Keeping An Eye On Poor Vision


We all know why we need to wear sunglasses and sunscreen in the summer. Winter, however, can be deceiving. It's an illusion to assume that we are safe from sunburns during the colder season.

Snow acts as a powerful mirror for sunlight and magnifies the effects of UV rays which would otherwise be absorbed by the ground. As a result, the eyes are exposed to both the UV radiation bouncing back from the snowy carpet and the rays shining down directly from the sun.

If your family is skiing or snowboarding up in the mountains, you need to be even more careful! UV rays are more powerful at higher altitudes. Another important factor to remember is that ultraviolet radiation penetrates through clouds, so even if the sun is hidden behind them, it can still damage your eyes.

Prevent overexposure to sunlight by wearing sunglasses that absorb at least 95% of ultraviolet radiation when you go outside, no matter what time of year it is. Even though you want to look great in your shades, the most important part of choosing sunglasses is making sure they provide adequate protection against UV. Make sure the lenses are 100% UV blocking by looking for an indication that they block all light up to 400 nanometers - UV400. The good news is you don't necessarily have to pay more for full coverage for your eyes. Dozens of reasonably priced options exist that still provide total ultraviolet protection.

Another important factor in selecting sun wear is the size of the lenses. You want to make sure your glasses cover as much of the area around your eyes as possible. The more coverage you have, the less harmful radiation will be able to penetrate. Lenses that wrap around the temples will also prevent UV waves from entering from the sides.

If you like to ski or frolic in the snowy hills, you should be aware that the sun's rays are stronger at higher elevations, so you need to be especially careful to keep your eyes shaded on the slopes. In addition to sunglasses, it's a good idea to put on a wide brimmed hat that covers your eyes.

Make a point to be knowledgeable about proper eye protection throughout the year. Don't forget to wear your sunglasses.

Poor vision in adults or children can be due to a few conditions including changes in the body or in the eye, diseases affecting the eye, side effects of medication or injuries to the eye. Many people also experience visual disturbances due to aging or eye strain. These experiences can result in changes in your eyesight, which may sometimes cause discomfort and even make it harder to get through normal activities such as reading books or looking at a computer screen for extended periods of time. These vision problems can be expressed via the following symptoms: eye strain, headache, blurred vision, and struggling with close and far distances.

One of the most common signs of a vision problem can be blurred vision. If you suffer from blurred vision when you're looking at distant objects, you may be nearsighted, or myopic. Blurred vision that's present when you are looking at objects at close range may be a sign of hyperopia, or farsightedness. Blurred vision can also mean you have astigmatism because of an irregularity in the shape of the cornea. Whatever the cause of blurry vision, it is vital that an eye doctor thoroughly check your eyes and prescribe a solution to help clarify your sight.

Sudden flashes of light, sometimes coupled with floating black spots and the sensation of a dark curtain inhabiting a part of your vision indicates the chance of what's known as a retinal detachment. In this case, see your eye doctor as soon as you can, as this can have long-term consequences.

Another warning sign of a vision problem is the inability to distinguish between different colors or brightness of color. This generally means the patient has color blindness. Color blindness is generally not known to the patient until proven with a test. Color blindness is mainly something that affects males. If present in a female it might indicate ocular disease, in which case, an eye doctor needs to be consulted. For people who have difficulty distinguishing objects in dim light, it could mean the patient suffers from night blindness.

Cataracts, a condition frequently seen elderly people can have a number of telltale signs including: hazy sight that worsens in bright light, trouble seeing in the dark or reduced light, trouble seeing small writing or objects, the need for brighter light when reading, unexpected improvement in near vision but a decline in distance vision, painful inflammation of the eye, and a pale appearance to the normally dark pupil.

Throbbing pain in the eye, headaches, unclear sight, inflammation in the eye, rainbow halos around lights, nausea and vomiting are indicators of glaucoma, a serious medical illness, which calls for prompt medical attention.

When it comes to children, it is important to keep an eye out for weak eye movement, or crossed eyes, which may indicate a vision problem called strabismus. Certain behavior in children, like rubbing eyes, squinting, or the need to close one eye to focus better, often point to this issue.

If you experience any of the symptoms we've mentioned here, make an appointment with your eye doctor promptly. Even though some conditions could be more serious than others, any disruption to good vision will be a burden, and impact your quality of life. A brief consultation with your optometrist can prevent being avoidably uncomfortable, or even more severe eye and vision problems.
