Many people who have been able to see their whole life wonder why they start having difficulty seeing near, and feel the need for reading glasses. By the age of 20, slow physiological changes start to happen and the lens, which helps to clearly see objects at different distances, starts to lose elasticity. The lens is inside the eye and changes shape using small muscles, changes the refraction of light at the bottom of the eye, from which it enters the brain as a sharp image. Initially, the effect of the process is invisible, but by the time most people turn 40, they realize their hands are getting "too short".

Presbyopia, or vision changes due to age, is manifested in the weakening of near vision after 40 years of life. At first, it may manifest as eye fatigue at night, at dusk or slow visual acuity at different distances (eg looking into the distance, and then at near). This can also can be a symptom resulting from eyestrain.

Changes always occur, regardless of whether glasses are worn before or not. It is also impossible to slow down age-related weakening of the eye with exercises for the eyes, or in any other way. More noticeable changes of the eye lens come for people around 50 years old, when the prescription for glasses changes faster. Typically, the process slows down around 60 year olds. What to do? It is advisable to check your eyes every year. Presbyopia is corrected with glasses and contact lenses. There are many different types of glasses such as reading glasses, bifocal glasses, office glasses, and progressives. Also, there are different solutions for contact lenses: progressive lenses or conventional contact lenses (one eye is corrected for distance viewing, and the other eye on looking at near). To find the right solution, consult with an optometrist.

For people who have not come into contact with glasses, wearing glasses at first may seem awkward and unfamiliar. But clear vision of life will substantially improve the quality of life, and soon you'll notice that the glasses are not only important to use, and more of an indispensable accessory. For the best choice for eyeglass frames, you will be given advice from optometrists and staff.

Sunglasses are associated with the summer season, when the sun reaches its peak activity. Indeed, in the summer they are badly needed. Through their barrier eyes are protected from UV radiation. It's not just solar radiation. In bright light, the eyes get tired more quickly.

In summer, the sun shines so intense that a person can lose sight a landmark, and not see certain objects. The same can happen in the winter.

It is cold in the winter, but that does not mean that the sun has stopped shining. Some days there is increased activity- bright light literally strikes the eye. The sun's rays reflect from the white surface, giving it more light. To keep your vision, you need to wear sunglasses. This thesis is confirmed by many ophthalmologists. They recommend wearing sunglasses and summer and winter.

Another negative factor in the winter is low humidity. Under the influence of negative temperatures the moisture contained in the air turns into frost and snow. Adding the strong wind, there are conditions for searing eyes - they begin to tear. Frost freezes the tears and the wind drying. Under such adverse moments eyes are unlikely to be healthy. Use sunglasses that will not allow the wind to the eyes.

Do not forget about such vagaries of winter, as blizzards, during which snow whips across the face. As a result, snow fall eye grains, particles of dust, allergens, various chemicals. Sunglasses protect against mechanical impacts, putting a barrier in the way.

Winter sunglasses differ in the fact that they are slightly darkened, and have a curved shape. Weak blackout gives good visibility, and the curved shape protects the eyes from the side. It turns out that the sunglasses forms a protective area that does misses the snow and the wind and allows tears to evaporate.
Glass Winter sunglasses preferred yellow and amber color. At least so say ophthalmologists.

Women who move abroad, are required to wear sunglasses in the winter. They reduce tearing, so in frosty weather eyes should be protected.
