Buying your first pair of glasses can seem like an overwhelming task facing so many pictures on the walls and hearing about all those lens options. There is a lot to consider when buying glasses, whether they are for you or for a child. Read on for tips to help make the process a little easier.
Prescription
What do all those prescription numbers mean, anyway? It is a good idea to ask your optometrist or eye care professional to explain the prescription to you before you leave the office. If you’ve forgotten, your optician can explain this to you when you get your glasses checked, but here are a few tips:
-Glass powers are measured in diopters. A -1.00 means you are slightly short-sighted, or myopic, while -7.00 means you are very myopic.
-If your prescription has three numbers in a row, like this: -1.00 -.75 X 90, it means you are near or myopic and have astigmatism.
-If yours has only one number per line, you don’t have astigmatism. Your prescription, whether prudent or prudent, is considered spherical.
-OD stands for Oculus Dexter, Latin for “Oculus dexter”. OS Left Eye, or left eye. The right eye is always written first.
-If you need bifocals, the prescription will have a section called “add power”. This way you need glasses for distance and to get closer to things. This condition is called presbyopia, and it is part of the aging process.
Why are there so many different lenses?
Lenses come in many types for a variety of needs. If you need glasses to see at a distance or just to read, you only need vision lenses. If you need glasses near and far, you will need bifocals, trifocals or multi-focals.
Bifocals are lined lenses having one segment for distance and one for near. Trifocals have a third part of the middle line, such as the computers use. Many focal points are sometimes called “non-linear” or “progressive”. These lenses have no lines and allow excellent visual acuity in all focal areas. Multifocals are sometimes mistakenly called trifocals.
What are light lenses?
The lenses are light plastic lenses, sometimes called hi-index. The material they are made from has a higher refractive index, meaning they can bend more easily than regular plastic, therefore thinner. There are several types of light lenses. One of the most common is polycarbonate.
Polycarbonate is a great lightweight lens because it is even thinner and more resistant than regular plastic. Polycarbonate is recommended for kids, athletes or those who want safety protection from their glasses.
Light lenses are recommended for everyone, especially those with large or large prescriptions.
Which Framework Should I Choose?
Whatever style you prefer, the frames should be comfortable, for your lenses, and stylish.
Plastic tables are available in bold styles and colors that make a strong statement. Styles range from pale pink to rhinestone-black cat eyes, and everything in between. Classic, literate faces and figures are wild and unique constitutions of the plastic body.
Plastic plates are useful for thick lenses, which some mask the thickness of the rim. It is not a great idea to use sunglasses as they may warp if left in the heat or stored in a hot box.
Plastic boards tend to slip more often than metal boards because they usually don’t have adjustable nose pads.
Metal panels offer a lower profile look with subtle grooves and subtle colors. Colors range from basic gold and silver to rose, peach, pale blue, gray and black. If you don’t want to tell the world that you wear glasses, the choice is made.
Metal plates are also available in strong alloys, titanium alloys and even flexible styles that bounce back from the twist that a regular metal machine would break. Metal frames are for you if you want style and durability in your glasses.
Spring hinges are available in both plastic and metal panels. This hinge style does more to extend the life of your glasses than any other line. They are a real staple in children’s glasses and safety eyewear.
No matter what style you prefer, it should fit your body properly. The frame should be comfortable, resting gently behind the ears and adjusted to the plane of the nose. Temple ends that press and glasses that slide are common problems that can be adjusted by an optician.
<1> Which Lens Options Should I Choose?
The basic lens options that should be included in every pair of glasses are a scratch-resistant coating and ultra-violet protection. All lenses can be scratched, but a coating can be applied to make the surface of the lens harder. Ultra-violet coatings are known to filter out harmful UV rays to protect your eyes from sun damage.
Other popular options are anti-reflective coatings, tints and films that darken the lenses while remaining clear inside.
Anti-reflective coatings reduce glare caused by lens reflections. They also allow more light to reach the eye, so that they can see more clearly. This film is essential for computer use, long reading or driving at night.
Colors are generally paler for comfort, or much darker for sunglasses. Don’t protect your eyes from the sun ; you must have a UV coat to avoid sun damage.
Most optical shops will have the ideal lens and coating available. Be sure to ask about special treatments like polarized lenses and mirrors.
Finally, if a warranty is offered on the first pair of glasses, buy it. If you’ve never worn glasses before, you’re more likely to accidentally damage the frame or scratch the lenses. In most cases, the cost of the warranty is a fraction of the cost of replacing the broken lenses or scratched panels; You’ll thank yourself later for going ahead and providing protection.
Care for your glasses
Always keep your cups in the case lined with them. This is the best way to prevent accidents, like sitting on your windshield, which is the most common reason to replace it.
Wet the lenses carefully before wiping them; This will help prevent scratching. Always use approved detergent and 100% cotton cleaning. Don’t wipe them off with paper towels, kitchen towels, or your shirt, as all of these materials can scratch.
Bring your glasses to an optical shop every few months for an adjustment or minor repair. A nose pad that turns yellow or green should be replaced. It is a good idea to wash the entire pair in warm, soapy water once a week, especially during the summer months.
Finally, if your glasses are bent or crooked, bring them to an optical shop for adjustment. Reductive reflection is an exercise in opposites, and thin parts break easily. Repair kits can be purchased, but often the screws will not be the right size for certain frames. The optical shop will have all the varieties to suit your roof.
