Eye examination is ideal every two years if you are generally healthy, below 60 years old, without eye health issues (family history of blindness, glaucoma, lazy eyes), without systemic medical conditions (diabetes, hypertension, hypercholesterolemia, HIV), and you’re not a contact lens wearer. It is highly advised to have a yearly eye examination for those who wear contact lenses because these are prosthetic devices by the FDA and monitoring is required on its impact to eye health at least once a year. What is 20/20 eyesight? The 20/20 vision is the normal human vision, wherein 20/20 letter is the size an average person can read without wearing eyeglasses from a distance of 20 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 are considered fashion accessories because they come in stylish purses and belts. Are you aware that eyeglasses may come in different types of lenses? In the past, eyeglasses are generally made of glass that can break easily, but now, eyeglasses are generally made of high-tech plastics, are lighter, filter-treated, and don’t easily break. The following high-tech plastic lenses are thinner, lighter, and more scratch-resistant than older plastic lenses: polycarbonate, aspheric, photochromic, trivex, high-index plastic, 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 changes from clear to tinted under the sun that don’t require the wearer to replace eyeglasses with sunglasses. 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.
