Achieving Clear Vision Through Prescription Eyeglasses Getting an eye exam every two years is sufficient if you are a healthy person, under 60 years old, with no eye health problems (glaucoma, family history of blindness, lazy eye), without systematic health conditions (high blood pressure, diabetes, high cholesterol), and you are not wearing a contact lens. Annual check-ups are recommended for those who are contact lens wearer. What does it mean by 20/20 vision? The normal human eyesight results in an eye examination is 20/20, wherein the 20/20 letter is the size a person with normal vision can see at a distance of twenty feet. A person with nearsightedness needs a round and smaller frame, and that is what an optician do, to fabricate lenses and adjust frames, eliminating visual disturbances such as the “fishbowl effect”. Eyeglasses do not only improve vision but are now also make fashion statement to the wearer. What are the different types of lenses? Unlike in the past that eyeglasses are generally made of glass, eyeglasses today are made of high-tech plastics and newer ones are lighter, can be treated with a filter to protect your eyes, and do not break easily. High-tech plastic materials may include polycarbonate, trivex, high-index plastic, aspheric, photochromic, and polarized sunglasses. Polycarbonate lenses are ideal for those who play sports, work with their eyeglasses, or have children tough on their specs. As compared to thick old-school eyeglasses, high-index plastic lenses are good for people who need strong prescription because these are generally lighter and thinner. Photochromic eyeglasses are like automatic sunglasses because exposure to direct sun changes the clear lens to tinted lens. Polarized sunglasses reduce glare from surfaces such as water, making it great for driving and sports. There are also different types of lens’ shape including concave lens for those with nearsightedness, convex lens for people with farsightedness, and cylinder shape for those with astigmatism. If a person have more than one vision problems, they need multifocal lenses such as bifocals or trifocals to correct their vision.
