With aging comes many challenges. Among them is the loss of good eyesight. Many things, as a result, become a challenge, such as doing daily chores, driving, walking, and reading, just to name a few. It is quite a bewildering experience, especially when you had good eyesight for much of your life. Some of the most common age-related eye conditions you have at that age include cataract, diabetic eye disease, glaucoma, dry eyes, and low vision.
Another eye-related problem common among older people is presbyopia, a condition that involves a steadily diminishing ability to focus on near objects as you age. It also needs corrections for other eye conditions like myopia, astigmatism, and hyperopia to name a few. Presbyopia usually sets in when you are aged somewhere between your mid-30s to 50s, though most get it around their mid-40s. Younger sufferers usually contract them earlier because of conditions such as diabetes, and the like.
Signs that you may have presbyopia include trouble reading fine prints in newspapers or the yellow pages, distance vision staying blurry even after a few moments of looking up to take a break from reading among others. You usually could deal with the problem in its early stages (the first 1-2 years) by adjusting your reading distance, increasing brightness, and taking breaks from close work. Afterward, correction becomes necessary.
Thankfully, there are many products in the market today that can help you correct it, They include bifocal contact lenses and bifocal glasses. Due to some issues regarding bifocal contact lenses such as irregular distance vision and terrible near vision, more people with presbyopia prefer the glasses. Among the more common types of bifocal glasses are bifocal reading glasses, and bifocal safety glasses.
If you need to have these glasses, it is important to take note of a few things when buying any type of bifocal reading glasses. They are:
1) The objective of bifocal glasses is to compensate for the eye lens reduced accommodative power. This is done by using plus lenses similar to a magnifying lens. These will require stronger glass prescriptions every couple of years until you hit your mid-50s or 60s as your eye lens changes. You normally do not have to continue upgrading them past that point unless you get other eye problems.
2) Most people usually experience side effects with glasses when they first use them, like headaches and dizziness. Thankfully, most do adjust eventually. How can you get there? First off, you have to know that bifocals are two lenses in one. The bottom and top segments have different scopes of focus. The bottom is used for focusing on closer objects, and the other for more distant objects. The trick to adjusting properly is to learn when and where to use each part of the lense. For example, the bottom half should be used when you are looking at something close at hand, like the book you’re reading. Conversely, the top half is for looking at something somewhat far, like the wall clock on the other side of the room.
There are more pointers on how to make using them easier. Remember to consult a professional first before buying any kind of eye care product to deal with whatever eye ailment you have, always consult a professional first.
