Disorders of Refraction and Accommodation: A Brief Overview

Disorders of refraction and accommodation are common eye conditions that affect people of all ages. Refraction is the ability of the eye to bend light and focus it on the retina, while accommodation is the ability of the eye to change its focus from distant to near objects. When these abilities are compromised, it can lead to vision problems.

1. Myopia: Myopia, also known as nearsightedness, is a common disorder of refraction that affects people who have difficulty seeing distant objects clearly. This occurs when the eyeball is too long or the cornea is too curved, which causes light to focus in front of the retina instead of on it.
2. Hyperopia: Hyperopia, also known as farsightedness, is the opposite of myopia. People with hyperopia have difficulty seeing near objects clearly, and this occurs when the eyeball is too short or the cornea is too flat, causing light to focus behind the retina instead of on it.
3. Astigmatism: Astigmatism is a condition in which the cornea is irregularly shaped, causing blurred or distorted vision. People with astigmatism may experience difficulty seeing both near and distant objects clearly.
4. Presbyopia: Presbyopia is a condition that affects people over the age of 40. It occurs when the lens of the eye becomes less flexible, making it difficult to focus on near objects. People with presbyopia may need reading glasses or bifocals to see up close.

These disorders can be diagnosed through a comprehensive eye exam that includes a visual acuity test, a refraction test, and a dilated eye exam. Treatment options depend on the specific disorder and may include corrective lenses, such as glasses or contact lenses, or refractive surgery, such as LASIK.

It is important to have regular eye exams to detect and treat disorders of refraction and accommodation early to prevent vision loss or other complications. If you are experiencing vision problems, schedule an appointment with your eye doctor to discuss your treatment options.
