7. Eye Melanoma or Ocular Melanoma. Ocular melanoma can be difficult to detect because it develops primarily in the unseen part of the eye and usually does not cause early signs and symptoms. Fortunately, treatment for minor eye melanomas commonly does not interfere with vision. However, treatment for severe eye melanomas can cause some loss of vision.⁣

6. What Are the Qualifications for LASIK Eye Surgery? Since the technology was limited before, LASIK surgery has strict qualifications because they want to limit the risks involved with the treatment as much as possible. Now that the technology has been more advanced and improved, the procedure can accommodate more patients who want LASIK surgery. During 1998, if you have astigmatism you are not qualified to undergo LASIK. Now, you can undergo LASIK surgery even with high amounts of astigmatism. We can observe that with the 21 years there has been so much improvement in technology.

3. Role of CRISPR in Eye Care: DNA Editing. With the advanced technology that we have, a new kind of genetic engineering known as CRISPR allows scientists to edit DNA. CRISPR means “Clustered Regularly Interspaced Short Palindromic Repeats.” The scientists are hoping to repair genetic defects using CRISPR. People are familiar with traditional gene therapy. It works by using viruses to insert new genes into cells that attempt to treat diseases. The CRISPR makes changes directly in the DNA by using targeted molecular tools. To be exact, a scissors that will cut out the abnormal DNA and replace it with normal genetic material.

2. Are There Glasses Available to Correct Colorblindness? There has been an advertisement about new glasses that can improve the color vision of people who have common forms of red-green colorblindness.
