The opposite of nearsightedness is far-sightedness, or hyperopia. With this disorder, the lens of the eye focuses images behind the retina, making nearby objects appear blurry. Astigmatism, happens when the eye lacks a single point of focus. This can be the result of an abnormality within the lens. Some objects may appear blurry while others clear. Retinal detachment is not always painful but you definitely must seek medical attention as soon as possible because eventually it can cause blindness. Colour blindness is when people see colours normally in bright light but cannot tell the difference between reds and greens in dim light. If you experience difficulties seeing properly at night, you may have a deficiency in vitamin A, or a disease of the liver or retina. Traditional Treatment If you are having difficulties with your vision, it is wise to seek the advice of an optometrist who will perform eye test.
