Vision is a vital factor that plays a significant role in good readability, scanning, focusing and visual coordination skills that are required daily. Therefore, it is important to keep a tab on the identifiers of vision problems
It is a bit complicated to give a single definition of a healthy eye. However, an eye can be claimed to be healthy based on three factors – visual acuity, eyesight and vision – that measure the quality of our vision. Let us understand what these terms mean how do they help in judging the health of an eye.
- Visual acuity: This is the sharpness of our vision and is commonly measured by identifying letters or numbers from a specified distance on a standardized eye chart.
- Eyesight: Eyesight doesn’t have one definition, however, mainly defined as the ability and sense to see.
- Vision: Vision is a broader term that includes contrast sensitivity, ability to track moving objects accurately, colour and depth perception and a good focusing speed and accuracy.
All the above-mentioned factors together help in deciding the healthiness of an eye. Therefore, it is important for one to preserve its vision and understand signs and symptoms that indicate the presence of vision problems. The most common and easily identifiable are:
- Eye strain
- Double vision
- Glare or halos around bright lights
Therefore, it is suggestible to always consult a healthcare specialist (optometrist or ophthalmologist) on a regular basis or when any of the signs and symptoms are observed and get a comprehensive eye examination and vision evaluation to protect our eyes and vision
