Eyesight is one of the greatest gifts we are blessed with by nature. Ask a blind person the value of this blessing. Those who can see the beauty of colors and calm their inner selves with the serenity of mesmerizing sceneries are among the most fortunate souls. Unfortunately, sometimes we have to suffer from medical conditions that affect our eyesight. If these problems are not treated on time, some of them can lead to permanent vision loss.
Thanks to the progress in medical science, glasses can correct most vision problems. Moreover, eyeglasses can also serve as a shield against harmful environmental effects on our eyes. For example, blue light blocking glasses save us from the detrimental ultraviolet rays as well as the blue light rays being emitted by the screens. Famous brands like GlassesUSA, RayBan, LensDirect, and Overnight Glasses offer blue light prescription glasses to protect your eyes from both blurry vision as well as detrimental environmental factors.
Glasses or contact lenses correct vision by allowing the eye to concentrate light on the retina’s correct spot, the spot where the picture is most precise. Since everyone’s eyes are different, a pair of glasses that lets one person see clearly can make another person’s vision unclear.
Purpose of eyeglasses:
Eyeglasses are used to fix vision issues. Eyeglasses will help if you have difficulty seeing up close or at a distance. They allow you to see objects more clearly and sharply at any distance. The way light falls on the eye causes the majority of vision issues. The retina is situated near the optic nerve in the back of the eye. The eye’s lens transmits light to the retina, transforming it into signals and transferring them to the brain. The photos we see are the product of this process.
If due to some eye structure changes, light fails to fall at the correct point, the images we see are not clear. Eyeglasses aid in the proper concentration of light on the eye. Different eye vision problems can be corrected with the help of eyeglasses.
Below we have discussed the most commonly found eye conditions that can be treated with the help of eyeglasses.
Hyperopia:
This eye problem is also known as farsightedness. It refers to a medical condition where vision is blurry for close objects but clear for distant objects. When the eyeball is short than average or when the cornea isn’t evenly curved, farsightedness occurs. Light rays fall behind the retina, causing blurry vision.
Symptoms:
- Feeling difficulty in focusing on near
- Headaches are
- Vision is hazy.
- The strain on the eyes.
Causes:
The leading cause of this problem is a shorter eyeball.
Treatment:
You can have some treatment choices if you are hyperopic. They include contact lenses, photorefractive keratectomy, eyeglasses, and LASIK. Your optometrist will help you decide the best treatment plan for you and suggest your eyeglasses accordingly.
Myopia:
This eye condition is also known as nearsightedness. It refers to vision that is sharp and clear for near objects but blurry for distant objects. When the eyeball is longer than its average size, then it usually happens. Nearsightedness can be observed during regular eye examinations.
Symptoms:
- Vision becomes hazy.
- To see clearly, you must squint or partially close your eyes.
- Driving a vehicle can be difficult, particularly at night.
Causes:
The light can not reach your eye retina appropriately if your eyeball is too long or your cornea is too curved. Instead of focusing directly on the retina, the light-sensitive portion of your eye, the image is made in front of it.
Treatment:
This eye problem is usually treated with photorefractive keratotomy, eyeglasses, acrylic corneal implants, contacts, LASIK, and radial keratotomy.
Presbyopia:
It is also known as aging eyes. It refers to a state in which the lens loses its flexibility, making it challenging to focus on near objects. Presbyopia is an unavoidable aspect of aging.
Signs and Symptoms:
- Keeping reading materials away from one’s face to make the letters easily readable.
- At a standard reading distance, vision is blurred.
- After reading, you can experience eye pressure or headaches.
Causes:
Aging causes the thickness of natural eye lens as well as reduced flexibility to focus.
Treatment:
Corrective lenses such as bifocals, trifocals, multifocal contact lenses, and single-vision reading glasses can help. Your eye doctor will check to identify your vision condition severity and prescribe the best treatment plan for your eyes.
Astigmatism
Astigmatism is a disorder in which the pupil of your eye isn’t perfectly round. It is a refractive defect in which light is not concentrated uniformly on the retina by the eye. At any distance, this causes blurry or blurred vision.
Symptoms :
Astigmatism has the following symptoms:
- Eye pressure and headaches
- Difficulty in driving at night
- Blurry vision
- Strained or fatigued eyes
- Having difficulty in seeing at night
Causes:
The majority of people are born with it, but scientists are puzzled as to why. It may also occur as a result of an eye injury, illness, or surgery.
Treatment :
Almost all cases of astigmatism can be corrected with glasses or contacts. However, if you only have mild astigmatism and no other vision issues, you may not need to wear eyeglasses.
