Did you ever wonder why older people prefer books with larger font sizes? With age, your eye's lens is likely to become more and more inflexible, decreasing your ability to focus on near objects. The clinical term for this is presbyopia. And, it's something that eventually happens to everyone.
Often, to avoid eyestrain, people with untreated presbyopia tend to hold printed text at arm's length to be able to focus properly. Additionally, engaging in other tasks at close range, like embroidery or writing, can also cause headaches, eyestrain or fatigue. In order to treat presbyopia, there are a few options, which take your eyewear preferences into account.
Reading glasses are an easy choice but are only useful for those who wear contacts or for people who don't already need glasses for issues with distance vision. You can get these almost anywhere, but it is not recommended to purchase a pair until you have had a comprehensive eye examination. Lots of people aren't aware that reading glasses may help for brief blocks of reading time but they can eventually cause fatigue with prolonged use.
And for those who already have glasses, but don't want to switch between pairs of glasses, consider bifocal or multi-focal corrective lenses, or PALs (progressive addition lenses), which are quite popular. Essentially, these are glasses that have more than one point of focus; the bottom portion helps you see things at close range. If you wear contacts, speak to us to discuss multifocal contact lenses. Additionally, you may be able to benefit from a treatment technique called monovision, where one eye wears a lens for distance vision and one eye wears a lens for close vision.
Since your vision continues to change with age, you should expect your prescription to increase periodically. But it's also important to examine your options before you decide the direction you want head in when it comes to your vision; presbyopia can affect you, even if you've had refractive surgery.
Ask your eye doctor for an informed view on the matter. Presbyopia is a reality of middle age, but the decisions you make regarding it is always up to you.
