Undergoing Color Blindness Test

The genetic state and deficiency in viewing definite and certain colors, which takes place in 8 percent of men and 0.5 percent of women is called color blindness or also known as Daltonism. It is passed through a defective faulty chromosome, which can be detected through an uncomplicated eye examination. Most patients who suffer from this kind of deficiency can actually see several kinds of colors, but they find it hard to recognize one color from the other, especially the colors green and red.

The retina is composed of cones and rods that work as light and color receptors. When these receptors fail to function correctly, you will not be able to recognize all types of colors. This defect takes place when one of the receptor cones lacks color. The cones situated in your eyes have blue, green and red pigmentation. Normally, the cones in your eyes will react when exposed to lights of those colors. Color blindness takes place through the person’s gene. The case is always inherited and males are more likely to obtain it rather than females. Most cases show that green and red are more difficult to identify for a patient with this deficiency. Being unable to identify the color blue is also common.

Unluckily, there is still no treatment to alleviate color blindness, but it should not get into your day-to-day activities too harshly. This deficiency is normally present at the time of birth through inheritance. On the other hand, conditions such as cataracts and diabetes can also result to alteration in vision. As a result, you will have to book an appointment with your eye doctor as soon as possible.

If you want to know if you are color blind or if you already know but want to make sure of your eyes’ capacity, you have to check yourself through the color blindness test. This is a free and fun way to undergo an eye examination. It caters to anyone of all ages and it offers various choices for you to try your vision. The examination is supported by plates that are pseudo-isochromatic. You will be shown figures and numeric characters to check if you can precisely tell what the image is. It will only take a few steps for you to finish the test and the results will come out as soon as possible with accurate outcome. This eye examination will check which color you do not recognize. The green and red is the most popular case of color blindness. You will be asked to take a look at the images with colored dots and spots. On each plate that is shown, there will be a number with a background composed of different colors that can only be identified by those people with normal visions, but not by those who have color blindness. Each plate projects variation of color combinations that aids the specialist in defining which cell is primarily affected.

The test is a very simple one. It is effectively fun, child-friendly and fast so you never have to worry to undergo it.

CR-39 began the change of optical lenses from glass to plastic materials. It is lighter weight, more impact resistant than glass lenses; thus, becoming a popular type of material used in single vision, bifocal, and multifocal or progressive lenses.

Material is low price and easy to manufacture. It is often preferred by individuals on a tight budget. However, because of its 1.50 index, customers with high prescription powers are recommended to use higher index lenses such as 1.56, PC, 1.67, or 1.74 lenses.

CR39 Lenses Features are:

Fragmentation: When plastic lens breaks, it breaks into larger fragments than their glass counterparts. Furthermore, the fragmented pieces are not as sharp as glass.
Fogging: CR39 lenses are less likely to fog-up than glass lenses because it responds more favorably to temperature changes.
Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: CR39 lenses have much lower internal reflection and surface glare than glass materials.
Tinting: CR39 lenses are great for tinting. Lenses can be tinted to virtually any color. Even lenses with variable thickness are able to be tinted evenly.

If you want thinner, lighter lenses, and have an milder prescription, then mid index lenses are the way to go. As prescription increases, the lenses become thicker. Thicker lenses increase internal reflections that reduce vision quality. Furthermore, thicker lenses add to the weight of each pair of glasses reducing comfort. Mid-Index lenses refract the light at a greater angle allowing the wearer to have a beautifully thin and light pair of glasses.

Mid Index Lenses Features are:

Fragmentation: When plastic lens breaks, it breaks into larger fragments than their glass counterparts. Furthermore, the fragmented pieces are not as sharp as glass.
Fogging: Mid Index lenses are less likely to fog-up than glass lenses because it responds more favorably to temperature changes.
Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: Mid Index lenses have much lower internal reflection and surface glare than glass materials.
Tinting: Mid index lenses are also tintable, so you can get that pair of sunglasses you’ve been eyeing for so long.

Polycarbonate lenses has a high index of refraction 1.59 and low density making PC lenses 20% thinner and 25% lighter than regular plastic lenses. Polycarbonate lenses are the most impact resistant lenses on the market. Therefore, it is the industry standard for safety goggles, and highly recommended for kids' lenses.

Polycarbonate Lenses Features are:

Impact Resistant: Polycarbonate material was originally made for uses on canopies covering fighter planes and then made its way into space on astronaut visors and space shuttle windshields. Today it is readily available to the public. It impact resistance makes the material extremely suitable for sports, industrial safety goggles, and children's eyewear.
Scratching: The reason for polycarbonate lenses' impact resistance is because of its "softness". Softer materials will flex instead of fragment when met with great force. However, the property allows lenses to be scratched easily. Therefore, every single one of our polycarbonate lenses is multi-coated with hard coating that forms a protective layer around the lenses allowing the lenses to be free from scratches while retaining its impact resistant qualities.
UV Protection: Polycarbonate lenses inherently carries UV protection properties that blocks nearly 100% of the UV rays from entering the back of the retina.

If you want thinner, lighter lenses, then high index lenses are the way to go. As prescription increases, the lenses become thicker. Thicker lenses increase internal reflections that reduce vision quality. Furthermore, thicker lenses add to the weight of each pair of glasses reducing comfort. Hi-Index lenses refract the light at a greater angle allowing the wearer to have a beautifully thin and light pair of glasses.

High Index Lenses Features are:

Fragmentation: When plastic lens breaks, it breaks into larger fragments than their glass counterparts. Furthermore, the fragmented pieces are not as sharp as glass.
Fogging: High Index lenses are less likely to fog-up than glass lenses because it responds more favorably to temperature changes.
Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: High Index lenses have much lower internal reflection and surface glare than glass materials.
Tinting: High index lenses are also tintable, so you can get that pair of sunglasses you've been eyeing for so long.
