What is LASIK?

Laser In-situ Keratomileusis, better known as LASIK, is a widely popular surgery used to correct vision in people who suffer from nearsightedness, farsightedness, and/or have astigmatism. Such vision conditions are caused by the inability of the cornea, located in the front of the eye, to properly focus light onto the retina, which is located in the back of the eye. LASIK surgery is used to reshape the cornea to bring the light into focus. It is a common alternative for wearers of eyeglasses and/or contact lenses.There are many benefits of LASIK, such as:Over 90% of patients that undergo LASIK surgery will receive their desired result with one surgery.The correction in a patient’s vision is practically immediate, with improved vision within a day after surgeryThere is very little to no discomfort associated with LASIK surgery.LASIK surgery requires no stitches or bandages.After undergoing LASIK surgery, nearly all patients have a reduced dependence on eyeglasses or contact lenses. Many patients have their need for eyeglasses or contact lenses resolved completely......

Is watching movies on a phone damaging to the eyes?

Another classic from a customer earlier today. This time, a teen wondered if she was damaging her eyes by watching movies on her phone.Damaging the eyes, no. Creating the potential for eyestrain, fatigue, and discomfort, yes.Objects that we look at short of about 20 feet require extra focusing and eye alignment efforts. The closer the object, the greater the effort required. Trying to sustain this effort for extended periods is similar to trying to hold a dumbbell in mid air. At some point, the muscles fatigue and, in the case of the eye, results in blur.Television, on the other hand, is usually larger in size and located farther away resulting is less exertion by those same muscles.One more point about these focusing efforts…our abilities decrease as we age. A child could likely sit and watch movies on a phone for hours without too much trouble. Fast forward 20-30 years and that person’s decreased focusing ability would make a phone-based movie marathon near impossible. .....
What is Color Vision Deficiency?

That condition is called achromatopsia and its sufferers can only see the world in black, white and shades of gray.Color blindness or Color Vision Deficiency, is typically inherited, but can also be a result of injury or disease. Injury that damages the optic nerve or retina may be one cause color blindness but there are many more.
