Getting a proper eye exam is a must if you want to avoid developing refractive errors. An eye exam starts with a visual acuity test that measures how well you can see things. This test involves looking at a chart that contains letters in different sizes. Your vision will be measured in relation to normal vision, and the doctor will determine if you have a refractive error. If you do, you will need a prescription for glasses or contact lenses.
Refractive errors affect the way light enters the eyes, which makes objects appear blurry. They can be congenital or developed later in life. A thorough eye examination will diagnose refractive errors and recommend the appropriate eye care treatment. Luckily, many of these errors can be corrected. But there are still about 670 million people worldwide who do not have access to corrective treatments.
While refractive errors cannot be prevented, they can be diagnosed and treated, either with corrective lenses or surgically. If caught early enough, refractive errors can be corrected and do not prevent the full development of good visual function. The corrective measures vary widely based on the defect. The World Health Organization estimates that more than 150 million people in the world suffer from some form of refractive error, which excludes presbyopia.

Treatments for refractive errors can include eyeglasses or contact lenses, and even laser surgery. The most popular and safest method for resolving refractive error problems is using eyeglasses. Eye doctors can customize the lenses in eyeglasses to correct the refractive error and place the refractive focal point on the retina for optimal clarity.

A recent survey found that only about half of optometrists are making recommendations regarding omega-3 fatty acids. Most optometrists believe they don’t know enough about the benefits of omega-3 fatty acids for eye health, and another thirteen percent feel that there isn’t enough published evidence to make a recommendation.
Recent research suggests that omega-3 fatty acids are useful for people with glaucoma. They can decrease intraocular pressure and increase ocular blood flow.
Glaucoma is the second leading cause of blindness in the world, with an estimated 80 million people affected by the condition by 2020. For more info click here solbriller kristiansand .
Another seven optometrists said it was beyond the scope of their practice to give nutritional advice to their patients. They also improve optic neuroprotective function.
At present, approximately three million individuals are blind because of the disease. Omega-3 fatty acids may also be helpful in treating dry eyes. In one study, mice that were fed a diet rich in omega-3 fatty acids showed fewer signs of dry eye and less inflammation.
They also showed reduced risk of developing glaucoma, a condition that occurs when the pressure inside the eye becomes too high. Moreover, rats fed an omega-3-rich diet showed regulated inner fluid flow.
Another study from the National Eye Institute has found that eating oily fish twice a week reduced the risk of developing wet macular degeneration, a disease characterized by gradual vision loss in the center of the field of vision.
