Patients with presbyopia can benefit from bifocals to improve both near and distance vision. In most cases, prescription eyewear such as glasses or contact lenses can effectively restore vision. To accurately detect and diagnose nearsightedness, farsightedness, presbyopia, or astigmatism, children, teens, and adults should have routine eye exams scheduled once a year. In addition, patients with astigmatism may have difficulty easily shifting the focus of the eyes from near to far and vice versa. As a consequence of the imbalanced curve, light focuses on multiple points of the retina rather than a single point, causing overall vision to distort, blur, or double. Symptoms of presbyopia can also include frequent headaches when trying to focus for long periods of time at books or computer screens as well as eyes that become easily fatigued.Īstigmatism is characterized by a cornea with an imbalanced curve, and is often diagnosed along with nearsightedness or farsightedness. This common condition – which results from a stiffening of the eyes’ lenses – often develops gradually with age, and men and women in their 40s and beyond are at a greater risk for developing presbyopia. In addition, presbyopia can prevent the eye from easily shifting focus from near to far and vice versa. Presbyopia is characterized by an inability of the eye to focus on objects very near or very far. This common refractive error is not typically diagnosed during vision tests at schools since a full eye exam is required to detect the condition. In some cases, blurry distance vision may also result. Consequently, light focuses beyond the retina rather than onto the retina directly, ultimately causing near vision to blur. Symptoms of myopia often include difficulty seeing movie screens, televisions, projection screens, or school boards.įarsightedness – otherwise known as hyperopia– is characterized by a cornea that is too flat or a shortened eye. This common refractive error typically begins to develop during the teenaged years, and while the condition is normally progressive, the vision can stabilize during adulthood. Consequently, light focuses in front of the retina rather than onto the retina directly, ultimately causing distance vision to blur. Nearsightedness – otherwise known as myopia – is characterized by a severe curvature in the cornea or an elongated eye.
