As the age-old expression goes, “seeing is believing,” so what happens when your eyesight is faulty? When you take eyesight into consideration, seeing things blurred or clear is vital when looking at how vision shapes our reality. Can you read that sign 20 feet from you? Is it slowing down your day and mentally taking a roll? When it takes longer for you to physically perceive the reality around you, it takes the edge away from your mental being. 8358691955_7fa6cd731b_b

With that said, it is important to identify what eyesight problems you may have, as well as what kind of corrective aids would best adhere to your current lifestyle. Below we discuss and give a brief overview of some of the most common vision problems.

Astigmatism can be attributed to the irregular shape of the cornea or the lens. The distortion of shape prevents light from focusing correctly on the retina, thus making vision blurred at any distance. Often times, astigmatism can be accompanied by other vision problems, like nearsightedness and farsightedness. Depending on your lifestyle, astigmatism can be treated in a multitude of ways that consist of eyeglasses, contact lenses and surgery. Replace My Contacts have plenty of products that address this specific condition, including Acuvue Oasys for Astigmatism and Air Optix Toric.

Nearsightedness, also known as myopia, is a condition where objects close appear to be in focus and clear and objects far away appear to be blurred and out of focus. This eyesight condition occurs when light comes into focus right before the retina instead of on the retina. The several ways to correct this condition is to opt for eyeglasses, contact lenses or even refractive surgery, which aims to permanently change the shape of the cornea to improve vision.

Farsightedness, also known as hyperopia, occurs when objects in the distance appear more in focus than objects that are near. People with farsightedness focus on images behind the retina rather than on the retina. Just like nearsightedness, this eyesight condition can be corrected with eyeglasses, contact lenses and refractive surgery. 

astigmatism-v6Presbyopia, an eyesight condition that develops with age, makes it difficult to see objects up close due to the lens not being able to change shape enough to focus. This type of eye condition mostly effects adults, ages 35 and up. For this type of circumstance, eye glasses are the best way to correct vision.

A Cataract is another eye sight problem that can be contributed to aging and is very common among older adults. When this occurs, there is a clouding of the lens that affects the vision, which can be in one or both eyes. Those who have prolonged exposure to sunlight, certain diseases like diabetes and habits like smoking and alcohol are more at risk for a cataract. Eye glasses and brighter lighting are a few things that can be used to help in mild cases.

It is important to have periodic eye exams to check on the health of your eyes and evaluate different aspects of your vision. If you believe there is an issue with your eyesight, do not hesitate to make an appointment with an ophthalmologist to figure out what could be triggering the problem.
