What is Presbyopia?
Have you noticed yourself holding menus and books at arm’s length as you tryto read the tiny print? You most likely have presbyopia, the gradual loss of the ability to focus on small objects. Don’t panic, it’s not a medical emergency. However it is an irreversible, common part of aging.
It typically begins to advance around the age of 40 and may continue to worsen until about age 65. At first, you may notice that you are holding objects a bit farther away from so you can focus on them. You may also find that when you read the newspaper, for example, the words are beginning to blur. Visit your optometrist for a basic exam and to discuss these changes in your vision. It differs from farsightedness, which is the result of the shape of the eyeball. Your doctor can easily tell you which one you have.
Presbyopia is the result of the lens slowly hardening, which naturally occurs as it ages, as well as the weakening of muscles surrounding the lens. In a youthful eye the lens is flexible, allowing it to quickly adjust from close up to far away. However, as you age it becomes more difficult to make that change. As a result, near images are no longer in focus.
Even if you haven’t needed vision correction in the past, you aren’t immune to it. If you already wear glasses, a doctor may suggest bifocals or progressive lenses so that you can continue to see normally. If you wear contact lenses, he or she may recommend using a pair of reading glasses. Another option is wearing one lens for distance and the other for near vision. The brain then learns to rely on one eye for differing tasks. Depending on the person’s age, LASIK surgery can sometimes be performed to create this same monovision effect.
While growing older is a key factor, other medical conditions can increase your risk of developing it. Diseases such as diabetes, cardiovascular issues and multiple sclerosis can all increase your likelihood. Frequent use of antidepressants, antihistamines and diuretics can speed up the possibility as well.
There’s little chance of escaping it, no matter how many pennies you drop into the Fountain of Youth. While developing presbyopia may bea hit to your ego, realize that it is a natural part of aging. Visit with your eye doctor to determine that there is no other issue, and then go shopping for a smart pair of reading specs. To learn more about Lasik Surgery in La Mesa please visit this website.
