As we age, our eyesight deteriorates steadily and almost everyone over the age of 60 years may need spectacles. There are also certain diseases which affect the vision in old age. With regular sight tests, suitable spectacles, surgery,
drugs and special visual aids, most people can maintain a good sight and lead a full and independent life.
Here are some tips to maintain a better eyesight:
It is recommended that one should have a sight test done at least once every two years and more frequently if one notices any change in one's vision. A sight test is not just a 'spectacles' test but a check-up of the health of one's eyes. If one has developed a new eye disease, it can be detected early. It is therefore very important to get the sight tested regularly.
- Spectacles and other low-vision aids
It is always advisable to use made-to-order spectacles which suit one's needs best. Now-a-days ready-made reading spectacles are also available. Though they may not harm one's eyes, ready-made spectacles can cause eye strain and headaches. If you find it difficult to perform your tasks, you can use magnifier. It makes things look bigger so that you can perform tasks easily.
The amount of light the eyes need at 60 years of age is about three times more than that requires at 20 years. You should ensure that there is adequate electric lighting in all parts of your home including stair case and toilets.
- Common age-related eye diseases
Eye problems and diseases are common in old age. Some of them cause progressive loss of vision. Among them cataract, diabetic retinopathy, glaucoma and age related macular degeneration are very common. Many eye diseases have no early signs or symptoms, but regular eye check up can detect eye diseases in early stages before vision loss occurs. Early detection and treatment can help you save your sight.
