloudy and the only treatment are by removing the lens. The cloudy lens is removed and replaced with an IOL lens and just needs local anaesthesia.
Low vision is also associated with ageing and people suffering from it find it difficult to recognize faces, reading, driving etc. Aids such as contacts and prescription glasses can help during this stage and usually people lit their home bright when they suffer from low vision. Regular blood and oxygen supply to eyes is very important and try to keep the weight as per normal BMI. Exercises such as yoga and meditation are necessary and will keep your eyes and overall body condition healthy. Insomnia is also associated with this age and one should always wear protective eyeglasses when going out to protect eyes from UV rays. Adequate sleeping is also important for our eyes. Risk of fall is likely to happen at this age and so make sure bath tub and mats are slippery proof. Make sure there are no loose railings and sharp corners and edges of furniture are cushioned.
If one experiences any problems related with eyes, consult a doctor as soon as possible.
