Ever wonder why older people prefer books with larger font sizes? Because as you age, the lens of your eye grows less flexible, decreasing your ability to focus on near objects. This is known as presbyopia.
Those with undiagnosed presbyopia may hold books, magazines, newspapers, and menus at arm's length to be able to focus properly. In addition to reading, performing other close-range activities, such as sewing or handwriting, may also result in headaches, eyestrain or fatigue. When it comes to dealing with presbyopia, there are a number of options available, which take your eyewear preferences into account.
Reading glasses are great but are only useful for those who wear contacts or for people who don't need to wear glasses for correcting distance vision. You can purchase these at lots of stores, but it's advised not to purchase a pair until you have spoken with an optometrist. This is because reading glasses may be handy for brief periods of time but they can lead to fatigue with extended use. Not surprisingly, custom-made readers are a far more effective solution. These can do a number of things, like rectify astigmatism, comfortably accommodate prescriptions that vary between the two eyes, and on top of that, the optic centers of the lenses can be specially made to suit whoever is wearing them. The reading distance can be adjusted to meet the individual's needs.
If you already have glasses, consider bifocal or multi-focal corrective lenses, or the popular progressive addition lenses (PALs). These are eyeglasses with multiple points of focus; the lower portion helps you see nearby objects. Contact lens wearers should speak to their eye care specialist to find out about multifocal contact lenses, or a treatment approach called monovision. Monovision is when one eye wears a lens for distance vision and one eye wears a lens for close vision.
You need to periodically adjust the strength of your lenses, because your eyes and vision change over time. However, it's also important to look into your various choices 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 unbiased perspective. Presbyopia is an inevitability of aging, but the decisions you make about it is always up to you.
