At Al Hajal Optometry Centers we use the latest and the finest types of frame lenses available in the market, in order to ensure the health of the eyes of our patients and to guarantee the quality of every prescription eyeglasses we offer to them.
The followings is information about every type of lenses available at our optometry center.
As technology advances, so do lenses. In the past, they were made exclusively of glass. Today, most are made of high-tech plastics. These new ones are lighter, don’t break as easily as glass, and can be treated with a filter to shield your eyes from damaging ultraviolet (UV) light. These lenses are lighter, thinner, and more scratch-resistant than glass or the older plastic types.
These impact-resistant lenses are a good choice if you play sports, work where your eyeglasses could easily get damaged, or have kids who are tough on their specs. They also have built-in UV protection.
They’re made from a newer plastic that’s similar to polycarbonate lenses. They’re lightweight, thin, and impact-resistant. They may also correct vision better for some people.
If you need a strong prescription, these lenses are lighter and thinner than the old-school super-thick ones you may have had in the past.
These have various degrees of curvature. That means they can be thinner and flatter so you can use a much larger portion of the surface.
Sunlight changes these from clear to tinted. You may no longer need sunglasses, although they may not darken in your car if the windshield blocks UV rays. They can be either glass or plastic.
These lenses reduce glare from a surface like water, so they’re great for sports and driving. But they can make it hard to see the liquid crystal display on your car’s dashboard.
Your unique vision problem will determine the shape of your lens. You’ll need a concave lens (curves inward) if you’re nearsighted. A convex lens (curves outward) will help if you’re farsighted. If you have astigmatism, your cornea is shaped wrong, so your lenses may be more like a cylinder. Simply put, the lens is a tool you use to focus light onto your retina in the correct way.
What Are Multifocal Eyeglass Lenses?
If you have more than one vision problem, you’ll probably get glasses with multifocal lenses, like bifocals or trifocals. These have two or more prescriptions to correct your vision. In the past, you could spot this type of lens by the line between the two sections. But today’s products often look seamless.
The most common type of multifocal. The lens is split into two sections. The upper part helps with distance vision. The lower half is for near vision. They’re usually prescribed for people over 40 who can’t focus well anymore. That’s due to presbyopia, an age-related change that affects your eye's lens.
These are bifocals with a third section. It sits above the bifocal portion of the lens. You look through it to see objects within arm's reach, like a computer screen.
Eyeglass Lens Coatings
There are almost as many coatings as there are lenses:
Anti-reflective. It can help with glare, reflections, halos around light, and make for a nicer look.
Scratch-resistant and ultraviolet coating. Most lenses today have these built in.
Sometimes, a light or dark hint of color on the lens can help you see better. A yellow tint may increase contrast. A gray tint to your sunglasses won’t change the colors of things. A light tint can hide signs of aging around your eyes.
This is purely for looks, but it does hide your eyes from view. You can find them in a range of colors like silver, gold, and blue.
How Should You Care for Your Eyeglasses?
- Always store them in a clean, dry place away from things that can hurt them.
- Clean them with water and a non-lint cloth. That’ll keep them spot-free and help you see clearly.
- See your doctor yearly to check your prescription.
Glasses can correct some common vision problems, but don’t forget to schedule your FREE routine "EVERY 6 MONTHS" eye exams at our AL HAJAL Optometry Centers to keep your eyes healthy.
