You see very clearly.
Lights, shadows and shades stand out especially clearly for you. There's no fogginess and you see and detect objects precisely even in poor weather and dimly lit conditions.
Contrast vision stands for the ability to distinguish colours, shadows, and shades.
Our ophthalmologist Markku explains this indicator:
Test results for contrast vision are in the form of percentages: the ratio of the dimmest figure that you can see to its background. The ratio between pitch black on a white background is 100 percent. 10 percent is already much dimmer, but most people see it easily. A ratio of one percent requires very good vision. Thus, the smaller the percentage, the better the result.
If your contrast vision has declined it may be difficult for you to distinguish the shapes of objects or to see them at all, if they are situated on a similarily colored background. Dark time of day or bad weather can diminish the differences, and contrast vision usually also declines with age.
Eye diseases such as cataracts, glaucoma, or diabetes can reduce one’s contrast vision even if one’s visual acuity remains good.
Lowered contrast vision can be improved for example by improving lighting or by using the right kinds of sunglasses or eyeglasses. Dry eyes may also affect contrast vision, in which case eye drops can help.
Signs of deteriorating contrast vision:
Ocusweep functional vision examination measures the functioning of the visual system with both eyes - just as we use both eyes simultaneously in everyday life. This measurement is not a replacement for an eye health examination, where each eye is tested on its own while the other eye is blindfolded.
