Eyeglasses Essentials – Things You Need to Know


Eyeglasses these days have become more than corrective or therapeutic in nature – they have become part of the fashion world as belts and bags are. It is not unusual to see famous fashion brands like Guchi, Calvin Klein and Nike on frames these days.

Common Lens Types

A few decades back, lenses were only made of glass. But they have evolved with the advancement of technology. Modern lenses are now far better because unlike glass they are lighter and harder to break. Moreover, they can be treated with filter to protect your eyes from harmful ultraviolet rays of the sun.

Modern lenses are lighter and thinner than glass or older plastic lenses. They are also resistant to scratch so you don’t really have to worry about them too much. These lens types include:

Polycarbonate

Lenses made of polycarbonate materials are ideal for athletes or sports enthusiasts. They are also useful for men and women whose work exposes their glasses to vibration and possible damage. If you have kids who tend to get tough with your specs, these lenses are for you.

Trivex

Like polycarbonate, trivex lenses are thin, lightweight and impact-resistant. You may use these corrective lenses if you are exposed to an environment that can put your glasses in peril.

High-index Plastic

If your eyes need super thick, old school prescription lenses, you can now settle for thinner, lighter high-index plastic lens.

Aspheric

Various degrees of curvature allow aspheric lenses to become thinner or flatter to provide users a bigger portion of its surface.

Photochromic

This type of lens can change from clear to dark depending on the amount of sunlight in the area. They can eliminate your need for sunglasses. Photochromic lenses may remain clear in your car especially it its windshields have UV protection. They are available in glass or plastic.

Polarized Sunglasses

Polarized sunglasses have lenses that reduce glare from surfaces. They’re really great for sports and outdoor activities like driving. Polarized sunglasses have one common weakness though – they often make it hard for you to see the LCD on the dashboard of your car.

Multifocal Lenses

Multifocal lenses are prescription lenses intended to correct visual impairment. They are commonly prescribed to people 40 years old and above. You will recognize this type of lens by lines that divide the lens into sections. But that was in the past. Today’s multifocal lenses are harder to distinguish.

Bifocals

Bifocals are split into two sections. The upper part is intended to allow a user to see with distance while the lower part is intended for near vision. These are designed for people who lose ability to focus due to age.

Trifocals

Trifocals are actually bifocals having a third section that sits above the bifocal part of the lens. You look through this third section to see objects like images from a computer screen.

The world has about 253 million people with impaired vision. Many of these people don’t have the chance to recover their sight. You should be thankful for your access to therapeutic and protective eyeglasses

Whatever type of lens is prescribed for you, it is really intended to protect your eyes, correct a vision problem or both. You should take good care of your eyeglasses particularly the lenses because they’re the ones that make life a bit easier for you. Remember, having impaired vision is not just the inability to see things clearly; it is also associated with other discomforts like headache, dizziness and double vision. When buying eyewear, make sure that they provide the correction or protection you want, just like the eyeglasses Edmond Oklahoma residents prefer.
