To be short-sighted, or myopic, means that a person has difficulty seeing objects clearly at a distance while having relatively clear vision for nearby objects. It occurs when the eyeball is slightly longer than normal or when the cornea (the clear front surface of the eye) is too curved. As a result, light entering the eye focuses in front of the retina instead of directly on it, causing distant objects to appear blurry.
To remedy short-sightedness, an optician may suggest the following options:
1. Prescription glasses: Wearing glasses with concave lenses helps to redirect the light entering the eye, allowing it to focus correctly on the retina. These glasses will have a negative power, indicated by a minus (-) sign on the prescription.
2. Contact lenses: Similarly, contact lenses with a negative power can be used to correct short-sightedness. They sit directly on the eye and provide a wider field of vision compared to glasses. However, contact lenses require proper hygiene and regular maintenance.
3. Refractive surgery: For individuals seeking a more permanent solution, refractive surgeries like LASIK or PRK can be considered. These procedures reshape the cornea to correct the refractive error, allowing light to focus properly on the retina. However, it is important to note that refractive surgery carries potential risks and complications. These can include dry eyes, glare, halos, double vision, and even a loss of vision in rare cases. It is crucial to consult with an eye specialist to thoroughly understand the risks, benefits, and suitability of surgery based on individual circumstances.
The specific recommendation will depend on factors such as the severity of the short-sightedness, personal preferences, lifestyle, and overall eye health. It is advisable to consult an optician or ophthalmologist for a comprehensive eye examination and personalised advice.
