Prescription of corrective lenses:3Over the counter correction
July 27, 2008 – 11:40 pmFrom Wikipedia.com
In some cases, mild farsightedness (hyperopia) can be treated with simple magnifying lenses or commodity reading glasses that can be purchased without a prescription. The magnifiers make the image of the object being viewed bigger so that it can be seen better.Over the counter readers are spherical corrective lenses of varying strengths (commonly +1.00D to +4.00D).These treatments are not as tailored to the specific needs of the patient. A difference in refractive error or presence of astigmatism will not be accounted for. The use of improper corrective lenses may not help or could even exacerbate binocular vision disorders. Over the counter readers may not work for patients with significant refractive errors requiring distance correction (unless they are used in combination with contact lenses that correct distance vision). Eyecare professionals (optometrists and ophthalmologists) are trained to determine the specific corrective lenses that will provide the clearest, most comfortable and most efficient vision, avoiding double vision and maximizing binocularity. They can tell patients if over the counter corrective lenses are appropriate.
