Are you realizing that the world around you is getting a little out of focus lately? You're not alone. In fact, in the US 75% of Americans need vision correction. While problems with vision can put a damper on your activities, in most cases, it can corrected with the help of prescriptive eyewear. Below are some of the most common problems that most people experience that can corrected with the use of contact lenses and eyeglasses. If any of the conditions below describes your vision, make sure to schedule an exam with your eye doctor.
People with farsightedness can see objects clearly at a distance, however, they find it hard or impossible to focus when up close. And in more severe cases, it takes a continual effort from them to focus on objects at all distances. Farsightedness can interfere with the person's writing reading, and other close-up fine-motor tasks. This can even lead to eye strain, fatigue, and headaches.
The majority of farsightedness can be corrected with contacts and eyeglasses that make use of convex lenses. These lenses are thicker at the center and thinner at the edges and they are designed to bend light toward the center and to move the focal point forward so that the light is being focused on the retina.
In contrast to farsightedness, people with nearsightedness have difficulty seeing objects at a distance. Their vision is clear when up close, like a few inches away. However, beyond this distance the object becomes fuzzy and out of focus. Myopia interferes with daily activities like driving, sports, classes, even recognizing people at a distance. It also causes headaches, fatigue and eye strain.
When it comes to correcting myopia, a contact lens or an eyeglass with concave lens is used. It is thinner at the center than the edges. This is used to direct light away from the center and move the focal point of the light back, for it to reach the retina.
Are you having difficulty reading the newspaper? Presbyopia is a kind of age-related condition and this happens to everyone. When a person reaches the age of 40 or 50, it becomes harder to focus on nearby objects, such as magazine or book print, especially when in low light. When presbyopia is left untreated, this can lead to eye fatigue and headache when performing close work. Presbyopia can be corrected with a bifocal or multifocal eyeglasses, or a reading eyeglasses. A bifocal or multifocal contact lenses can also be used.
If you are having difficult focusing at a distance, you may have astigmatism. This is a condition that affects many people. People who are suffering from astigmatism experience a blurry or distorted vision at all distances. This may vary depending on the strength of astigmatism. Astigmatism is usually treated with eyeglasses, or a specially designed contact lens. The lens is thicker in the middle and thinner toward the edge.
Vision is vital to the overall well-being of a person, both children and adults. A poor vision or when having eye and vision problems, performing daily activities will be harder or a lot different. Therefore, it pays to have a regular check-up with an eye doctor, regardless if you have or no vision problem. After all, prevention is always better than cure.
