Peek Acuity is a smartphone-based vision check app developed by eye experts to allow anyone to check visual acuity using only an Android smartphone. Peek Acuity helps screen and identify people who need further examination.
Simply start the test and stand 1.6 meters or 5 feet away from the monitor. When you see a character on the screen, only decide the direction and wait for the answer to appear at the bottom of the screen. The answer is in green color and also a big font, so you can see it without any problems from distance.
Visual acuity is usually measured using a Snellen eye chart. Eye charts can measure how well you can see at a distance, and this is where the term “20/20 vision” originated from. During an eye exam, your ophthalmologist will ask you to read a set of letters set in multiple lines, from biggest to smallest.
Use the online ZEISS Online Vision Screening Check[1], which was developed by ZEISS experts to allow you to test your eyes in an easy and fast way – for free. At the end of the test you will then receive a recommendation indicating whether you should consult a ZEISS optician for professional advice.

Blurry Vision
Difficulty focusing on blurred objects—far away or up close—may mean you need glasses. If you find it difficult to read street signs while driving or read text in books, you may benefit from eyeglasses or contacts.
Having 20/20 vision means you have normal or average, vision. Some people have vision that's better than 20/20, like 20/15 vision or 20/10 vision.
-3.00 diopters or less is mild. -3.00 to -6.00 diopters is moderate. -6.00 to -9.00 diopters is severe. -9.00 diopters or more is extreme.
Australia used to follow the imperial system but switched to the metric system last century like many other countries. Some countries like America continue to use the imperial system. This means that an Australian optometrist or ophthalmologist will record your distance vision in metres, rather than feet.
If your number is between +0.25 and +2.00, you have mild farsightedness. If your number is between +2.25 and +5.00, you have moderate farsightedness. If your number is greater than +5.00, you have high farsightedness.
If you have blurred vision, the things you see will not look sharp and clear. You may experience blurred vision in both eyes or just in one eye, depending on what is causing it. Sometimes everything you look at will be blurry, while sometimes just part of your field of vision will be blurred.
A refractive error is a disorder that happens when the eyes can't focus images correctly. The term includes these conditions: astigmatism, farsightedness and nearsightedness. You can often correct these conditions with eyeglasses, contact lenses or surgery. Refractive errors are the most common cause of blurred vision.
How does the Google Cloud Vision API work? The Google Cloud Vision API uses machine learning to identify images from pre-trained models on huge datasets of images. It then classifies the images into thousands of categories to pick up on objects, places and faces and produces the results with a confidence value.
Cloud Vision allows developers to easily integrate vision detection features within applications, including image labeling, face and landmark detection, optical character recognition (OCR), and tagging of explicit content.
Visual acuity less than 20/200 is considered legally blind, but to actually fit the definition, the person must not be able to attain 20/200 vision even with prescription eyewear. Many people who would be legally blind without eyewear can function well in everyday life with appropriate glasses or contact lenses.
If your prescription is -2.5 or lower, this means that you are legally blind. Visual acuity of -2.5 is equivalent to 20/200 vision. Visual acuity of -3.0, for instance, means that you have 20/250 or 20/300 vision. From there, visual acuity of -4.0 means that you have 20/400 vision.
Is There A Cure For Myopia? There is no definitive way to permanently end shortsightedness just yet. However, prescription glasses, contact lenses and eye surgery are effective measures for improving eyesight. Regular eye check-ups with an optometrist will help monitor myopic cases and ensure optimal eye health.
If you're legally blind, your vision is 20/200 or less in your better eye or your field of vision is less than 20 degrees.
