For perfect vision, the image you see must be focused on your retina at the right point for the brain to translate the actual object. Sometimes due to multiple reasons that include aging and medical conditions, this does not happen perfectly.
The failure to focus leads to blurred vision, nearsightedness, or farsighted conditions that affect a patient’s quality of life. In extreme cases, you may need surgery to correct the condition, or the doctor can prescribe eyeglasses to improve your eyesight. Here’s how prescription glasses can help to maintain your eyesight.
What causes eyesight conditions?
Refractive errors are a common eye problem afflicting many patients and a cause of poor eyesight. This condition includes astigmatism or distorted vision at all distances, farsightedness, nearsightedness, and presbyopia or diminished focus up close.
Prescription eyeglasses can help correct these refractive conditions and generally sustain a patient’s eyesight. Ordering online is the quickest way to get prescription glasses once an optometrist has given the correct diagnosis.
Lifestyle habits and underlying medical conditions can lead to refractive errors and cause sight problems. Congenital predisposition is another consideration when diagnosing eyesight complications or taking preemptive measures to maintain eyesight.
Excessive screen time is also a leading cause of eyesight problems today. Blue light glasses are a great way to protect your eyes during screen time. If you spend a lot of time on the computer or watching TV without blue light glasses you’re straining your eyes. These lifestyle habits exert too much strain on the eyes and affect proper functioning and internal damage.
Low water intake and a poor diet are also contributory to dry, puffy, red eyes and diminished eyesight. Exposure to sunlight is as bad for your eyes as straining to work for long periods in dim light. Protect your eyes from extreme exposure to bright lights as well as dim lights to reduce the strain on focus.
How prescription glasses can correct nearsightedness
Nearsightedness, also known as myopia, is a common eye condition among many patients. Patients with this condition can see objects near to them more clearly than those that are at a distance. Myopia occurs when the natural shape of the eye changes and refracts light rays from distant objects incorrectly in front of the retina, giving a blurry vision.
In most cases, myopia runs in families and may start gradually or, in severe cases, rapidly hitting peak levels in adolescence. Symptoms present with blurry vision when looking at distant things, squinting to focus, poor sight at driving speeds, and eye strain-related headaches. Any or all of these symptoms are an indication you suffer from myopia and need to see a doctor.
The problem with myopia is the increased curvature of the cornea or extended length of your eye. Prescription glasses help correct these changes and maintain your eyesight for a better living experience. Your doctor will diagnose and prescribe the right lenses for you, and you can choose to have them in regular glasses or wear them as contacts for clear vision.
Prescription glasses for farsightedness
Some patients have a problem seeing objects up close but see things at a distance. Farsightedness or hyperopia occurs when light from near images falls behind the retina and out of focus. This condition creates problems for patients and especially students who find it hard to read at normal distances.
Hyperopia also runs in families and may be present at birth. Symptoms of farsightedness include eye strain, burning and aching eyes with a general discomfort or headache after prolonged reading or working at a computer. You have difficulty focusing on close objects which appear blurry and have to squint to see clearly.
When you experience these symptoms, it’s time to go for a refraction assessment to correct the anomaly. The refraction incompetence is caused by a decreased cornea curvature or a reduced length of your eye. The doctor can prescribe a variety of lenses to suit your needs, including monovision, bifocals, trifocals, multifocal, spherical, or toric contacts, and eyeglasses.
Manage presbyopia with prescription glasses
As we age, certain body functions start declining, and sometimes we lose them altogether. Presbyopia is one such sight function that deteriorates with age and can affect the quality of life in seniors. Presbyopia is gradual and starts in the mid-40s affecting the eye’s ability to focus on close objects.
When you notice that you are progressively holding books at arm’s length to see clearly, it is a sign you have presbyopia. The onset is age-related and mostly affects people between the ages of 40-65 who experience problems reading handheld material at a normal distance. They experience further difficulty reading in low light and suffer headaches or eye strain after such attempts.
An eye exam and refraction assessment will help the doctor prescribe the right lenses to maintain your eyesight. In most cases of presbyopia where patients have had perfect eyesight previously, you may simply need reading glasses only. The doctor will decide on the best lenses to use and advice on when to wear them for personal safety as they may not be suitable for driving.
