As you grow older you will begin to notice changes in your body. You will also begin to notice that your vision is starting to change, particularly when you reach age 60 and older. Some of these age-related changes to your eyes are perfectly normal and do not indicate that you are suffering from an eye disease or abnormality. Some people, however, do experience more serious age-related eye disorders. There are a number of ways in which aging affects the general structure and function of everyone’s eyes. Such as:
- Reduced pupil size
- Dry eyes
- Loss of peripheral vision
- Weakening colour vision
- Vitreous detachment
There are also somewhat more debilitating conditions or diseases such as;
Once you reach 40 and above you will start to notice that it is becoming more difficult to focus on objects that are close up. This is known as presbyopia. It is a perfectly normal change in vision and occurs due to a hardening of the lens in your eyes. Initially, you may be able to compensate for this change by holding your newspaper or book further away. Gradually it will worsen and you will need to wear corrective glasses. Presbyopia advances more quickly beyond 50 and you will notice that you will need your prescription lenses change more frequently.
Around half of all Americans aged 65 and above have some stage of cataract formation in their eyes. Once you reach 70, the percentage increases dramatically. These days surgery for the removal of cataracts is safe and so effective that it can restore 100 percent of vision. See here for information on the best laser surgery in the U.K.
Glaucoma is a degenerative disease of the eye which causes progressive damage to the optic nerve and eventually leads to irreversible loss of vision. It is the second most common cause of blindness throughout the world. Glaucoma affects between one and 200 people age fifty and younger and one in 10 eight and older. It is treatable with laser surgery.
Macular degeneration is a disease of the eye that causes deterioration of the pigment in the centre of the retina. It is the number one cause of irreversible blindness in men and women above 65 years old. Macular degeneration is not reversible though it can be treated with medication and vision therapy.
Protecting Your Eyes With Lutein
Lutein has been found to play an important role in protecting our eyes and vision. It appears to work in two ways; acting as a natural sun block and neutralizing free radicals that can damage the eye. Lutein is an antioxidant that protects cells against damage from naturally occurring chemicals known as free radicals. Free radicals are singular or groups of atoms, which can cause damage to cells, impairing the immune system and leading to infections or sometimes degenerative disease, including damage to the eyes and vision. Because one of the main causes of macular degeneration appears to be sun damage to the sensitive tissue, lutein, acting as a natural eyeshade, may protect the retina against too much light.
