Eye Doctor, Optometrists, Ophthalmologists, Opticians, Eye Exam, San Jose of California

In the United States, optometrists can be found in the vicinity of a chain optical retail store, or in an independent optometrist's office. Optometrists are trained to address both vision refractive errors and eye health. Many optometrists sell high-end eyeglasses and contact lenses in their practices with the most professional possible services in addition to performing eye exams and writing prescriptions. Ophthalmologists are medical doctors (MD) in the eye care and vision health who perform eye exams, write prescription for eyeglasses, sunglasses and contact lenses, diagnose and treat eye diseases and carry out eye surgery. Ophthalmologist's responsibility is much beyond that of optometrist.

  • Oakley is the best in sports sunglasses, I think. You can go to their official site to have a look.

  • There are a several grades of "thin" lens that look like normal lenses. You can choose the high index lenses that can make your lens much thinner ,but usually they are more expensive, but worth it. Any optical shop will have them. Just ask!

  • If your prescription is within the expiration time, you can use your old prescription, but make sure ADD number is on your prescription which is specially needed for reading glasses.If not, you should go and to have your eyes examined again to get a new prescription and tell your doctor this pair is for reading glasses.

  • The power of contacts can be calculated from that of glasses.Here is a formula :Fo=Fs/(1-dFs).The Fo means your power of your contacts and Fs means the power of glasses.dFs means the distance between rear vertex of glasses and your cornea.Usually the dFs should be measured by meter and it is 0.012m for easterners.For example,the RX of glasses is -4.00,the dFs is 0.012m,we can know that your RX for contacts should be -3.82,but this result is not a regular RX,so we choose the proximal and a lower number , it should be -3.75 . Hope these can help. But even if you can make out the RX,you still need an eye exam for contacts.

  • Your glasses prescription may not be the same as your contact lens rx. Getting contacts is not just about getting the right prescription, it is important to get an eye exam as well in order to make sure that it fits. If a lens is not fitting properly on the eye it may cause discomfort and damage to the eye. Although it is a pain and cost some money, it is important to make sure you get fitted with in an examination.

  • I don't think the solution can prolong the life of your contacts. They are only used to clean and disinfect the contacts.Whether it can last long depends on the material properties of the lens itself ,the patient's physiology and the users' care to them.

  • Yes,it is normal.Because the strength you need is usually weaker than the glasses.If they are the same prescription,contacts give you higher prescription to see.So you can see better.

  • Of course they can . It is not hard to find that the majority of sunglass models are full frame ones, because sun glasses are basically expected to cover the whole part of the eyes.But semi rimless sunglasses make it a reality to show more facial natural beauty while ensuring enough UV protection.
