EyeGlasses: Glasses are the most common form of eyeglasses used to correct or improve a variety of vision problems. They consist of a frame that holds 2 pieces of glass or plastic that have been ground into lenses to correct refractive errors. Refractive errors may include difficulty seeing far (nearsighted or nearsighted) and near (farsighted or farsighted). They may also include blurring due to an irregular shape of the cornea (astigmatism). Glasses work by increasing or decreasing the focusing power of the eye’s cornea and lens.
How to read an eyeglass prescription
The power of glasses is measured in diopters. This measurement reflects the amount of power required to focus the image directly onto the retina. When looking at an eyeglass prescription, you’ll see the following abbreviations:
OD (Oculus Dexterity): This means right eye (sometimes the abbreviation RE is used).
OS (Oculus Sinister): This means left eye (sometimes the abbreviation LE is used).
An eyeglass prescription may also have the following measurements:
Sphere: This numerical measure reflects the degree of nearsightedness or farsightedness.
Cylinder: This digital measurement shows the amount of astigmatism (the irregularly shaped cornea that causes blur).
Axis: This digital measurement describes the direction of astigmatism in degrees.
Bifocals are extra power in a lens. It lists an additional measurement in the prescription as an “additional” to show the strength of the lens.

Eyeglasses For Children
If your child is old enough, give them an active role in choosing their own glasses. When shopping for glasses for children, consider the following features:
- Shatter resistant and impact resistant lenses, especially for active kids
- Scratch resistant coating on lenses
- Spring loaded frame less likely to bend or warp
- Silicone nose pads to prevent glasses from slipping
- Ear cups (cable temples) around the ears are recommended for children under 4 years old. Shoulder straps can also.

What Is Microfiber Cloth?
Microfibers are polyester and nylon fibers used to make fabrics. When multiple microfibers are woven into a fabric, they create a mesh-like surface that absorbs and traps moisture, dirt and other particles.
The nylon or polyamide in the microfibers has an electrostatic charge that attracts and traps dirt particles, ensuring that dirt adheres to the fabric during cleaning. During the manufacturing process, microfiber towel manufacturers use a chemical process to split the microfibers and create a positive charge. This causes negatively charged dirt and debris to be attracted and stick to the fabric.
Microfibers are about one-sixteenth the thickness of a human hair. As a result, microfiber towels contain more fibers than typical cleaning cloths, making them easier to deep clean surfaces. Many of their fibers can get into pores and crevices that traditional cleaning tools cannot, and absorb tiny particles of dirt and bacteria.
The nylon in the microfiber also helps the microfiber towel absorb and dry quickly. In fact, microfibers can absorb up to seven to eight times their weight in liquids. Microfiber towels can be used wet or dry to clean surfaces and don’t require any additional chemicals or polishes – they remove up to 99% of dust, dirt and other residues on their own. They are considered four times as powerful as conventional cleaners.

How to Clean Eyeglass Frames
Frames have many small parts, such as screws, springs, and hinges, that get dirty with sweat and oil from your face. Dr. Wolf points out that while cleaning the frames is important, people sometimes skip this step.
“Cleaning your frames is important for personal hygiene because frames are constantly in contact with your skin,” he says.
“Most people, even those who normally take good care of their glasses, tend to neglect cleaning their nose pads. This can lead to all sorts of minor skin problems.”
Instructions:
- Run the frame in warm water. Use a mild soap, such as lotion-free dish soap, and apply it to the frame with your fingertips.
- Rinse the frame thoroughly in warm water.
- Use a damp cloth dampened with alcohol to clean the nose pads and earpieces of the frames.
Also Using for Eyeglasses
Dishwashing liquid and water:
According to the American Optometric Association, dishwashing liquid is a great way to clean your glasses. Rub a small amount of dish soap on the lens with your finger. But be sure to avoid citrus-based dish soaps that contain damaging fruit acids or soaps that contain residue.
Lens Cleaning Wipes:
Convenient and easy-to-use prepackaged cleaning wipes are a simple and effective way to clean your lenses.
Spectacle Lens Cleaner and Microfiber Cleaning Cloths:
Spectacle lens cleaners (such as those sold at optical stores) are specially formulated to safely clean glasses, rinse debris and keep lenses smudge-free. Finally wipe with a microfiber cleaning cloth to avoid scratches.
Protect your child’s eyes from sunlight
Parents know they need to protect their children’s skin from harmful sun exposure. But many people forget that eyes also need protection. Nearly 5 in 10 American parents don’t regularly provide their children with sunglasses to protect their eyes from the sun’s ultraviolet (UV) rays. Sun exposure can cause children to develop vision problems later in life.
The sun can cause problems such as sunburned corneas, eyelid cancer, cataracts, and macular degeneration. Also, children are more susceptible because their lenses don’t block UV rays like adult lenses. Children tend to spend more time outdoors than their parents, usually in places with more sunlight reflections. These include beaches, swimming pools and amusement parks. It is also important that your child wears sunglasses in the snow. Most UV damage to the eyes is the result of years of exposure.
Protecting your child’s eyes from the sun is simple:
Have your child wear a wide-brimmed hat that covers his face.
Buy sunglasses for your child that block both types of UV rays. Make sure the sunglasses fit and are comfortable.
