Vision is among the primary senses of human beings. Poor vision hinders your ability to perform basic tasks such as reading, walking and typing. Certainly, the eyes are delicate and require lots of care. You can have perfect eyesight during early childhood but ruin it as you grow up. Prolonged exposure to lots of light, electronic screens and dirt. In such cases, you need to undergo a comprehensive eye examination by an optometrist. He or she will determine the condition affecting your eyes and carry out the necessary procedures needed to restore normalcy. If you are taking an eye test for the first, here is what you should expect.
Colour blindness does not qualify as a type of blindness in which you cannot see at all. It's just a deficiency in the way you identify and see colours. In most cases, colour blindness is a hereditary condition passed down through genetic composition. The optometrist performs various tests when examining patients for colour blindness. The most popular one is a screening test using a special booklet containing circular patterns made up of small dots with different colours. The dots vary in brightness and size. The arrangement of the dots enables a person with normal vision to see a digit within the circle. The optometrist can tell that you are colour blind if you cannot see the digit within the circular pattern. You could also be colour blind if you see a different digit from the one expected by the optometrist.
Proper vision requires excellent teamwork and coordination between your eyes. The cover test is the most common way of examining how your eyes work together. During the test, the practitioner will ask you to focus on an object placed across the room. He or she then covers your eyes alternatively as you look at the target object. In the process, the doctor monitors the movement of the uncovered eye to see if it has to move in order to pick up the target object. This could show mild binocular vision problems and symptoms of eyestrain.
Depth perception also goes by the name stereopsis. It helps you perceive and appreciate the three-dimensional vision of objects. During a test of depth perception, you look at a sheet with test patterns. The test patterns comprise four circles. The objective of the test is to have you identify the circle that looks closer to you when compared to the others. If you identify the right circles, then your eye-teaming abilities and depth perception are normal.Share

When I first started noticing veins protruding from my lower legs, I did my best to ignore them. However, I knew they were likely varicose veins, as both my parents have had varicose veins for several years. Eventually, I went to see my doctor due to experiencing leg swelling and red patches of skin, which turned out to be varicose eczema. I was prescribed the usual treatment, and my doctor discussed surgery to strip out the damaged veins, but I decided to postpone surgery and look at managing the swelling and protrusion of veins naturally. I started this blog to share my own experiences of trying complementary therapies, such as homeopathy, herbal medicine and massage, to manage my symptoms. I hope you find my posts useful and interesting.
