Common Vision Problems Requiring Vision Correction
Most people that have vision correction needs suffer from common vision problems related to refraction, which is the bending of light as it passes through the eye. A refraction error occurs when the shape of the eye prevents light from passing through the cornea to focus correctly on the retina, causing the image to appear distorted by the brain.
Common refraction errors include:
- Nearsightedness (Myopia): a refractive eye condition where objects near by appear clearly while, objects further away appear blurry.
- Farsightedness (Hyperopia): a refractive eye condition where objects in the distance appear more clearly while objects nearby are blurry.
- Astigmatism: a refractive condition in which the eyeball is not perfectly round, but rather is shaped more like a football. This causes the light passing through the cornea to be bent in manner that stretches or distorts the image on the retina.
- Presbyopia: more common in adults age 35 and older, this refractive condition affects ones ability to focus on objects up close. As the eyes age the lens has more difficulty changing shape to focus on close objects.
Most of all refractive errors can be corrected with prescription lenses. The best way to assess the amount of refraction and correction needed is with a comprehensive eye exam.
Other signs or symptoms of vision problems or eye conditions that may be more severe include:
- Itchy, watery, burning or gritty eyes – These are common signs of evaporative dry eye, a condition that is cause by dysfunctional meibomain glands in the eyelids. Treatment options include warm compresses, drops, or in more advanced cases, LipiFlow treatment.
- Conjunctivitis – An eye infection more commonly referred to as “pink eye”. This type of eye condition is characterized by red, itchy, painful eyes and is often accompanied by some form of discharge (can be white, yellow or green). Bacteria, viruses or irritants entering the eye cause this kind of infection. Treatments vary from prescription eye drops to oral antibiotics.
- Sub-Conjunctival Hemorrage (Blood-filled eye) – This is a condition in which small blood vessels in the conjunctiva rupture, causing a very red-looking eye. Often times there is no pain or discomfort. The cause can be random or an indicator of underlying issues. We recommend scheduling an appointment for immediate evaluation to ensure it is not the result of a more severe issue.
- Moderate to severe light sensitivity – Signs of light sensitivity indicate the presence of inflammation inside the eye. This can be from a corneal infection or from an internal eye problem. In either case, it is important to have your eyes evaluated by an eye doctor.
- Blurred vision – Any sudden blurring of vision, whether in one eye or both eyes, warrants an immediate visit with one of our expert eye doctors.
- Floaters – Sometimes described as “gnats” floating around in ones vision is an eye condition that many people have. While common, floaters can be a sign of a more serious eye problem, especially if there is a sudden onset of new floaters. You should let your doctor know if you see floaters in your vision.
- Flashes of light – Flashes of light in your vision are more serious and usually indicate some sort of retinal issue such as a tear, hole or detachment. If you experience these signs, you should see an eye doctor immediately for an eye examination.
- Headaches – Persistent headaches in the front of your forehead could be a sign that you are experiencing eyestrain and having difficulty focusing. This may indicate that your prescription is not accurate.
