The eye sight chart is a device that helps measure subjective visual acuity.



People with myopia, also known as nearsightedness, can’t see objects that are far away. Because their eyes are longer than normal, the light that enters them becomes focused in front of the retina instead of on it. This results in blurred images. This vision problem affects about 15% of the population and usually develops during the teenage years. The condition usually gets worse over time, but it may slow down by the time a person reaches their twenties. A person with myopia will have trouble reading small print, and will need glasses or contact lenses.


Another common cause of eye sight problems is strabismus, or “lazy eye”. This condition affects one or both eyes and makes it difficult to focus. It is often caused by poor coordination between the two eyes, and can lead to headaches, difficulty in reading, and fatigue.

double vision

Another common problem is double vision. If you experience double vision, you should visit an optometrist immediately. This problem causes an irritated eye and can be a problem with reading or balancing. It can even affect your night vision. If you are experiencing eye sight problems, you may want to consider treatments. These can range from eye exercises to eye drops. The first step is to determine what your problems are. 

refractive errors

The most common sight problems are refractive errors, which cause blurred or distorted images. These are thought to be caused by environmental and hereditary influences. Depending on the severity of the problem, you may require a combination of treatment methods. If your condition is mild, you may not need a prescription or any treatment at all.
However, if your eyes are moderate to severely hyperopic, you may consider corrective surgery. If you suffer from nearsightedness, you may also require contact lenses or eyeglasses. Eye problems caused by uncorrected refractive errors may also be the cause of a headache. Refractive errors are the most common vision problems
In some cases, surgery is the only way to correct eye sight problems. In the US, over 150 million people wear prescription eyeglasses. But advanced surgical and medical techniques may be necessary to correct more severe problems. If you are experiencing eye sight problems, it is vital to schedule an appointment with an eye doctor.

affect over

They affect over 150 million people in the United States and can result in blurred vision and other vision problems. Other vision problems include astigmatism, a condition caused by the cornea becoming abnormally curved. Astigmatism, or “age-related” vision loss, is a condition that usually causes a gradual loss of ability to focus on nearby objects. Another condition that affects vision is amblyopia, also known as “lazy eye,” which causes poor vision in one eye. Amblyopia can be caused by refractive error, cataract, or strabismus. Thankfully, early treatment can help prevent amblyopia. A doctor may prescribe glasses or contact lenses or a medication to correct the problem.


A doctor can prescribe anti-inflammatory medications or a prescription eye drop if the problem persists. In cases where a refractive error is causing the eye to misalign, a doctor can perform a laser surgery.
