If you have difficulty seeing things further away, you may have myopia, also known as nearsightedness. Nearsightedness is caused by a cornea that is curved or an eyeball that is too long. The light rays focus in front of the retina (the surface at the back of the eye), instead of on it. A person with myopia may have difficulty seeing road signs, movies at the theater, or reading from the board in a classroom. Additional symptoms of myopia include squinting, eye strain, and headaches. A person who is experiencing any of these symptoms needs to be evaluated for corrective eyeglasses in Wichita, KS.
An eyeglass exam is conducted by an optometrist. The exam will test the clarity of vision. This is done through reading a chart of letters. Peripheral vision, eye muscle control, and pupil reaction are also evaluated. After getting a general idea of a patient’s corrective needs, the optometrist will conduct a refraction test to fine tune the prescription. In a refraction test, the optometrist flips through different levels of corrective lenses and the patient indicates which options appear clearer.
An accurate prescription will include the specific corrective needs of each eye. A papillary distance measurement (the number of millimeters between the two pupils) is also necessary for ordering eyeglasses. Once a prescription is complete, the patient is ready to get eyeglasses in Wichita KS.
Frames come in a variety of materials, styles, and colors. Metal and plastic are two of the top choices. Some frames are flexible, which make them resistant to becoming distorted after falls or being sat on. Lens options include plastic or glass material. Coatings are also available for improved performance. An anti-reflective coating will improve night vision and diminish the affect of glares in sunlight. A UV-coating can be clear and will help protect the eyes from ultra-violet sun light, which can cause cataracts or other eye problems.
Difficulty seeing things at a distance is symptomatic of myopia and may require corrective lenses. Corrective lenses will reduce eye strain and allow clearer vision. Corrective lenses may also reduce headaches due to eye strain. An optometrist can evaluate the eyes and prescribe corrective lenses to lessen the effects of myopia.
