Eyeglasses for 4 Different Purposes
When it comes to eyewear, it’s not necessarily a case of ‘one size fits all’. It is important to have the right tools for the job and use glasses that are appropriate for specific tasks. Here is some information about available eyewear for different purposes.
Eyewear with tinted lenses, created specifically to wear during sports activities enhances performance by improving visual clarity while protecting your eyes from damage.
Sport glasses do not share the same characteristics as regular eyeglasses, sunglasses or industrial safety glasses. Crafted in a variety of shapes, sports eye gear is specialized to suit the specific needs of each respective sport. Many types of eyewear are even designed to fit into helmets worn when playing football, baseball or hockey. Non prescription glasses are available for contact lense wearers to protect their eyes from dust and wind.
If you spend any amount of time working on a computer doing things on your electronic devices like a tablet or phone, you may find that your eyes get tired or blurry after a while. This is because the light that comes from these screens makes your eyes work harder to see contrast. This light is often called “blue light” and it can be very hard on your eyes.
Computer glasses have a special anti-reflective coating or tint that blocks the blue light, lessening the strain on your eyes. They can be prescription or non-prescription. Many types have a special tinting that cuts the glare while increasing the contrast. These precision tinted lenses can help prevent headaches and migraine associated with computer use.
Colour Blindness Glasses
At least eight in 100 men (8%) and one in 200 women (0.5%) suffer from red-green color vision deficiency (CVD), totaling 13 million in the US and 350 million worldwide.
People with normal colour vision can see in excess of one million shades and hues, While those with colour vision deficiency see a vastly diminished range of colors. People with CVD experience colors as more muted and washed out, and some colors cause confusion or are more difficult to differentiate.
Special eyewear is available to help people with colorblindness. This eyewear has specially coloured lenses which enable the wearer to tell the difference between colours more easily. The wearer will see different colours but never see new colours and they will never see colours the same is a person with normal vision.
Presbyopia is an age-related eye condition that causes the eye’s lens to become more rigid over the years, decreasing a person’s near vision. Reading glasses lenses are curved out in shape – convex and make objects that are near look clearer.
Reading glasses come in two main styles: full frames, in which the entire lens is made in the reading prescription, and half eyes which are half-moon shaped and sit lower down on your nose. Half frames are ideal if you are looking down to read but also need to see into the distance when you look up. If you look into the distance with full frames, it will seem blurry.
