How Your Eyes Work

When the light is reflected from the object and enters the eye through the cornea (the transparent outer shell of the eye), the object can be seen.

The cornea bends or refracts the light passing through the pupil of the pupil. The iris (colored part of the eye surrounding the pupil) opens and closes, the pupil becomes larger and smaller. This allows you to adjust the amount of light passing through

The light then passes through the lens and the lens changes shape to further bend the light and focus the light onto the retina. The retina is behind the eye and is a thin tissue layer containing millions of small light-sensitive neurons. These nerve cells are called rods and cones because of their unique shape.

The cone is concentrated in the center of the retina called the macula. When there is bright light, the cone provides clear, sharp central vision and detects color and detail

The rod lies outside the macula and extends all the way to the outer edge of the retina. They provide a peripheral or side view. The stick also allows the eye to detect movement and help us look at dim lights and nighttime

These cells of the retina convert the light into electrical pulses. The optic nerve sends these pulses to the brain to generate images.

By doing this frequently (once a year) it is possible for ophthalmologists to pay close attention to any change (if you allow a bitter tear) before eyesight changes. Your ophthalmologist will ask about your lifestyle and preferences. For example, for athletes who have active lifestyles, it may be better for contact lenses; for frequent flyers that may occasionally need to go to bed, others may be better . Your ophthalmologist also asks if you prefer a color contact lens or one-time contact.

There are three types of contact lenses suitable for people with astigmatism. Soft toric contact lenses, hybrid contact lenses and breathable (hard) contact lenses. To find out which is best for you, please consult an ophthalmologist specializing in contact lens accessories. Consideration varies for each lens type. Your ophthalmologist needs to tell you what is useful for your lifestyle Your ophthalmologist needs to check your eye to decide which type of lens best corrects your sight There is. Of course, comfort is as important as vision correction. Your doctor may try to use multiple lenses to determine the best lens for your eyes.
